GENERAL DESCRIPTION
The TC446X family of four-output CMOS buffer/drivers are an expansion from our earlier single- and dual-output drivers. Each driver has been equipped with a two-input logic gate for added flexibility.
The TC446X drivers can source up to 250 mA into loads referenced to ground. Heavily loaded clock lines, coaxial cables, and piezoelectric transducers can all be easily driven with the 446X series drivers. The only limitation on loading is that total power dissipation in the IC must be kept within the power dissipation limits of the package.
The TC446X series will not latch under any conditions within their power and voltage ratings. They are not subject to damage when up to 5V of noise spiking (either polarity) occurs on the ground line. They can accept up to half an amp of inductive kickback current (either polarity) into their out­puts without damage or logic upset. In addition, all terminals are protected against ESD to at least 2000V.

ELECTRICAL CHARACTERISTICS: Measured throughout operating temperature range with 4.5V V

≤ 18V,
unless otherwise specified.
NOTES: 1. Totem-pole outputs should not be paralleled because the propagation delay differences from one to the other could cause one driver to
drive high a few nanoseconds before another. The resulting current spike, although short, may decrease the life of the device.
2. When driving all four outputs simultaneously in the same direction, VDD shall be limited to 16V. This reduces the chance that internal dv/dt will cause high-power dissipation in the device.
3. The input threshold has about 50 mV of hysteresis centered at approximately 1.5V. Slow moving inputs will force the device to dissipate high peak currents as the input transitions through this band. Input rise times should be kept below 5 µs to avoid high internal peak currents during input transitions. Static input levels should also be maintained above the maximum or below the minimum input levels specified in the "Electrical Characteristics" to avoid increased power dissipation in the device.

Three components make up total package power
dissipation:
(1) Load-caused dissipation (PL) (2) Quiescent power (PQ) (3) Transition power (PT).
A capacitive-load-caused dissipation (driving MOSFET gates), is a direct function of frequency, capacitive load, and supply voltage. The power dissipation is:
PL = f C V
S
2
,
where: f = Switching frequency
C = Capacitive load VS = Supply voltage.
A resistive-load-caused dissipation for ground-refer­enced loads is a function of duty cycle, load current, and load voltage. The power dissipation is:
PL = D (VS – VL) IL, where: D = Duty cycle
VS = Supply voltage VL = Load voltage IL = Load current.
A resistive-load-caused dissipation for supply-refer­enced loads is a function of duty cycle, load current, and output voltage. The power dissipation is:
PL = D VO IL, where: f = Switching frequency
VO = Device output voltage IL = Load current.
Quiescent power dissipation depends on input signal duty cycle. Logic HIGH outputs result in a lower power dissipation mode, with only 0.6 mA total current drain (all devices driven). Logic LOW outputs raise the current to 4 mA maximum. The quiescent power dissipation is:
PQ = VS (D (IH) + (1–D)IL), where: IH = Quiescent current with all outputs LOW
(4 mA max)
IL = Quiescent current with all outputs HIGH
(0.6 mA max) D = Duty cycle VS =Supply voltage.
Supply Bypassing
Large currents are required to charge and discharge large capacitive loads quickly. For example, charging a 1000 pF load to 18V in 25nsec requires 0.72A from the device's power supply.
To guarantee low supply impedance over a wide fre­quency range, a 1 µF film capacitor in parallel with one or two low-inductance 0.1 µF ceramic disk capacitors with short lead lengths (<0.5 in.) normally provide adequate bypass­ing.
Grounding
The TC4467 and TC4469 contain inverting drivers. Potential drops developed in common ground impedances from input to output will appear as negative feedback and degrade switching speed characteristics. Instead, individual ground returns for input and output circuits, or a ground plane, should be used.
Input Stage
The input voltage level changes the no-load or quies­cent supply current. The N-channel MOSFET input stage transistor drives a 2.5 mA current source load. With logic "0" outputs, maximum quiescent supply current is 4 mA. Logic "1" output level signals reduce quiescent current to 1.4 mA maximum. Unused driver inputs must be connected to V
DD
or VSS. Minimum power dissipation occurs for logic "1" outputs.
The drivers are designed with 50 mV of hysteresis. This provides clean transitions and minimizes output stage cur­rent spiking when changing states. Input voltage thresholds are approximately 1.5V, making any voltage greater than
1.5V up to V
DD
a logic 1 input . Input current is less than 1 µA
over this range.
Power Dissipation
The supply current versus frequency and supply current versus capacitive load characteristic curves will aid in deter­mining power dissipation calculations. TelCom Semicon­ductor's CMOS drivers have greatly reduced quiescent DC power consumption.
Input signal duty cycle, power supply voltage and load type, influence package power dissipation. Given power dissipation and package thermal resistance, the maximum ambient operating temperature is easily calculated. The 14­pin plastic package junction-to-ambient thermal resistance is 83.3°C/W. At +70°C, the package is rated at 800mW maximum dissipation. Maximum allowable chip tempera­ture is +150°C.

Transition power dissipation arises in the complementary configuration (TC446X) because the output stage N-channel and P-channel MOS transistors are ON simultaneously for a very short period when the output changes. The transition power dissipation is approximately:
PT = f VS (10 3 10–9).
Package power dissipation is the sum of load, quies­cent and transition power dissipations. An example shows the relative magnitude for each term:
C = 1000 pF capacitive load
VS= 15V
D = 50%
f = 200 kHz
PD= Package Power Dissipation = PL + PQ + P
T
= 45 mW + 35 mW + 30 mW = 110 mW.
