High–Performance Silicon–Gate CMOS
The MC54/74HC393A is identical in pinout to the LS393. The device
inputs are compatible with standard CMOS outputs; with pullup resistors,
they are compatible with LSTTL outputs.
This device consists of two independent 4–bit binary ripple counters with
parallel outputs from each counter stage. A ÷ 256 counter can be obtained
by cascading the two binary counters.
Internal flip–flops are triggered by high–to–low transitions of the clock
input. R eset for the c ounters is a synchronous and active–high. State
changes of the Q outputs do not occur simultaneously because of internal
ripple delays. Therefore, decoded output signals are subject to decoding
spikes and should not be used as clocks or as strobes except when gated
with the Clock of the HC393A.
• Output Drive Capability: 10 LSTTL Loads
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 2 to 6 V
• Low Input Current: 1 µA
• High Noise Immunity Characteristic of CMOS Devices
• In Compliance with the Requirements Defined by JEDEC Standard
No. 7A
• Chip Complexity: 236 FETs or 59 Equivalent Gates

This device contains protection
circuitry to guard against damage
due to high static voltages or electric
fields. However, precautions must
be taken to avoid applications of any
voltage higher than maximum rated
voltages to this high–impedance circuit. For proper operation, Vin and
V
out
should be constrained to the
range GND v (Vin or V
out
) v VCC.
Unused inputs must always be
tied to an appropriate logic voltage
level (e.g., either GND or VCC).
Unused outputs must be left open.

PIN DESCRIPTIONS
INPUTS
Clock (Pins 1, 13)
Clock input. The internal flip–flops are toggled and the
counter state advances on high–to–low transitions of t he
clock input.
CONTROL INPUTS
Reset (Pins 2, 12)
Active–high, asynchronous reset. A separate reset is pro-
vided for each counter. A high at the Reset input prevents
counting and forces all four outputs low.
OUTPUTS
