description
The ’ALVTH16827 devices are 20-bit buffers/line drivers designed for 2.5-V or 3.3-V VCC operation, but with
the capability to provide a TTL interface to a 5-V system environment.
The devices are composed of two 10-bit sections with separate output-enable signals. For either 10-bit buffer
section, the two output-enable (1OE1
Y outputs to be active. If either output-enable input is high, the outputs of that 10-bit buffer section are in the
high-impedance state.

description (continued)
When VCC is between 0 and 1.2 V , the device is in the high-impedance state during power up or power down.
However, to ensure the high-impedance state above 1.2 V, OE
the minimum value of the resistor is determined by the current-sinking capability of the driver.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
The SN54ALVTH16827 is characterized for operation over the full military temperature range of –55°C to
125°C. The SN74ALVTH16827 is characterized for operation from –40°C to 85°C.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
2. The package thermal impedance is calculated in accordance with JESD 51.

NOTES: A. CL includes probe and jig capacitance.
B. Waveform 1 is for an output with internal conditions such that the output is low except when disabled by the output control.
Waveform22 is for an output with internal conditions such that the output is high except when disabled by the output control.
C. All input pulses are supplied by generators having the following characteristics: PRR ≤ 10 MHz, ZO = 50 Ω, tr ≤ 2.5 ns, tf ≤ 2.5 ns.
D. The outputs are measured one at a time with one transition per measurement.
