description (continued)
These devices can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. These devices provide
true outputs and symmetrical active-low output-enable (OE
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
) inputs.
When V
However, to ensure the high-impedance state above 1.2 V, OE
is between 0 and 1.2 V , the device is in the high-impedance state during power up or power down.
CC
should be tied to VCC through a pullup resistor;
the minimum value of the resistor is determined by the current-sinking capability of the driver.
All outputs are designed to sink up to 12 mA and include equivalent 30-Ω resistors to reduce overshoot and
undershoot.
The SN54ALVTH162244 is characterized for operation over the full military temperature range of –55°C to
125°C. The SN74ALVTH162244 is characterized for operation from –40°C to 85°C.

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.
