description
These 1 1-bit buffers and line drivers are designed
specifically to improve both the performance and
density of 3-state memory address drivers, clock
drivers, and bus-oriented receivers and
transmitters.
The 3-state control gate is a 2-input AND gate with
active-low inputs so that if either output-enable
(OE1
or OE2) input is high, all 1 1 outputs are in the
high-impedance state.
The outputs, which are designed to source or sink
up to 12 mA, include equivalent 25-Ω series
resistors to reduce overshoot and undershoot.
T o ensure the high-impedance state during power
up or power down, OE
should be tied to V
CC
through a pullup resistor; the minimum value of
the resistor is determined by the current-sinking
capability of the driver.
The SN54ABT5400A is characterized for operation over the full military temperature range of –55°C to 125°C.
The SN74ABT5400A 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 EIA/JEDEC Std JESD51.
