description
These 12-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 12 outputs are in the
high-impedance state. These devices provide
inverted data.
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 SN54ABT5403 is characterized for operation over the full military temperature range of –55°C to 125°C.
The SN74ABT5403 is characterized for operation from –40°C to 85°C.
