description
These dual 4-bit D-type latches feature 3-state
outputs designed specifically for bus driving.
These devices are particularly suitable for
implementing
buffer
bidirectional bus drivers, and working registers.
registers,
I/O
ports,
The dual 4-bit latches are transparent D-type
latches. While the latch-enable (LE) input is high,
the Q outputs follow the data (D) inputs in true
form, according to the function table. When LE is
low, the outputs are latched. When the clear (CLR)
input goes low, the Q outputs go low
independently of LE. The outputs are in the
high-impedance state when the output-enable
(OE) input is at a high logic level.
The SN54ALS873B and SN54AS873A are
characterized for operation over the full military
