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
registers,
I/O
ports,
bidirectional bus drivers, and working registers.
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
temperature range of 55
°C to 125°C. The
SN74ALS873B
and
SN74AS873A
are
characterized for operation from 0
°C to 70°C.
