description
These dual 4-bit D-type edge-triggered flip-flops
feature 3-state outputs designed specifically as
bus drivers. They are particularly suitable for
implementing
buffer
registers,
I/O
ports,
bidirectional bus drivers, and working registers.
The edge-triggered flip-flops enter data on the
low-to-high transition of the clock (CLK) input.
The
SN54ALS874B,
SN74ALS874B,
and
SN74AS874 have
clear
(CLR)
inputs
and
noninverting Q outputs. The SN74ALS876A and
SN74AS876 have preset (PRE) inputs and
inverting Q outputs; taking PRE low causes the
four Q or Q outputs to go low independently of the
clock.
The SN54ALS874B is characterized for operation
over the full military temperature range of 55
°C
to 125
°C. The SN74ALS874B, SN74ALS876A,
SN74AS874,
and
SN74AS876 devices
are
characterized for operation from 0
°C to 70°C.
