The UT54ACS164E and the UT54ACTS164E are 8-bit shift
registers which feature AND-gated serial inputs and an asyn-
chronous clear. The gated serial inputs (A and B) permit com-
plete control over incoming data. A low at either input inhibits
entry of new data and resets the first flip-flop to the low level
at the next clock pulse. A high-level at both serial inputs sets
the first flip-flop to the high level at the next clock pulse. Data
at the serial inputs may be changed while the clock is high or
low, providing the minimum setup time requirements are met.
Clocking occurs on the low-to-high-level transition of the clock
input.
The devices are characterized over full military temperature
range of -55°C to +125°C.
