DESCRIPTION
The UT54ACS164 and the UT54ACTS164 are 8-bit shift reg-
isters which feature AND-gated serial inputs and an asynchro-
nous clear. The gated serial inputs (A and B) permit complete
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.
