DESCRIPTION
The UT54ACS163 and the UT54ACTS163 are synchronous
presettable 4-bit binary counters that feature internal carry look-
ahead logic for high-speed counting designs. Synchronous op-
eration occurs by having all flip-flops clocked simultaneously
so that the outputs change coincident with each other when in-
structed by the count-enable inputs and internal gating. A buff-
ered clock input triggers the four flip-flops on the rising (posi-
tive-going) edge of the clock input waveform.
The counters are fully programmable (i.e., they may be preset
to any number between 0 and 15). Presetting is synchronous;
applying a low level at the load input disables the counter and
causes the outputs to agree with the load data after the next clock
pulse.
The clear function is synchronous and a low level at the clear
input sets all four of the flip-flop outputs low after the next clock
pulse. This synchronous clear allows the count length to be mod-
ified by decoding the Q outputs for the maximum count desired.
The counters feature a fully independent clock circuit. Changes
at control inputs (ENP, ENT, or LOAD) that modify the operat-
ing mode have no effect on the contents of the counter until
clocking occurs. The function of the counter (whether enabled,
disabled, loading, or counting) will be dictated solely by the
conditions meeting the stable setup and hold times.
The devices are characterized over full military temperature
range of -55°C to +125°C.

2. All specifications valid for radiation dose 1E6 rads(Si).
3. Based on characterization, hold time (tH1) of 0ns can be assumed if data setup time (tSU1) is >10ns. This is guaranteed, but not tested.
