DESCRIPTION

The UT54ACS193 and the UT54ACTS193 are synchronous 4-

operation is provided by having all flip-flops clocked

simultaneously so that the outputs change coincident with each

output counting spikes normally associated with asynchronous

counters.

level transition of either count input (Up or Down). The direc-

tion of the counting is determined by which count input is pulsed

FUNCTION TABLE

FUNCTION

The counters are fully programmable. The outputs may be pre-

set to either level by placing a low on the load input and entering

agree with the data inputs independently of the count pulses.

Asynchronous loading allows the counters to be used as modu-

preset inputs.

A clear input has been provided that forces all outputs to the low

pendent of the count and the load inputs.

The counter is designed for efficient cascading without the need
