(TOP VIEW)

The ’HC193 are 4-bit synchronous, reversible,

up/down binary counters. Synchronous operation

is provided by having all flip-flops clocked

simultaneously so that the outputs change

coincidentally with each other when so instructed

by the steering logic. This mode of operation

eliminates the output counting spikes normally

associated with asynchronous (ripple-clock)

counters.

LOAD

The outputs of the four flip-flops are triggered on

a low-to-high-level transition of either count

(clock) input (UP or DOWN). The direction of

counting is determined by which count input is

pulsed while the other count input is high.

NC – No internal connection

All four counters are fully programmable; that is, each output may be preset to either level by placing a low on

the load (LOAD) input and entering the desired data at the data inputs. The output changes to agree with the

data inputs independently of the count pulses. This feature allows the counters to be used as modulo-N dividers

by simply modifying the count length with the preset inputs.

A clear (CLR) input has been provided that forces all outputs to the low level when a high level is applied. The

clear function is independent of the count and LOAD inputs.

These counters were designed to be cascaded without the need for external circuitry. The borrow (BO) output

produces a low-level pulse while the count is zero (all outputs low) and DOWN is low. Similarly, the carry (CO)

output produces a low-level pulse while the count is maximum (9 or 15) and UP is low. The counters can then

be easily cascaded by feeding BO and CO to DOWN and UP, respectively, of the succeeding counter.

The SN54HC193 is characterized for operation over the full military temperature range of –55°C to 125°C. The

SN74HC193 is characterized for operation from –40°C to 85°C.
