MM54HCT193/MM74HCT193

Synchronous Binary Up/Down Counters

General Description

These high speed synchronous counters utilize advanced

silicon-gate CMOS technology to achieve the high noise im-

munity and low power consumption of CMOS technology,

along with the speeds of low power Schottky TTL. The

MM54HCT193/MM74HCT193 is a binary counter having

two separate clock inputs, an UP COUNT input and a

DOWN COUNT input. All outputs of the flip-flops are simul-

taneously triggered on the low-to-high transition of either

clock while the other input is held high. The direction of

counting is determined by which input is clocked.

Both a BORROW and CARRY output are provided to en-

able cascading of both up and down counting functions. The

BORROW output produces a negative-going pulse when

the counter underflows and the CARRY outputs a pulse

when the counter overflows. The counter can be cascaded

by connecting the CARRY and BORROW outputs of one

device to the COUNT UP and COUNT DOWN inputs, re-

spectively, of the next device.

All inputs are protected from damage due to static dis-

charge by diodes to V

and ground.

This device has TTL compatible inputs. It can drive 15 LS-

TTL loads.

Features

This counter may be preset by entering the desired data on

the DATA A, DATA B, DATA C, and DATA D inputs. When

the LOAD input is taken low, the data is loaded indepen-

dently of either clock input. This feature allows the counter

to be used as a divide-by-n counter by modifying the count

length with the preset inputs.

Low quiescent supply current: 80 mA maximum (74HCT

Series)

Low input current: 1 mA maximum

TTL compatible inputs

In addition, the HCT193 can also be cleared. This is accom-

plished by inputting a high on the CLEAR input. All 4 internal

stages are set to a low level independently of either COUNT

input.
