MM74C90 • MM74C93 4-Bit Decade Counter • 4-Bit Binary Counter

October 1987

Revised May 2002

MM74C90 • MM74C93

4-Bit Decade Counter • 4-Bit Binary Counter

General Description

The MM74C90 decade counter and the MM74C93 binary

counter and complementary MOS (CMOS) integrated cir-

cuits constructed with N- and P-channel enhancement

mode transistors. The 4-bit decade counter can reset to

zero or preset to nine by applying appropriate logic level on

the R

, R

and R

inputs. Also, a separate flip-flop

on the A-bit enables the user to operate it as a divide-by-2,

5 or 10 frequency counter. The 4-bit binary counter can be

reset to zero by applying high logic level on inputs R

and

, and a separate flip-flop on the A-bit enables the user

to operate it as a divide-by-2, -8, or -16 divider. Counting

occurs on the negative going edge of the input pulse.

All inputs are protected against static discharge damage.

Features

Wide supply voltage range:

3V to 15V

Guaranteed noise margin: 1V

High noise immunity: 0.45 V

(typ.)

Low power compatibility:

Fan out of 2 TTL driving 74L

The MM74C93 follows the MM74L93 Pinout
