MM54C90/MM74C90 4-Bit Decade Counter

MM54C93/MM74C93 4-Bit Binary Counter

General Description

The MM54C90/MM74C90 decade counter and the

MM54C93/MM74C93 binary counter and complementary

MOS (CMOS) integrated circuits constructed with N- and

P-channel enhancement mode transistors. The 4-bit decade

counter can reset to zero or preset to nine by applying ap-

All inputs are protected against static discharge damage.

Features

Wide supply voltage range

Guaranteed noise margin

High noise immunity

Low power

3V to 15V

propriate logic level on the R , R , R and R inputs.

(typ.)

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

TTL compatiblity

The MM54C93/MM74C93 follows the MM54L93/

MM74L93 Pinout

logic level on inputs R and R , and a separate flip-flop on

01 02

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.
