MM54C95/MM74C95

4-Bit Right-Shift Left-Shift Register

General Description

Features

Medium speed operation

10 MHz (typ.)

This 4-bit shift register is a monolithic complementary MOS

(CMOS) integrated circuit composed of four D flip-flops.

This register will perform right-shift or left-shift operations

dependent upon the logical input level to the mode control.

A number of these registers may be connected in series to

form an N-bit right-shift or left-shift register.

10V, C

50 pF

(typ.)

High noise immunity

0.45 V

Low power

100 nW/(typ.)

Tenth power TTL compatible

Drive 2 LTTL loads

3V to 15V

Wide supply voltage range

When a logical ‘‘0’’ level is applied to the mode control in-

put, the output of each flip-flop is coupled to the D input of

the succeeding flip flop. Right-shift operation is performed

by clocking at the clock 1 input, and serial data entered at

the serial input, clock 2 and parallel inputs A through D are

inhibited. With a logical ‘‘1’’ level applied to the mode con-

trol, outputs to succeeding stages are decoupled and paral-

lel loading is possible, or with external interconnection, shift-

left operation can be accomplished by connecting the out-

put of each flip-flop to the parallel input of the previous

flip-flop and serial data is entered at input D.

Synchronous parallel load

Parallel inputs and outputs from each flip-flop

Negative edge triggered clocking

The MM54C95/MM74C95 follows the MM54L95/
