MM54C195/MM74C195 4-Bit Registers

General Description

Features

Medium speed operation

8.5 MHz (typ.) with 10V

supply and 50 pF load

The MM54C195/MM74C195 CMOS 4-bit registers feature

parallel inputs, parallel outputs, J-K serial inputs, shift/load

control input and a direct overriding clear. The following two

modes of operation are possible:

High noise immunity

0.45 V (typ.)

Low power

100 nW (typ.)

Drive 2 LPTTL loads

3V to 15V

Parallel Load

Tenth power TTL compatible

Supply voltage range

Shift in direction Q towards Q

Synchronous parallel load

Parallel loading is accomplished by applying the four bits of

data and taking the shift/load control of input low. The data

is loaded into the associated flip-flops and appears at the

outputs after the positive transition of the clock input. During

parallel loading, serial data flow is inhibited.

Parallel inputs and outputs from each flip-flop

Direct overriding clear

J and K inputs to first stage

Complementary outputs from last stage

Positive-edge triggered clocking

Serial shifting is accomplished synchronously when the

shift/load control input is high. Serial data for this mode is

entered at the J-K inputs. These inputs allow the first stage

to perform as a J-K, D, or T-type flip flop as shown in the

truth table.

Diode clamped inputs to protect against static charge
