General Description

n DATA ENABLE (MM5452)

n Wide power supply operation

n TTL compatibility

The MM5452 is a monolithic integrated circuit utilizing

CMOS metal gate, low threshold enhancement mode de-

vices. It is available in a 40-pin molded package. The chip

can drive up to 32 segments of LCD and can be paralleled to

increase this number. The chip is capable of driving a

n 32 or 33 outputs

n Alphanumeric and bar graph capability

n Cascaded operation capability

4¹⁄

-digit 7-segment display with minimal interface between

the display and the data source.

Applications

The MM5452 stores display data in latches after it is clocked

in, and holds the data until new display data is received.

™

n COPS or microprocessor displays

n Industrial control indicator

n Digital clock, thermometer, counter, voltmeter

n Instrumentation readouts

n Remote displays

Features

n Serial data input

n No load signal required
