The MM5452 is a monolithic integrated circuit utilizing CMOS metal gate, low threshold enhancement mode devices. It can drive up to 32 segments of LCD and can be paralleled to increase this number. The chip is capable of driving a 41⁄2-digit 7-segment display with minimal interface between the display and the data source. The MM5452 stores display data in latches after it is clocked in, and holds the data until new display data is received. Features include serial data input, no load signal required, DATA ENABLE (MM5452), wide power supply operation, TTL compatibility, 32 or 33 outputs, alphanumeric and bar graph capability, cascaded operation capability.
