MM58342

High Voltage Display Driver

General Description

The MM58342 is a monolithic MOS integrated circuit utilizing

CMOS metal gate low threshold P- and N-channel devices. It

is available both in 28-pin molded dual-in-line packages or

as dice. The MM58342 is particularly suited for driving high

voltage (35V max) vacuum fluorescent (VF) displays (e.g., a

20-digit alphanumeric or dot matrix display).
