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).
