DESCRIPTION

The M54972 is a semiconductor integrated circuit consisting of 8 stages of CMOS shift registers and latches with serial inputs and serial or parallel outputs. It is based on Bi-CMOS process technology, and has 8 bipolar drivers at the parallel outputs.

FEATURES

● Serial input and serial or parallel output

● Serial output enables cascade connection

● Built-in latch for each stage

● Enable input provides output control

● Low supply current (standby current ICC ≤ 10µA)

● Serial I/O level is compatible with typical CMOS devices

● Driver features: High withstand voltage (BVCEO ≥ 30V) Capable of large drive currents (IO(max)=300mA) Low output saturation voltage VOL < 0.6V at lo=300mA

● Wide operating temperature range Ta=-20 – +75°C

APPLICATION

Dot drivers for thermal print heads. Serial/parallel conversion.

Drivers for relays and solenoids.
