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.
