M54538P

MITSUBISHI BIPOLAR DIGITAL ICs M54538P 7-UNIT 350mA TRANSISTOR ARRAY AND MOTOR DRIVER DESCRIPTION The M54538P, 7-channel sink driver and a motor driver, is deSigned for use in a thermal printer. FEATURES Output breakdown voltage to 20V High output sink current to 350mA Wide operating temperature range (Ta =-20-+75°C) APPLICATIONS Thermal printer driver LED or incandescent display driver Interfacing for standard MOS/BIPOLAR logic FUNCTION The M54538P is designed fOr use in a thermal printer, consisting 7-channel thermal head driver and a D-C or stepper motor driver. The output of the motor driver has a diode for inductive load transient suppression. The outputs of the sink drivers are capaple of sinking 350mA and will withstand 20V in the OFF state.
