MITSUBISHI BIPOLAR DIGITAL ICs M54578P 6-UNIT 700mA TRANSISTOR ARRAY WITH CLAMP DIODE AND STROBE DESCRIPTION The M54578P, 6-channel sink driver, consists of 12 NPN transistors connected to form high current gain driver pairs. FEATURES • 20V breakdown • High output sink current to 700mA • PMOS Compatible • Wide operating temperature range (Ta =-20-+75"C) APPLICATIONS • Relay and printer driver • LED or incandescent display digit driver • Interfacing for standard MOS/BIPOLAR logics FUNCTION The M54578P uses a predriver stage. Each input has a diode and 2 kO resistor in series to allow a negative voltage input. All input can be controlled simultaneously by a strobe input at pin I . The power supply of the predrivers is connected to pin 16.
