M54537P

MITSUBISHI BIPOLAR DIGITAL ICs M54537P 7-UNIT 3SOmA TRANSISTOR ARRAY DESCRIPTION The M54537P, 7-channel sink driver, consists of 14 NPN tran- sistors connected to form high current gain driver pairs. PIN CONFIGURATION (TOP VIEW) FEATURES Output breakdown voltage to 20V High output sink current to 250mA PMOS Compatible input Low output saturation voltage Wide operating temperature range (Ta =-20-+75°C) INPUT -+ 04 OUTPUT -+ 05 APPLICATIONS Relay and printer driver LED or incandescent display digit driver Interfacing for standard MOS/BIPOLAR logics IN6 -+ -+07 GND Vee Outline 1SP4 FUNCTION The M54537P uses a predriver stage with 2kO series input resistor. The power supply of the predrivers is connected to pin 9 . All emitters and the substrate are connected together to pin 8 . The outputs are capable of sinking 250mA and will withstand 20V in the OFF state. CIRCUIT SCHEMATIC 380 Vee INPUT Zk ZOk *h.. Zk ,, ,, I I I, I I I OUT...
