M54517P
7·UNIT 400rnA DARLINGTON TRANSISTOR ARRAY
DESCRIPTION
The M54517P, 7-channel sink driver, consists of 14 NPN transistors connected to form seven high current gain driver pairs.
FEATURES
• Output sustaining voltage to 25V • High output sink current to 400mA • PMOS Compatible input • 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 M54517P is comprised of seven NPN darlington driver pairs with 20kO series input resistors. All emitters and the substrate are connected to pin 8. The output are capable of sinking 400mA and will withstand 25V in the OFF state.
