M54521P
5-UNIT SOOmA DARLINGTON TRANSISTOR ARRAY
DESCRIPTION
The M54521 P, 5-channel sink driver, consists of 10 NPNtrar'lsistors connected to form high current gain driver pairs.
FEATURES
• Output sustaining voltage to 30V • High output sink current to 500mA • Wide operating temperature range (Ta =-20-+75"(;)
APPLICATIONS
• Relay and printer drivers • LED or incandescent display digit driver • Interfacing for standard MOS/BIPOLAR logics
FUNCTION
The M54521 P is comprised of five NPN darlington driver pairs. All emitters and the substrate are connected together to pin 7. The output are capable of sinking 500mA and will withstand 30V in the OFF state.
