MITSUBISHI BIPOLAR DIGITAL ICs
M54512L
4-UNIT SOmA TRANSISTOR ARRAY
DESCRIPTION
The M54512L, 4-channel sink driver, consists of four NPN transistors, and designed for use in medium-current switching applications.
FEATURES
• Output breakdown voltage to 20V • 50mA output sink current capability • Wide operating temperature range (Ta =-20-+75"C)
APPLICATION
LED or incandescent display driver
FUNCTION
The M54512L is comprised of four NPN transistors with a 10kO series input resistor, connected to form dual 2-parallel output drivers. Ali emitters of transistors are connected together to pin 2. The substrate is connected to pin 5 and pin 5 must be tied to the most negative point in the external circuit. The drivers are capable of sinking 50mA and will withstand 20V in the OFF state.
