Overview
The LB1720 is an 8-channel transistor array that has a low
output saturation voltage and can be driven by a CMOS
IC. It is especially suited for use in thermal head, LED drive
applications.
Features
• Common-emitter 8-channel transistor array.
• Low output saturation voltage (0.15V typ IO=100mA).
• On-chip base current limiting resistors.
• Capable of being operated directly by TTL, CMOS IC.
