LB1720

The LB1720(a kind of thermal head-use, 8-channel) is an 8-channel transistor array that has a low output saturation voltage and oan be driven by a CMOS IC. It is especially suited for use in thermal head, LED drive applications.

The features of LB1720 can be summarized as (1)common-emitter 8-channel transistor array ; (2)low output saturation voltage (0.15V typ Io=100mA) ; (3)on-chip base current limiting resistors ; (4)capable of being operated direct by TTL, CMOS IC

The absolute maximum ratings of LB1720 are (1)output supply voltage VOUT: -0.5 to 18V; (2)output current IOUT(1 unit): 200 mA ; (3)input voltage VIN: -0.5 to 20V; (4)GND Pin Current IGND:900 mA ; (5)allowable power dissipation PS max: 900 mW ; (6)operating temperature Topr: -20 to +75°C ; (7)storage temperature Tstg: -40 to +125°C.
