LB1292

The LB1292 is designed for interfacing low level device with fluorescent display tube. 6 independent Darlington output stages can be used to drive digits or segments. With pull-down equivalent resistor built in, no external resistor to prevent ghost is required. When input voltage is at low level, output becomes active.

The features of LB1292 can be summarized as (1)6 independent darlington drivers; (2)capable of driving digits or segments; (3)on-chip sink current circuit for pull-down; (4)rated at 55V 25mA.

The absolute maximum ratings of LB1292 are (1)maximum supply voltage VCC max: -0.3 to +55V; (2)output supply voltage VOUT: -0.3 to VCC V; (3)input supply voltage VIN: -0.3 to +20.0V; (4)output current IQUT: 30 mA; (5)allowable power dissipation Pd max: 960mW; (11)operating temperature Topr: - 20°C to + 75°C; (12)storage temperature Tstg: -40°C to + 150°C; (13)supply voltage VCC: 4.75 to 55.0V; (14)input 'H'-level voltage VIH IOUT=30mA: 2.6 to 20.0V; (15)input 'L'-level voltage VII, IOUT=30A: -0.3 to + 0.3V.
