SG55451BL

The SG55451BL is designed as one kind of dual peripheral positive-AND drivers for use in systems that employ TTL or DTL logic. Typical applications include high speed logic buffers, power drivers, relay drivers, MOS drivers, line drivers and memory drivers.

SG55451BL has six features. (1)300mA output current capability. (2)High voltage output. (3)No output latch-up at 200V. (4)High speed switching. (5)TTL or DTL compatible diode-clamped inputs. (6)Standard supply voltages. Those are all the main features.

Some absolute maximum ratings of SG55451BL have been concluded into several points as follow. (1)Its supply voltage would be 7V. (2)Its input voltage would be 5.5V. (3)Its interemitter would be 5.5V. (4)Its off-state output voltage would be 30V. (5)Its output current would be 400mA. (6)Its continuous total dissipation 25°C free-air temperature would be 800mW. (7)Its operating junction temperature hermetic would be 150°C. (8)Its storage temperature range would be from -65°C to 150°C. (9)Its lead temperature 1/16 inch from case for soldering 60 seconds would be 300°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of SG55451BL are concluded as follow. (1)Its high level input voltage would be min 2V. (2)Its low level input voltage would be max 0.8V. (3)Its input clamp voltage would be typ -1.2V and max -1.5V. (4)Its high level output current would be max 300uA. (5)Its low level output voltage would be typ 0.25V and max 0.5V at Iol=100mA and would be typ 0.5V and max 0.8V at Iol=300mA. (6)Its input current at max vin would be max 1.0mA. (7)Its high level input current would be max 60uA. (8)Its low level input current would be typ -1.0mA and max -1.6mA. And so on.
