Product Summary

The SN74LVC245A is an octal BUS transceiver with 3-state outputs. The SN74LVC245A is designed for asynchronous communication between data buses. The device transmits data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable the SN74LVC245A so the bus effectively is isolated.

Parametrics

SN74LVC245A absolute maximum ratings: (1)Supply voltage range, VCC: -0.5 to 6.5 V; (2)Input voltage range, VI: -0.5 to 6.5 V; (3)Voltage range applied to any output in the high-impedance or power-off state, VO: -0.5 to 6.5 V; (4)Voltage range applied to any output in the high or low state, VO: -0.5 to VCC + 0.5 V; (5)Input clamp current, VI < 0, IlK: -50mA; (6)Output clamp current, VO < 0, IOK: -50mA; (7)Continuous output current, IO: ±50mA; (8)Continuous current through: ±100mA; (9)Package thermal impedance, DB package: 70℃/W; (10)Storage temperature range, Tstg: -65 to 150℃.
