Product Summary

The SN74AC245DW octal bus transceiver is designed for asynchronous two-way communication between data buses. The control-function implementation minimizes external timing requirements. When the output-enable (OE) is low, the SN74AC245DW passes noninverted 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. A high on OE disables the device so that the buses are effectively isolated.

Parametrics

SN74AC245DW absolute maximum ratings: (1)Supply voltage range, VCC: –0.5 V to 7 V; (2)Input voltage range, VI: –0.5 V to VCC + 0.5 V; (3)Output voltage range, VO: –0.5 V to VCC + 0.5 V; (4)Input clamp current, IIK (VI < 0 or VI > VCC): ±20 mA; (5)Output clamp current, IOK (VO < 0 or VO > VCC): ±20 mA; (6)Continuous output current, IO (VO = 0 to VCC): ±50 mA; (7)Continuous current through VCC or GND: ±200 mA; (8)Maximum power dissipation at TA = 55°C (in still air)(see Note 2): DB package: 0.6 W, DW package: 1.6 W, N package: 1.3 W, PW package: 0.7 W; (9)Storage temperature range, Tstg: –65°C to 150°C.
