Description

The SN74AHC245 octal bus transceivers are designed for asynchronous two-way communication between data buses. The control-function implementation minimizes external timing requirements. These SN74AHC245 devices allow data transmission 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 device so that the buses are effectively isolated.

To ensure the high-impedance state during power up or power down, OE should be tied to V_CCthrough a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. The SN54AHC245 is characterized for operation over the full military temperature range of 55°C to 125°C. The SN74AHC245 is characterized for operation from 40°C to 85°C.
