standards to ensure reliable operation over an extended

temperature range. This includes, but is not limited to, Highly

Accelerated Stress Test (HAST) or biased 85/85, temperature

description/ordering information

The SN74AHC245 octal bus transceiver is designed for asynchronous two-way communication between data

buses. The control-function implementation minimizes external timing requirements.

This device allows 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 effectively are isolated.

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
