Part Number: 74AC245
Function: OCTAL BUS TRANSCEIVER WITH 3-STATE OUTPUTS
Package: DIP 20, PLCC 20 Pin
Manufacturer: Texas Instruments
Image and Pinouts:
The 74AC245 octal bus transceivers are 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 device 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.
To ensure the high-impedance state during power up or power down, OEshould be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
