Part Number : SN74ACT245
Function : OCTAL BUS TRANSCEIVER WITH 3-STATE OUTPUTS
Package : DIP, SOIC 20 Pin Type
Maker : Texas Instruments
Pinouts : 
Description :
These 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 upon 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 VCCthrough a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
