description/ordering information
'AHC245 octal transceivers designed asynchronous two-way communication between data buses. control-function implementation minimizes external timing requirements. These devices allow data transmission from from bus, depending logic level direction-control (DIR) input. output-enable (OE) input used disable device that buses effectively isolated. ensure high-impedance state during power power down, should tied through pullup resistor; minimum value resistor determined current-sinking capability driver.
