SN74AHCT245/SN74AHCT245-Q1 Octal Bus Transceivers

Texas Instruments SN74AHCT245/SN74AHCT245-Q1 Octal Bus Transceivers are designed for asynchronous two-way communication between data buses. These parts operate from 4.5V to 5.5V. The control-function implementation minimizes external timing requirements. The Texas Instruments SN74AHCT245/SN74AHCT245-Q1 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 are effectively isolated. For the high-impedance state during power up or power down, OE should be tied to V_CC through a pullup resistor; the driver's current-sinking capability determines the resistor's minimum value. The SN74AHCT245-Q1 devices are AEC-Q100 qualified for automotive applications. The SN74AHCT245-EP devices have gold bond wires, a temperature range of –55 to +105°C, and include an SnPb lead finish.
