Texas Instruments SN74LV245A Octal Bus Transceivers
Texas Instruments SN74LV245A Octal Bus Transceivers are designed for asynchronous two-way communication between data buses. These parts operate from 2 to 5.5V VCC operation. The control-function implementation minimizes external timing requirements. The Texas Instruments SN74LVT245A devices allow 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.
Features
- 2V to 5.5V VCC operation
