Texas Instruments 74ACT11656
The 74ACT11656 contains eight noninverting buffers with 3-state outputs and a 9-bit parity generator/checker. The device is intended for bus-oriented applications. The output-enable (OE1, OE2, and OE3) inputs can be used to disable the device so that the buses are effectively isolated.| Part No. | 74ACT11656 |
