Overview
HD74HC651/HD74HC652 Octal Bus Transceivers/Registers (with inverted 3-state outputs) Octal Bus Transceivers/Registers (with 3-state outputs) Description This device consists of bus transceiver circuits, D-type flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the data bus or from the internal storage registers.
Enable GAB and GBA are provided to cotrol the transceiver functions.
Select AB and Select BA control pins are provided to select whether real-time or stored data is transferred.
A low input level selects real-time data, and a high selects stored data.
The following examples demonstrate the four fundamental bus-management functions that can ...
