General Description

/ordering information NC – No internal connection The ’HCT652 devices consist 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.

Output-enable (OEAB and OEBA) inputs are provided to control the transceiver functions.

Select-control (SAB and SBA) inputs are provided to select real-time or stored data transfer.
