General Description
These devices consist of bus transceiver circuits with D-type flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the input bus or from internal registers. Data on the A or B bus will be clocked into the registers as the appropriate clock pin goes to HIGH logic level. Output Enable pins (OEAB, OEBA) are provided to control the transceiver function.

Features
■ Independent registers for A and B buses
■ Multiplexed real-time and stored data
■ Choice of non-inverting and inverting data paths
