It is ideal for low power and high speed 3.3V applications; it can be interfaced to 5V signal environment for both inputs and outputs. This device consists of bus transceiver circuits with 3 state, D-type flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the input bus or from the internal storage registers. Enable (GAB) and (GBA) pins are provided to control 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, and a high selects stored data. Data on the A or B bus, or both, can be stored in the internal D flip-flop by low to high transitions at the appropriate clock pins (CAB or CBA) regardless of the select or enable control pins. When select AB and select BA are in the real-time transfer mode, it is also possible to store data 74LCX652 LOW VOLT.
