74LCX652: Low Voltage Transceiver/Register with 5V Tolerant Inputs and Outputs

The LCX652 consists 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 the HIGH logic level. Output Enable pins (OEAB, OEBA#) are provided to control the transceiver function.     The LCX652 is designed for low voltage (2.5V or 3.3V) VCC applications with capability of interfacing to a 5V signal environment.     The LCX652 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation.
