Description

The 74LCX646 consists of registered bus transceiver circuits,D-type flip-flops, and control circuitry providing multiplexed transmission of data directly from the input bus or from the internal storage registers. Data of the 74LCX646 on the A or B bus will beloaded into the respective registers on the LOW-to-HIGH transition of the appropriate pin (CPAB or CPBA) (see Functional Description).

The 74LCX646 is designed for low voltage (2.5V or 3.3V) VCC applications with capability of interfacing to a 5V signal environment.

The 74LCX646 is fabricated with an advanced CMOS tech- nology to achieve high speed operation while maintaining CMOS low power dissipation.
