Description

The TC74VCXH16646FT is a high-performance CMOS 16-bit bus transceiver/register. Designed for use in 1.8-V, 2.5-V or 3.3-V systems, it achieves high-speed operation while maintaining the CMOS low power dissipation.

The TC74VCXH16646FT is bus transceiver with 3-state outputs, D-type flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the internal registers.

The A, B data inputs of TC74VCXH16646FT  include active bushold circuitry, eliminating the need for external pull-up resisisors to hold unused or floating data inputs at a valid logic level.

All inputs ofTC74VCXH16646FT are equipped with protection circuits against static discharge.
