TC74VCXH16646FT
Low-Voltage 16-Bit Bus Transceiver/Register with Bushold
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.
This device 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 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 are equipped with protection circuits against static
discharge.
Weight: 0.25 g (typ.)
