TC74VCXH162373FT

Low-Voltage 16-Bit D-Type Latch with Bushold

The TC74VCXH162373FT is a high-performance CMOS 16-bit

D-type latch. 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 16-bit D-type latch is controlled by a latch enable input

(LE) and an output enable input ( OE ) which are common to each

byte. It can be used as two 8-bit latches or one 16-bit latch. When

the OE input is high, the outputs are in a high-impedance state.

The 26-Ω series resistor helps reducing output overshoot and

undershoot without external resistor.

The D data inputs include active bushold circuitry, eliminating

the need for external pull-up resistors to hold unused or floating

data inputs at a valid logic level.

All inputs are equipped with protection circuits against static discharge.
