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
Weight: 0.25 g (typ.)
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.
