TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74VCXH162374FT
Low-Voltage 16-Bit D-Type Flip-Flop with Bushold
The TC74VCXH162374FT is a high-performance CMOS 16-bit
D-type flip-flop. 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 flip-flop is controlled by a clock input (CK)
and a output enable input (OE) which are common to each byte.
It can be used as two 8-bit flip-flops or one 16-bit flip-flop. 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 resisisors to hold unused or floating
Weight: 0.25 g (typ.)
data inputs at a valid logic level.
All inputs are equipped with protection circuits against static discharge.
