TC74VCXH16374FT
Low-Voltage 16-Bit D-Type Flip-Flop with Bushold
The TC74VCXH16374FT 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 an 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 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.
Weight: 0.25 g (typ.)

•
Latch-up performance: −300 mA
•
ESD performance: Machine model ≥ ±200 V
Human body model ≥ ±2000 V
•
Package: TSSOP

Note 1: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or
even destruction.
Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly
even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute
maximum ratings and the operating ranges.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).
Note 2: OFF state
Note 3: High or low state. IOUT absolute maximum rating must be observed.
