TC74VCX16835FT
Low-Voltage 18-Bit Universal Bus Driver with 3.6-V Tolerant Inputs and Outputs
The TC74VCX16835FT is a high-performance CMOS 18-bit
universal bus driver. 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.
It is also designed with overvoltage tolerant inputs and outputs
up to 3.6 V.
Data flow from A to Y is controlled by the output-enable (OE)
input.
The device operates in the transparent mode when the
latch-enable (LE) input is high. When LE is low, the A data is
Weight: 0.25 g (typ.)
latched if the clock (CK) input is held at a high or low logic level.
If LE is low, the A data is stored in the latch/flip-flop on the
low-to-high transition of CK.
When OE is high, the outputs are in the high-impedance state.
All inputs are equipped with protection circuits against static discharge.

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).
