TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74VCXR162652FT
Low-Voltage 16-Bit Bus Transceiver/Register with 3.6-V Tolerant Inputs and Outputs
The TC74VCXR162652FT is a high-performance CMOS 16-bit
bus transceiver/register. 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.
This device is bus transceiver with 3-state outputs, D-type
flip-flops, and control circuitry arranged for multiplexed
transmission of data directly from the internal registers.
The 26-Ω series resistor helps reducing output overshoot and
undershoot without external resistor.
Weight: 0.25 g (typ.)
All inputs are equipped with protection circuits against static
discharge.

Bidirectional interface between 2.5 V and 3.3 V signals.
3.6-V tolerant function and power-down protection provided on all inputs and outputs
Note:
Do not apply a signal to any bus pins when it is in the output mode. Damage may result.
All floating (high impedance) bus pins must have their input level fixed by means of pull-up or pull-down
resistors.

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).
