Low-Voltage Octal Bus Transceiver with 3.6 V Tolerant Inputs and Outputs
The TC74VCX245 is a high performance CMOS octal bus
transceiver which is guaranteed to operate from 1.2-V to 3.6-V.
Designed for use in 1.5V, 1.8V, 2.5V or 3.3 V systems, it achieves
high speed operation while maintaining the CMOS low power
dissipation.
It is also designed with over voltage tolerant inputs and outputs up
to 3.6 V.
The direction of data transmission is determined by the level of the
DIR inputs. The OE inputs can be used to disable the device so
that the busses are effectively isolated.
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).
Note 2: Off-state
