TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74LCXR164245FT
16-Bit Dual Supply Bus Transceiver with Series Resistor
The TC74LCXR164245FT is a dual supply, advanced high-speed
CMOS 16-bit dual supply voltage interface bus transceiver
fabricated with silicon gate CMOS technology.
Designed for use as an interface between a 5-V bus and a 3.3-V
or 2.5-V bus in mixed 5-V/3.3-V or 2.5-V supply systems, it achieves
high-speed operation while maintaining the CMOS low power
dissipation.
It is intended for 2 way asynchronous communication between
data busses. The direction of data transmission is determined by the
level of the DIR input. The enable input ( OE ) can be used to disable
the device so that the buses are effectively isolated. The B-port
interfaces with the 5-V bus, the A-port with the 3.3-V or 2.5-V-bus.
Weight: 0.25 g (typ.)
The 26-Ω series resistor helps reducing output overshoot and undershoot without external resistor.
All inputs are equipped with protection circuits against static discharge or transient excess voltage.

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 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).
