TOSHIBA TC74VCX257FT

TC74VCX257FT/FK
TOSHIBA CMOS Digital Integrated Circuit
Silicon Monolithic
TC74VCX257FT, TC74VCX257FK
Low Voltage Quad 2-Channel Multiplexer with 3.6 V Tolerant Inputs and Outputs
The TC74VCX257 is a high performance CMOS multiplexer
which is guaranteed to operate from 1.2-V to 3.6-V. Designed for
use in 1.5 V, 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 over voltage tolerant inputs and
outputs up to 3.6 V.
It consists of four 2-input digital multiplexers with common
SELECT and OUTPUTENABLE ( OE ).
If OE is set high the outputs are held in a high-impedance
state. The SELECT decoding determines whether the A or B
inputs get routed to their corresponding Y outputs.
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
