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.
