Low-Voltage Quad 2-Channel Multiplexer (3-state) with 5-V Tolerant Inputs and Outputs
The TC74LCX257 is a high-performance CMOS multiplexer.
Designed for use in 3.3-V systems, it achieves high-speed
operation while maintaining the CMOS low-power dissipation.
The device is designed for low-voltage (3.3 V) V_CC applications,
but it could be used to interface to 5-V supply environment for
inputs.
It is composed of four independent 2-channel multiplexers with
common select and OE .
If OE is set low, the outputs are held in a high-impedance
state. When SELECT is set low, “A” data inputs are enabled.
Conversely, when SELECT is high, “B” data inputs are enabled.
All inputs are equipped with protection circuits against static
discharge.
Note: xxxFN (JEDEC SOP) is not available in
Japan.
