Product Details

The 74LCX257FT 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) VCC 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 high, 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.

Wide operating temperature range: Topr = -40 to 125 
Low-voltage operation: VCC = 1.65 to 3.6 V
High-speed operation: tpd = 7.0 ns (max) (VCC = 3.3 ± 0.3 V)
Output current: |IOH|/IOL = 24 mA (min) (VCC = 3.0 V)
Power-down protection provided on all inputs and outputs
Pin and function compatible with the 74 series
(74LVC/ALVC/ etc.) 257 type
