Product Details
The 74LCX157FT 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 consists of four 2-input digital multiplexers with common SELECT and ST inputs. When the ST input is held"H" level, selection of data is inhibited and all the outputs become "L" level. 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.
Wide operating temperature range: Topr = -40 to 125
Low-voltage operation: VCC = 1.65 to 3.6 V
High-speed operation: tpd = 6.5 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.) 157 type
