GeneralGeneralGeneralGeneral The 74VHC157FT is an advanced high speed CMOS QUAD 2-CHANNEL MULTIPLEXER fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. It consists of four 2-input digital multiplexers with common select and strobe inputs. When the ST input is held level, selection of data is inhibited and all the outputs become level. The SELECT decoding determines whether the A or B inputs get routed to their corresponding Y outputs. An Input protection circuit ensures that 0 to 5.5 V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5 V to 3 V systems and on two supply systems such as battery back up. This circuit prevents device destruction due to mismatched supply and input voltages. 3. 3.
