The MC74VHC157 is an advanced high speed CMOS quad 2–channel
multiplexer fabricated with silicon gate CMOS technology. It achieves high
speed operation similar to equivalent Bipolar Schottky TTL while maintaining
CMOS low power dissipation.
It consists of four 2–input digital multiplexers with common select (S) and
enable (E) inputs. When E is held High, selection of data is inhibited and all
the outputs go Low.
The select decoding determines whether the A or B inputs get routed to
the corresponding Y outputs.
The internal circuit is composed of three stages, including a buffer output
which provides high noise immunity and stable output. The inputs tolerate
voltages up to 7V, allowing the interface of 5V systems to 3V systems.
High Speed: tPD = 4.1ns (Typ) at VCC = 5V
Low Power Dissipation: ICC = 4
