Advance Information
Quad 2-Channel Multiplexer
The MC74VHCT157A 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 VHCT inputs are compatible with TTL levels. This device can be
used as a level converter for interfacing 3.3 V to 5.0 V because it has full
5 V CMOS level output swings.
The VHCT157A input structures provide protection when voltages
between 0 V and 5.5 V are applied, regardless of the supply voltage. The
output structures also provide protection when VCC = 0 V. These input and
output structures help prevent device destruction caused by supply
voltage—input/output voltage mismatch, battery backup, hot insertion, etc.
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 = 4A (Max) at TA = 25°C
TTL–Compatible Inputs: VIL = 0.8 V; VIH = 2.0 V
Power Down Protection Provided on Inputs and Outputs
Balanced Propagation Delays
Designed for 2V to 5.5V Operating Range
Low Noise: VOLP = 0.8V (Max)
Pin and Function Compatible with Other Standard Logic Families
Latchup Performance Exceeds 300mA
ESD Performance: HBM > 2000V; Machine Model > 200V
Chip Complexity: 82 FETs or 20 Equivalent Gates
