MC74VHC157
Quad 2- Channel Multiplexer
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 7 V, allowing the interface of 5 V systems
to 3 V systems.
• High Speed: tPD = 4.1 ns (Typ) at VCC = 5 V
• Low Power Dissipation: ICC = 4 mA (Max) at TA = 25°C
• High Noise Immunity: VNIH = VNIL = 28% VCC
• Power Down Protection Provided on Inputs
• Balanced Propagation Delays
• Designed for 2 V to 5.5 V Operating Range
• Low Noise: VOLP = 0.8 V (Max)

• Pin and Function Compatible with Other Standard Logic Families
• Latchup Performance Exceeds 300 mA
• ESD Performance: HBM > 2000 V; Machine Model > 200 V
• Chip Complexity: 82 FETs
• These devices are available in Pb--free package(s). Specifications herein
apply to both standard and Pb--free devices. Please see our website at
www.onsemi.com for specific Pb--free orderable part numbers, or
