MC74LVX157_14 Datasheet, PDF (1/6 Pages) ON Semiconductor – Quad 2-Channel Multiplexer

MC74LVX157
Quad 2-Channel Multiplexer
With 5 V−Tolerant Inputs
The MC74LVX157 is an advanced high speed CMOS quad
2−channel multiplexer. The inputs tolerate voltages up to 7.0 V,
allowing the interface of 5.0 V systems to 3.0 V systems.
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 I0 n or I1 n inputs get
routed to the corresponding Z n outputs.
Features
• High Speed: t_PD = 5.1 ns (Typ) at V_CC = 3.3 V
• Low Power Dissipation: I_CC = 4 mA (Max) at T_A = 25°C
• Power Down Protection Provided on Inputs
• Balanced Propagation Delays
• Low Noise: V_OLP = 0.5 V (Max)
• Pin and Function Compatible with Other Standard Logic Families
• Latchup Performance Exceeds 300 mA
• ESD Performance:
Human Body Model > 2000 V;
Machine Model > 200 V
• These Devices are Pb−Free and are RoHS Compliant
