MC74LVX257 Datasheet, PDF (1/8 Pages) ON Semiconductor – Quad 2-Channel Multiplexer with 3-State Outputs

MC74LVX257
Quad 2−Channel Multiplexer
with 3−State Outputs
The MC74LVX257 is an advanced high speed CMOS quad
2−channel multiplexer fabricated with silicon gate CMOS technology.
It consists of four 2−input digital multiplexers with common select
(S) and enable (OE) inputs. When (OE) 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 inputs tolerate voltages up to 7.0 V, allowing the interface of
5.0 V systems to 3.0 V systems.
Features
• High Speed: t_PD = 4.5 ns (Typ) at V_CC = 3.3 V
• Low Power Dissipation: I_CC = 4 mA (Max) at T_A = 25°C
• High Noise Immunity: V_NIH = V_NIL = 28% V_CC
• Power Down Protection Provided on Inputs
• Balanced Propagation Delays
• Designed for 2.0 V to 5.5 V Operating Range
• Low Noise: V_OLP = 0.8 V (Max)
• Pin and Function Compatible with Other Standard Logic Families
• Latchup Performance Exceeds 300 mA
• Chip Complexity: FETs = 100; Equivalent Gates = 25
• ESD Performance:
Human Body Model > 2000 V;
Machine Model > 200 V
• Pb−Free Packages are Available*
