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: tPD = 5.1 ns (Typ) at VCC = 3.3 V • Low Power Dissipation: ICC = 4 mA (Max) at TA = 25°C • Power Down Protection Provided on Inputs • Balanced Propagation Delays • Low Noise: VOLP = 0.
