MC74LVX157

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 = 0.5 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 PIN NAMES Pins I0n I1n E S Zn Function Source 0 Data Inputs Source 1 Data Inputs Enable Input Select Input Outputs TRUTH TABLE INPUTS OUTPUT E S I0n I1n Zn H X X X L L H X L L L H X H H L L L X L L L H X H H = High Voltage Level; L = Low Voltage Level; X = High or Low Voltage Level ; For ICC Reasons DO NOT FLOAT Inputs http://onsemi.com SOIC−16 D SUFFIX CASE 751B TSSOP−16 DT SUFFIX CASE 948F PIN ASSIGNMENT VCC E I0c I1c Zc I0d I1d Zd 16 15 14 13 12 11 10 9 12345678 S I0a I1a Za I0b I1b Zb GND 16...
