MC74VHCT157A Quad 2−Channel Multiplexer The MC74VHCT157A 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 VHCT inputs are compatible with TTL levels. This device can be used as a level converter for interfacing 3.3 V to 5.0 V because it has full 5.0 V CMOS level output swings. The VHCT157A input structures provide protection when voltages between 0 V and 5.5 V are applied, regardless of the supply voltage. The output structures also provide protection when VCC = 0 V. These input and output structures help prevent device destruction caused by supply voltage−input/output voltage mismatch, battery backup, hot insertion, etc. The inputs tolerate voltages up to 7.0 V, allowing the interface of 5.0 V systems to 3.0 V systems. http://onsemi.com MARKING DIAGRAMS 16 SOIC−16 D SUFFIX CASE 751B 1 VHCT157AG AWLYWW 1 16 VHCT 157A ALYWG G TSSOP−16 DT SUFFIX CASE 948F 1 1 Features • • • • • • • • • • • • High Speed: tPD = 4.1 ns (Typ) at VCC = 5.0 V Low Power Dissipation: ICC = 4 mA (Max) at TA = 25°C TTL−Compatible Inputs: VIL = 0.8 V; VIH = 2.0 V Power Down Protection Provided on Inputs and Outputs Balanced Propagation Delays Designed for 2.0 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: Human Body Model > 2000 V; Machine Model > 200 V Chip Complexity: 82 FETs or 20 Equivalent Gates Pb−Free Packages are Available* 16 SOEIAJ−16 M SUFFIX CASE 966 1 74VHCT157 ALYWG 1 A = Assembly Location WL, L = Wafer Lot Y = Year WW, W = Work Week G or G = Pb−Free Package (Note: Microdot may be in either location) FUNCTION TABLE Inputs E H L L S X L H Outputs Y0 − Y3 L A0 −A3 B0 −B3 A0 − A3, B0 − B3 = the levels of the respective Data−Word Inputs.

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high−impedance circuit. For proper operation, Vin and Vout should be constrained to the range GND v (Vin or Vout) v VCC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused outputs must be left open. Y0 Y1 Y2 Y3 Figure 3.
