Overview

The VHC157 is an advanced high speed CMOS Quad 2-Channel Multiplexer fabricated with silicon gate CMOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. It consists of four 2-input digital multiplexers with common select and enable inputs. When the ENABLE# input is held "H" level, selection of data is inhibited and all the outputs become "L" level. The SELECT decoding determines whether the I0x or I1x inputs get routed to their corresponding outputs. An Input protection circuit ensures that 0V to 7V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5V to 3V systems and on two supply systems such as battery back up. This circuit prevents device destruction due to mismatched supply and input voltages.

  • This product is general usage and suitable for many different applications.

  • High Speed: tPD = 4.1 ns (typ) at VCC = 5V
  • Low power dissipation: ICC = 4 µA (max.) at TA = 25°C
  • High noise immunity: VNIH = VNIL = 28% VCC (min.)
  • Power down protection is provided on all inputs
  • Low noise: VOLP = 0.8V (max.)
  • Pin and function compatible with 74HC157

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
