General Description
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 com-
mon 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 deter-
mines whether the I
responding 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.
