2-channel analog multiplexer/demultiplexer
1. General description
The 74LVC1G3157 provides one analog multiplexer/demultiplexer with one digital select
input (S), two independent inputs/outputs (Y0, Y1) and a common input/output (Z).
Schmitt trigger action at the select input makes the circuit tolerant of slower input rise and
fall times across the entire VCC range from 1.65 V to 5.5 V.

8. Limiting values
[1] The minimum input voltage rating may be exceeded if the input current rating is observed.
[2] The minimum and maximum switch voltage ratings may be exceeded if the switch clamping current rating is observed.
[3] For SC-88 and SC-74 packages: above 87.5 C the value of Ptot derates linearly with 4.0 mW/K.
For XSON6 package: above 118 C the value of Ptot derates linearly with 7.8 mW/K.
9. Recommended operating conditions
[1] To avoid sinking GND current from terminal Z when switch current flows in terminal Yn, the voltage drop across the bidirectional switch
must not exceed 0.4 V. If the switch current flows into terminal Z, no GND current will flow from terminal Yn. In this case, there is no limit
for the voltage drop across the switch.
[2] Applies to control signal levels.
