description/ordering information
This single-pole, double-throw (SPDT) analog switch is designed for 1.65-V to 5.5-V V
CC
operation.
The SN74LVC1G3157 can handle both analog and digital signals. The device permits signals with amplitudes
of up to V
CC
(peak) to be transmitted in either direction.
Applications include signal gating, chopping, modulation or demodulation (modem), and signal multiplexing for
analog-to-digital and digital-to-analog conversion systems.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES:
1. All voltages are with respect to ground unless otherwise specified.
2. The input and output voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
3. This value is limited to 5.5 V maximum.
4. VI, VO, VA, and VBn are used to denote specific conditions for VI/O.
5. II, IO, IA, and IBn are used to denote specific conditions for II/O.
6. The package thermal impedance is calculated in accordance with JESD 51-7.

Measured by the voltage drop between I/O pins at the indicated current through the switch. On-state resistance is determined by the lower of
the voltages on the two (A or B) ports.
Specified by design
ron = ron(max) - ron(min) measured at identical VCC, temperature, and voltage levels.
# This parameter is characterized, but not tested in production.
|| Flatness is defined as the difference between the maximum and minimum values of on-state resistance over the specified range of conditions.
k
Ioff is the same as IS(off) (off-state switch leakage current).
