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

DBV/DCK: The actual top-side marking has one additional character that designates the assembly/test site.  
YEP/YZP: The actual top-side marking has three preceding characters to denote year, month, and sequence code, and one  
following character to designate the assembly/test site. Pin  
1 identifier indicates solder-bump composition  
(1 = SnPb, = Pb-free).

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.
