Overview
The SN74LVC1G3157YZPR is a single-pole double-throw (SPDT) analog switch from Texas Instruments, designed for operation with a single power supply ranging from 1.65V to 5.5V. It supports bidirectional signal transmission with amplitudes up to VCC(peak). Key electrical parameters include a maximum on-resistance of 15Ω, a -3dB bandwidth of 340MHz, and typical switching times of 0.5ns at 3V. The device features low charge injection of 7pC and off-state leakage current of 1µA. It operates within a temperature range of -40°C to 125°C and is housed in a DSBGA-6 package.
Feature Summary
- Supports rail-to-rail signal handling for both analog and digital applications
- Specified make-before-break switching action to prevent signal interruption
- High linearity and low distortion characteristics suitable for precision signal routing
Applications
- Portable equipment requiring compact signal routing
- Computer peripherals and data acquisition systems
- Audio signal processing and communication networks
Procurement Notes
Verify the specific suffix YZPR corresponds to the DSBGA-6 package and tape-and-reel orientation. Confirm RoHS compliance status and moisture sensitivity level (MSL) ratings prior to assembly. Ensure the ordering part number matches the exact pinout and marking requirements for your PCB design.
Selection Notes
Select this component when a single SPDT analog switch is required in a minimal footprint. Compare against other LVC series switches if higher channel counts or different package types like SC-70 or SOT-23 are needed. Verify that the 15Ω on-resistance meets the impedance matching requirements of the target application circuit.
Part Context
This part belongs to the SN74LVC1G3157 family of single SPDT analog switches. It shares core electrical specifications with variants such as SN74LVC1G3157DCKR and SN74LVC1G3157DSFR, differing primarily in packaging technology and reel configuration. The family is designed for low-voltage portable electronics.
Replacement Considerations
Direct substitutes include SN74LVC1G3157DCKR (SC-70-6) and SN74LVC1G3157DSFR (6-SON). Verify package compatibility and pin alignment before substitution. Other LVC series analog switches may require schematic adjustments due to differing pinouts or electrical characteristics.
