Overview
The SN74LVC1G3157YEPR is a single-channel SPDT analog switch from Texas Instruments' LVC series, utilizing advanced CMOS technology. It operates on a single supply voltage ranging from 1.65V to 5.5V and supports bidirectional signal transmission with rail-to-rail capability. The device features a maximum on-resistance of 15 ohms and a -3dB bandwidth of 340MHz. Key electrical parameters include a maximum leakage current of 1µA, charge injection of 7pC, and crosstalk of -54dB at 10MHz. It is housed in an 8-DSBGA package measuring 1.9x0.9mm and functions within a temperature range of -40°C to 85°C.
Feature Summary
- Supports bidirectional signal routing for both analog and digital applications
- Provides high linearity and low distortion for signal integrity
- Features robust ESD protection exceeding JESD 78 Class II standards
Applications
- Portable consumer electronics requiring compact signal switching
- Computer peripherals and data acquisition systems
- Communication networks and signal processing circuits
Procurement Notes
Verify the specific suffix 'YEPR' against the official datasheet to confirm the 8-DSBGA package and tape-and-reel orientation. Ensure the component meets RoHS3 compliance requirements for your target market. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.
Selection Notes
Select this component when a single-pole double-throw configuration is required in a minimal footprint. The 8-DSBGA package suits high-density PCB layouts where space is constrained. Consider the 15-ohm on-resistance and 340MHz bandwidth for high-speed signal routing applications compatible with 1.65V to 5.5V logic levels.
Part Context
This part belongs to the SN74LVC1G3157 family of single SPDT analog switches. While other variants like DBVR or DCKR offer similar electrical performance, they utilize different packages such as SOT-23-6 or SC-70. The YEPR suffix specifically denotes the 8-DSBGA form factor, distinguishing it from surface-mount options with larger footprints.
Replacement Considerations
Direct substitutes include SN74LVC1G3157DBVR and SN74LVC1G3157DCKR, provided the PCB layout accommodates their respective SOT-23-6 or SC-70 packages. Verify pinout compatibility and thermal characteristics when transitioning between these package types.
