Overview
The TS5A3157DCKRG4 is a single-channel SPDT analog switch from Texas Instruments, part of the SN74LVC1G3157 series. It operates on a single supply voltage ranging from 1.65V to 5.5V and handles both analog and digital signals with rail-to-rail capability. The device features a low on-resistance of typically 6 ohms at 4.5V and supports signal frequencies up to 300MHz. Packaged in a compact SC-70 (SOT-323) surface-mount housing with six pins, it ensures high linearity and fast switching speeds. It includes robust latch-up protection exceeding 100mA per JESD 78 Class II standards.
Feature Summary
- Supports bidirectional transmission of analog and digital signals up to VCC peak amplitude
- Provides specified break-before-make switching action for reliable signal routing
- Delivers high linearity and low distortion for precision signal processing applications
Applications
- Portable consumer electronics requiring space-constrained signal switching
- Computer peripherals and data acquisition systems
- Audio signal path management and communication networks
Procurement Notes
Verify the G4 suffix indicates lead-free and RoHS-compliant manufacturing status as per Texas Instruments documentation. Confirm the SC-70 package dimensions match your PCB footprint requirements. Ensure the operating temperature range of -40°C to +85°C aligns with your environmental specifications. Cross-reference the datasheet for specific handling and storage guidelines related to moisture sensitivity levels.
Selection Notes
Select this component when a single SPDT configuration is required within a minimal footprint. It is suitable for designs needing operation down to 1.65V while maintaining low on-resistance. Consider its 300MHz bandwidth for high-frequency signal routing tasks. Verify that the 6-pin SC-70 package accommodates your assembly constraints compared to larger alternatives.
Part Context
This part belongs to the SN74LVC1G3157 family of single-pole double-throw analog switches. It shares functional similarities with other devices in the TS5A3157 and SN74LVC1G3157 series but differs in packaging and specific electrical characteristics. The DCKR variant denotes the tape-and-reel SC-70 package format used for automated surface-mount assembly processes.
Replacement Considerations
Publicly confirmed substitutes include the TS5A3157DCKR and the Nexperia 74LVC1G3157GW. Verify pin compatibility and electrical parameters before substitution. Other potential equivalents may include parts from Diodes Incorporated or STMicroelectronics within the same series.
