Overview
The TS5A3157DCKR is a single-channel SPDT analog switch from Texas Instruments, operating on a single supply voltage ranging from 1.65V to 5.5V. It features a maximum on-resistance of 10 ohms and supports bidirectional signal transmission with amplitudes up to VCC. The device is housed in a compact SC-70 (SOT-323) surface-mount package with six pins, measuring 2mm by 1.25mm by 0.9mm. It operates within a temperature range of -40°C to +85°C and includes latch-up protection exceeding 100mA per JESD 78 Class II standards.
Feature Summary
- Supports rail-to-rail signal handling for both analog and digital applications
- Provides break-before-make switching action to prevent signal distortion during channel transitions
- Ensures high linearity and low charge injection for minimal signal degradation
Applications
- Portable consumer devices requiring low power consumption
- Computer peripherals and data acquisition systems
- Audio signal routing and processing circuits
Procurement Notes
Verify the specific ordering suffix DCKR to confirm the SC-70 package type and tape-and-reel packaging configuration. Ensure compatibility with standard surface-mount assembly processes. Confirm RoHS compliance status and absence of halogenated materials as specified in the manufacturer documentation before finalizing procurement orders.
Selection Notes
Select this component when a single-pole double-throw configuration is required for low-voltage logic interfacing. The 10-ohm on-resistance suits general-purpose signal switching rather than high-frequency RF paths. Consider the SC-70 footprint constraints and verify that the 1.65V minimum supply meets the system's active voltage requirements.
Part Context
This part belongs to the TS5A3157 series of low-voltage analog switches designed for portable electronics. It serves as a compact alternative to larger packages while maintaining robust latch-up protection. The series is engineered for applications demanding small form factors and efficient power management in battery-operated environments.
Replacement Considerations
Cross-reference with SN74LVC1G3157DCKR for functional equivalents within the same package. Verify pinout compatibility and electrical parameter alignment before substitution.
