Overview
The TS5A3159DCKR is a single-pole double-throw (SPDT) solid-state analog switch manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 5.5 V and features a low on-resistance of 1 Ω with excellent on-resistance matching. The device includes break-before-make switching to prevent signal distortion during channel transitions. Key electrical parameters include an on-capacitance of 84 pF, an on-time of 20 ns, an off-time of 15 ns, and a bandwidth of 100 MHz. Charge injection is specified at 36 pC. It functions in temperatures from -40°C to +85°C and is housed in a 6-pin SC-70 package.
Feature Summary
- Break-before-make switching prevents signal distortion during channel transitions
- Low on-resistance ensures minimal signal loss
- Control inputs withstand 5 V voltage levels for logic compatibility
- Low charge injection maintains signal integrity
Applications
- Portable audio equipment
- Mobile phones
- Consumer electronics and computers
- Portable instruments
Procurement Notes
Verify the specific suffix DCKR against the manufacturer datasheet to confirm the SC-70-6 packaging and tape-and-reel configuration. Ensure the component meets JESD 78 Class II latch-up standards and required ESD protection ratings for the target application environment before finalizing procurement.
Selection Notes
Select this component when low distortion and high signal fidelity are critical for portable audio or data paths. The 1.65 V to 5.5 V operating range allows compatibility with various logic families. Verify that the 1 Ω on-resistance and 84 pF capacitance meet the bandwidth and insertion loss requirements of the specific analog signal path.
Part Context
The TS5A3159DCKR belongs to the TS5A3159 family of analog switches designed for space-constrained portable applications. It serves as a low-cost, low-power alternative to mechanical relays in signal routing scenarios where small form factor and fast switching speeds are required.
Replacement Considerations
Publicly documented equivalent part numbers include TS5A3159ADCKR and TS5A3159ADCKRE4. These variants share the same functional specifications and pinout but may differ in manufacturing lot codes or specific environmental compliance markings.
