Texas Instruments TS5A12301EYFPR

Overview

TS5A12301EYFPR from Texas Instruments is a bidirectional, single-pole double-throw (SPDT) analog switch in a 6-pin DSBGA package (1.16 mm × 0.76 mm), featuring 0.75 Ω typical ON-state resistance at 5 V, ±8-kV IEC 61000-4-2 contact ESD protection on COM, and 1.8-V compatible logic input independent of VCC supply. It operates from 2.25 V to 5.5 V and is optimized for portable audio signal routing in space-constrained handheld devices.

For engineers reviewing the TS5A12301EYFPR datasheet, TS5A12301EYFPR pinout, TS5A12301EYFPR application, or TS5A12301EYFPR equivalent, key selection criteria include guaranteed break-before-make timing (≤35 ns max), low charge injection (82–97 pC), THD < 0.008% at 2.5 V, and power-down isolation with VCC = 0 V.

Technical Context

The TS5A12301EYFPR implements a CMOS transmission-gate architecture with dual-channel (NC/NO) SPDT switching controlled by a single digital IN input. Its break-before-make timing ensures no signal shorting during path transition, critical for audio and ADC front-end multiplexing.

It features internal 6-MΩ pulldown on the IN pin enabling unconnected control operation, and its COM port meets IEC Level 4 ESD (±8-kV contact, ±15-kV air-gap), making it suitable for direct interface with exposed connectors in consumer electronics.

Key Specifications

FAQ

What is the maximum operating temperature for the TS5A12301EYFPR?

The TS5A12301EYFPR is rated for continuous operation from –40°C to +85°C ambient temperature. Electrical characteristics-including ON-resistance, leakage current, and switching times-are fully specified across this range per JEDEC JESD22-A108. Thermal derating is not required within these limits, and the device's RθJA of 123.4°C/W ensures safe junction temperatures under typical PCB copper pour conditions.

Does the TS5A12301EYFPR require external pull-up or pull-down resistors on the IN pin?

No, the TS5A12301EYFPR includes an internal 6-MΩ pulldown resistor on the IN pin, allowing it to be left unconnected (floating) to default to NC connection. This eliminates external components and reduces BOM cost and board area. When driven actively, the IN pin accepts 1.8-V logic levels regardless of VCC, supporting direct interface with low-voltage microcontrollers without level translation.

Can the TS5A12301EYFPR be used with a 1.8-V supply voltage?

No-the TS5A12301EYFPR requires a minimum VCC of 2.25 V per its Recommended Operating Conditions. While its IN pin is 1.8-V logic compatible, the internal switch transistors need ≥2.25 V to achieve specified ON-resistance (≤1.6 Ω) and leakage performance. Operating below 2.25 V may result in increased ron, higher THD, and unreliable switching behavior outside datasheet guarantees.

How does the TS5A12301EYFPR handle ESD events on the COM pin?

The TS5A12301EYFPR provides IEC 61000-4-2 Level 4 ESD protection on the COM pin: ±8-kV contact discharge and ±15-kV air-gap discharge relative to GND. This is implemented via integrated silicon-controlled rectifier (SCR) clamps and diode structures, verified per JESD22-C101 and JESD22-A114. No external TVS diodes are needed for standard handheld ESD compliance when COM interfaces directly with connectors.

Is the TS5A12301EYFPR pin-compatible with other TI SPDT switches in YFP packaging?

Yes-the TS5A12301EYFPR shares identical YFP (6-pin DSBGA) pinout and footprint with TI's TMUX12301YFPR and TS5A3154YFPR. However, functional differences exist: TMUX12301YFPR lacks IEC Level 4 COM ESD, and TS5A3154YFPR has no internal IN pulldown. Mechanical compatibility enables footprint reuse, but design validation is required for ESD and biasing behavior.
