Texas Instruments TS5A3359YZPRB

Overview

TS5A3359YZPRB from Texas Instruments is a bidirectional single-pole triple-throw (SP3T) analog switch optimized for low-voltage signal routing, featuring 1.1 Ω typical ON-state resistance at 5 V, 5 pC charge injection at 1.8 V, and break-before-make switching. It operates from 1.65 V to 5.5 V and delivers <0.01% THD in audio paths, making it suitable for portable audio multiplexing in smartphones and wearables.

For engineers reviewing the TS5A3359YZPRB datasheet, TS5A3359YZPRB pinout, TS5A3359YZPRB application, or TS5A3359YZPRB equivalent, key selection criteria include its DSBGA-8 package footprint, 5.5 V-tolerant control inputs, power-down isolation (VCC = 0), and guaranteed r_ON matching ≤0.15 Ω across channels under 3.3 V operation.

Technical Context

The TS5A3359YZPRB implements CMOS transmission-gate architecture with dual digital control inputs (IN1/IN2) enabling three discrete channel selections between COM and NO0/NO1/NO2. Its break-before-make timing (min 0.5 ns, max 80 ns depending on supply) prevents signal shorting during channel transitions.

It supports rail-to-rail analog signal switching (0 V to V_CC) with low capacitance (78 pF ON-state, 18.5 pF OFF-state) and high off-isolation (–64 dB at 1 MHz), ensuring minimal crosstalk and distortion in multi-source audio/video routing applications.

FAQ

What is the maximum analog signal voltage range supported by the TS5A3359YZPRB?

The TS5A3359YZPRB supports rail-to-rail analog signals from 0 V to V_CC. When V_CC = 3.3 V, the valid analog range is 0 V to 3.3 V; at V_CC = 1.8 V, it is 0 V to 1.8 V. This ensures full dynamic range utilization without clipping in low-voltage portable systems. The TS5A3359YZPRB does not support signals exceeding V_CC or going below ground.

Does the TS5A3359YZPRB require external pull-up or pull-down resistors on its IN1 and IN2 control pins?

No, the TS5A3359YZPRB does not require external pull-up or pull-down resistors on IN1 or IN2. Its CMOS inputs have negligible leakage (≤20 nA), and logic thresholds are internally defined: VIH ≥ 2.4 V (5 V supply), ≥2.0 V (3.3 V), or ≥1.5 V (1.8 V). However, TI recommends tying unused control inputs directly to V_CC or GND to prevent floating states that could cause undefined switching behavior in the TS5A3359YZPRB.

How does the TS5A3359YZPRB behave when V_CC = 0 V?

When V_CC = 0 V, the TS5A3359YZPRB enters power-down isolation mode: all switches disconnect, and leakage currents drop to ≤1 μA (ICOM(PWROFF)/INO(PWROFF)). This preserves signal integrity and minimizes system standby current. The TS5A3359YZPRB remains safe for analog voltages up to 5.5 V on NOx/COM pins even with V_CC = 0, thanks to integrated ESD protection diodes.

Can the TS5A3359YZPRB be used to switch differential USB 1.1 signals?

Yes, the TS5A3359YZPRB can route USB 1.1 D+ and D− signals with matched performance: 73 MHz bandwidth at 3.3 V, 78 pF ON capacitance, and <0.35 Ω r_ON flatness ensure minimal skew and attenuation. Its break-before-make timing prevents bus contention during reconfiguration. For full compliance, maintain equal trace lengths and avoid splitting the pair across separate TS5A3359YZPRB units - use one device per differential pair.

What is the thermal resistance (R_θJA) of the TS5A3359YZPRB in its YZP package?

The TS5A3359YZPRB in the 8-pin DSBGA (YZP) package has a junction-to-ambient thermal resistance (R_θJA) of 105.8 °C/W, measured under standard JEDEC JESD51-7 conditions. This value assumes a 1-in² 2-oz copper pad with no airflow. For sustained 100 mA switching current, temperature rise remains below 11 °C - well within safe operating limits. The TS5A3359YZPRB does not require external heatsinking in typical portable applications.
