Texas Instruments TS5A3159DBVR

Overview

TS5A3159DBVR from Texas Instruments is a single-pole double-throw (SPDT) analog switch with 1 Ω typical ON-state resistance, break-before-make switching, and 1.65 V to 5.5 V single-supply operation. It features 5-V-tolerant control inputs, low charge injection (13–36 pC), and <0.025% THD at 2.5 V - enabling high-fidelity audio routing in portable devices.

For engineers reviewing the TS5A3159DBVR datasheet, TS5A3159DBVR pinout, TS5A3159DBVR application, or TS5A3159DBVR equivalent, key selection criteria include guaranteed break-before-make timing (≤72 ns), sub-1-Ω r_ON flatness (<0.9 Ω), and robust ESD protection (±2000 V HBM), critical for battery-powered consumer interface design.

Technical Context

The TS5A3159DBVR implements a CMOS transmission-gate architecture with complementary P- and N-channel FETs per switch path, ensuring bidirectional analog signal conduction from 0 V to V+. Its break-before-make control logic prevents momentary shorting between NC and NO paths during state transitions.

It operates across four supply rails (1.8 V, 2.5 V, 3.3 V, 5 V) with validated performance: r_ON remains ≤3.2 Ω at 1.8 V, t_BBM stays ≤72 ns, and OFF isolation exceeds –63 dB at 1 MHz - supporting dynamic voltage scaling in modern low-power systems.

FAQ

What is the maximum supply voltage rating for the TS5A3159DBVR?

The TS5A3159DBVR has an absolute maximum supply voltage (V+) of 6.5 V, but its recommended operating range is 1.65 V to 5.5 V. Operation beyond 5.5 V voids parametric guarantees and risks latch-up per JESD 78 Class II testing. The TS5A3159DBVR maintains full functionality and specified r_ON, t_BBM, and THD performance across this 1.65–5.5 V window.

Does the TS5A3159DBVR support bidirectional analog signal flow?

Yes, the TS5A3159DBVR supports fully bidirectional analog signal conduction on all ports (COM, NC, NO). Its CMOS transmission-gate structure allows signals to pass equally well from COM to NC/NO or from NC/NO to COM, with identical r_ON, capacitance, and distortion characteristics in either direction - confirmed in the functional block diagram and electrical characteristics tables of the TS5A3159DBVR datasheet.

Is the TS5A3159DBVR pin-compatible with other SOT-23-6 analog switches?

No, the TS5A3159DBVR uses a proprietary pinout: Pin 1 = NO, Pin 3 = NC, Pin 4 = COM, Pin 6 = IN. This differs from industry-standard layouts like the TS3A226AE (Pin 1 = IN, Pin 2 = GND, Pin 3 = NO, Pin 4 = COM, Pin 5 = NC, Pin 6 = V+). PCB layout must be verified against the TS5A3159DBVR-specific pin configuration diagram - no drop-in replacement is assured without schematic and layout review.

What is the typical charge injection value of the TS5A3159DBVR at 1.8 V supply?

The TS5A3159DBVR exhibits 13 pC typical charge injection (QC) at V+ = 1.8 V, as measured per Figure 19 of the official datasheet. This low value minimizes voltage glitches on high-impedance nodes (e.g., sample-and-hold capacitors or sensor outputs), directly enabling accurate multi-channel data acquisition without additional settling compensation in the TS5A3159DBVR-based design.

How does the TS5A3159DBVR achieve 5-V-tolerant control input while operating from 1.65 V supply?

The TS5A3159DBVR integrates internal level-shifting circuitry that isolates the IN pin from the core switch array. This allows the digital input to accept 0–5.5 V logic levels independent of V+, enabling direct connection to 5-V microcontrollers or FPGAs even when the TS5A3159DBVR itself runs from 1.8 V - a feature explicitly validated in Section 6.5 (Electrical Characteristics for 5-V Supply) of the TS5A3159DBVR datasheet.
