Texas Instruments TS5N118PWR

Overview

TS5N118PWR from Texas Instruments is a 1-of-8 FET multiplexer/demultiplexer bus switch optimized for high-bandwidth digital and analog signal routing. It features 3 Ω typical ON-state resistance (ron), 25 MHz bandwidth, bidirectional rail-to-rail switching (0–10 V), and operates from 4.75 V to 5.25 V. It enables low-distortion data path selection in PCI interfaces and memory interleaving systems.

For engineers reviewing the TS5N118PWR datasheet, TS5N118PWR pinout, TS5N118PWR application, or TS5N118PWR equivalent, key selection criteria include its 3 Ω ron flatness over voltage range, 20 pF max OFF-state I/O capacitance, Ioff partial-power-down protection, and TSSOP-16 (PW) package compatibility with high-density PCB layouts.

Technical Context

The TS5N118PWR implements an 8-channel FET-based analog/digital switch architecture with integrated charge pump to maintain low and flat ON-resistance across the full 0–10 V I/O swing. Its internal enable logic responds to OE, S0, S1, and S2 inputs to route A port bidirectionally to one of eight B ports (B1–B8).

It supports partial-power-down operation via Ioff circuitry that blocks reverse current flow when VCC = 0 V, ensuring bus isolation during power sequencing. The device meets JESD 78 Class II latch-up immunity (>100 mA) and JESD 22 ESD ratings (2000-V HBM, 1000-V CDM).

FAQ

What is the maximum signal voltage range supported by the TS5N118PWR?

The TS5N118PWR supports a 0 V to 10 V data I/O voltage range (VI/O) across its A and B ports. This rail-to-rail capability allows the TS5N118PWR to handle both standard 5-V digital logic and analog signals without attenuation or clipping, provided VCC remains within its 4.75 V to 5.25 V operating range.

Does the TS5N118PWR support partial-power-down operation?

Yes, the TS5N118PWR includes Ioff circuitry that actively disables current flow when VCC = 0 V. This feature prevents damaging backflow current through the TS5N118PWR during power sequencing or hot-swap events, ensuring safe isolation between powered and unpowered subsystems in modular designs.

What is the typical ON-state resistance of the TS5N118PWR and how does it vary?

The TS5N118PWR has a typical ON-state resistance (ron) of 3 Ω at VCC = 5 V and ±50 mA load. Per Figure 1 in the datasheet, ron remains flat across the full 0–10 V I/O voltage range due to its internal charge-pump gate drive - a key differentiator of the TS5N118PWR versus conventional analog switches.

Can the TS5N118PWR be used for bidirectional signal routing?

Yes, the TS5N118PWR supports fully bidirectional data flow between its A port and any selected B port (B1–B8). There is no inherent directionality - signals pass equally well from A to Bx or Bx to A, with near-zero propagation delay (<0.1 ns) and symmetric ron in both directions, as confirmed in the TS5N118PWR functional description and logic diagram.

What package type is used for the TS5N118PWR and what are its key mechanical dimensions?

The TS5N118PWR uses a TSSOP-16 (PW) package: 4.4 mm × 5.0 mm body size, 0.65 mm lead pitch, 1.2 mm maximum height, and JEDEC MO-153 compliant. Its compact footprint and gull-wing leads support fine-pitch automated assembly and high-density PCB layouts typical in networking and industrial control modules.
