Texas Instruments TS5N118PW

Overview

TS5N118PW 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 20 pF max OFF-state I/O capacitance on the B port. It serves in PCI interface and memory interleaving applications requiring low-distortion, near-zero propagation delay signal gating.

For engineers reviewing the TS5N118PW datasheet, TS5N118PW pinout, TS5N118PW application, or TS5N118PW equivalent, key selection criteria include its 4.75–5.25 V VCC operation, Ioff partial-power-down support, OE-controlled high-impedance isolation, and TSSOP-14 (PW) package compatibility with space-constrained PCB layouts.

Technical Context

The TS5N118PW implements an integrated charge-pump circuit to elevate the gate voltage of internal pass FETs, enabling flat, low ron across the full 0–10 V I/O voltage range. Its architecture supports true bidirectional data flow without direction control pins and maintains signal integrity via low Cio(OFF) and minimal propagation delay (0.1 ns typical).

It uses three select inputs (S0–S2) to route one of eight B-port channels to the A port under OE low enable logic. The device meets JESD 78 Class II latch-up immunity (>100 mA) and JESD 22 ESD ratings (2000-V HBM, 1000-V CDM), confirming robustness in mixed-signal system environments.

FAQ

What is the maximum operating voltage on the I/O ports of the TS5N118PW?

The TS5N118PW supports a data I/O voltage range of 0 V to 10 V, verified per absolute maximum ratings and recommended operating conditions. This rail-to-rail capability allows the TS5N118PW to handle both standard 5-V digital signals and higher-voltage analog waveforms without external level shifters, making it suitable for mixed-signal routing in systems like test instrumentation and FPGA I/O expansion where signal amplitude varies across channels.

Does the TS5N118PW support partial power-down operation?

Yes, the TS5N118PW is fully specified for partial-power-down applications using its Ioff circuitry. When VCC = 0 V, the TS5N118PW prevents damaging current backflow through the I/O ports, ensuring safe operation during hot-swap or multi-rail power sequencing. This feature is validated per JESD 78 Class II latch-up testing (>100 mA) and is critical for maintaining system reliability in industrial controllers and telecom line cards where subsystems power up/down independently.

What is the typical ON-state resistance of the TS5N118PW and how does it vary with signal voltage?

The TS5N118PW has a typical ON-state resistance (ron) of 3 Ω at VCC = 5 V and IO = ±50 mA, with flat performance across the full 0–10 V I/O range-variation is less than 1 Ω over that span. This flat ron profile is enabled by an internal charge pump and ensures consistent signal attenuation and timing behavior whether routing TTL logic, PCI data bursts, or analog sensor outputs, directly contributing to the TS5N118PW's suitability in precision timing and broadband signal paths.

How many select inputs does the TS5N118PW have, and what addressing scheme do they implement?

The TS5N118PW has three binary select inputs: S0, S1, and S2. These form a 3-bit address that selects one of eight B-port channels (B1–B8) to connect bidirectionally with the A port when OE is low. The function table confirms direct mapping: S2S1S0 = 000 selects B1, 001 selects B2, up to 111 selecting B8. This deterministic 1-of-8 decoding makes the TS5N118PW ideal for address-driven bus multiplexing in microcontroller peripherals and FPGA-based protocol adapters.

What package type and footprint does the TS5N118PW use, and is it RoHS-compliant?

The TS5N118PW uses the TSSOP-14 (PW) package: 4.4 mm × 5.0 mm body, 0.65 mm lead pitch, JEDEC MO-153 compliant, with NiPdAu (NIPDAU) lead finish. It is RoHS-compliant (per TI packaging documentation), rated MSL Level-2 (260°C peak reflow, 1-year floor life), and supplied in tape-and-reel format (2500 units/reel). This compact, surface-mount footprint supports high-density PCB layouts in space-constrained applications such as portable test gear and modular industrial I/O modules.
