Product details
Overview
TS5N118PWE4 from Texas Instruments is a 1-of-8 FET multiplexer/demultiplexer bus switch optimized for high-bandwidth digital and analog signal routing, featuring 3 Ω typical ON-state resistance (ron), 25 MHz bandwidth, and rail-to-rail 0–10 V switching on I/O ports. It supports bidirectional data flow with near-zero propagation delay (0.1 ns) and is used in PCI interface and memory interleaving applications.
For engineers reviewing the TS5N118PWE4 datasheet, TS5N118PWE4 pinout, TS5N118PWE4 application, or TS5N118PWE4 equivalent, key selection criteria include its low ron flatness over voltage range, Ioff partial-power-down capability, TSSOP-16 package compatibility, and 4.75–5.25 V supply operation in high-speed bus isolation designs.
Technical Context
The TS5N118PWE4 implements an integrated charge-pump circuit to elevate gate voltage of internal pass FETs, enabling low and flat ON-state resistance across 0–10 V signal swing. Its architecture supports true bidirectional signal gating without direction control pins.
It features dedicated OE input for global enable/disable, three binary select inputs (S0–S2) for 1-of-8 channel routing, and NC (no internal connection) terminals at pins 1 and 16. The device meets JESD 78 Class II latch-up immunity (>100 mA) and JESD 22 ESD ratings (2000-V HBM, 1000-V CDM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ON-state resistance (ron) | 3 Ω typical - enables minimal voltage drop and distortion for 50 mA signals across full 0–10 V range |
| Bandwidth | 25 MHz - supports high-fidelity signal transmission up to video and fast digital bus frequencies |
| VCC operating range | 4.75 V to 5.25 V - matches standard 5 V TTL/PCI power rails with ±5% tolerance |
| I/O capacitance (OFF) | 20 pF max (B port) - reduces capacitive loading and crosstalk in dense PCB layouts |
| Propagation delay (tpd) | 0.1 ns - ensures sub-nanosecond timing alignment critical for synchronous bus architectures |
| OFF isolation | –50 dB at 25 MHz - provides strong channel-to-channel signal rejection in multiplexed systems |
| Supply current (ICC) | 10 µA max - enables ultra-low static power in always-on signal-path monitoring circuits |
Pinout & Package
TSSOP-16 (PW) package: 4.4 mm × 5.0 mm body, 0.65 mm pitch, 1.2 mm max height, JEDEC MO-153 compliant, RoHS-compliant NIPDAU lead finish, MSL Level-2-260°C-1 year.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16 | NC | No internal connection - must be left unconnected per TI specification |
| 2 | OE | Active-low output enable - drives entire switch array into high-Z when high |
| 3 | GND | Signal and power reference ground - requires low-impedance local decoupling |
| 4 | VCC | 5 V supply input - must be bypassed with ≥0.1 µF ceramic capacitor near pin |
| 5–7 | S0, S1, S2 | Binary channel select inputs - determine which Bx port connects to A port (000 = B1, 111 = B8) |
| 8–15 | B1–B8 | Eight bidirectional data I/O terminals - each independently routable to A port when selected |
| 9 | A | Common bidirectional data port - connected to selected Bx terminal when OE = L and corresponding S bits active |
Key Features
| Feature | Design Value |
|---|---|
| Charge-pump enhanced FET switch | Eliminates external gate biasing; sustains low ron across full 0–10 V signal swing |
| Ioff partial-power-down protection | Prevents backflow current during VCC ramp-down; maintains isolation between powered/unpowered domains |
| Low-distortion signal gating | Flat ron and <20 pF OFF capacitance preserve signal integrity in analog video and differential clock paths |
| High-speed enable/disable timing | ten/tdis ≤ 200 ns - allows dynamic channel reconfiguration within tight system timing budgets |
| JESD 78 Class II latch-up immunity | Withstands >100 mA transient fault current - suitable for industrial backplane and hot-swap environments |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 1-of-8 analog/digital bus switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74CBT16210DGGR | 10-bit, non-multiplexed bus switch; no select logic; higher ron (6 Ω); 3.3 V only | Lacks S0–S2 decoding; requires external logic for 1-of-8 routing; unsuitable for 5 V PCI | Choose only if fixed 10-channel isolation needed at 3.3 V with no address decoding overhead |
| TS3L110PWR | 10-channel, 3.3 V only; no charge pump; ron = 8 Ω typical; no Ioff support | Cannot operate at 5 V; lacks partial-power-down protection; lower bandwidth (15 MHz) | Select only for cost-sensitive 3.3 V systems where 5 V compatibility and Ioff are not required |
Compared with TS5N118PWE4, SN74CBT16210DGGR offers more channels but no integrated decoding or 5 V support, while TS3L110PWR sacrifices voltage range, power-down safety, and bandwidth for lower cost in non-PCI applications.

FAQ
What is the maximum signal voltage range supported by the TS5N118PWE4?
The TS5N118PWE4 supports 0 V to 10 V switching on its data I/O ports (A and B1–B8), enabling rail-to-rail analog and digital signal handling. This range is validated across the full operating temperature range (–40°C to +85°C) and is independent of VCC, which operates strictly at 4.75–5.25 V.
Does the TS5N118PWE4 support partial power-down operation?
Yes, the TS5N118PWE4 includes Ioff circuitry that disables current backflow when VCC is powered down, ensuring safe isolation between live and unpowered system domains. This feature is explicitly verified per JESD 78 Class II latch-up testing and is functional across all pins including A, B1–B8, and control inputs.
What is the thermal resistance (θJA) of the TS5N118PWE4 in its TSSOP-16 package?
The TS5N118PWE4 in the PW (TSSOP-16) package has a junction-to-ambient thermal resistance (θJA) of 108 °C/W, measured per JESD 51-7 on a standard 4-layer JEDEC test board. This value assumes proper PCB copper pour and thermal vias under the exposed pad region, though the PW package does not include an exposed thermal pad.
How does the charge-pump circuit in the TS5N118PWE4 improve performance?
The internal charge pump in the TS5N118PWE4 elevates the gate voltage of the pass FETs above VCC, sustaining low and flat ON-state resistance (3 Ω typical) across the full 0–10 V signal range. This eliminates ron variation seen in conventional switches and enables consistent signal integrity without external bias components.
Can the TS5N118PWE4 be used in differential signaling applications such as LVDS?
Yes, the TS5N118PWE4 is qualified for differential signal interface applications including LVDS and RSDS due to its low 20 pF OFF-state I/O capacitance, –50 dB crosstalk at 25 MHz, and symmetric bidirectional conduction. Its flat ron and sub-0.1 ns propagation delay preserve phase matching between differential pairs.
