Product details

Overview

TS5N214DBQR from Texas Instruments is a 2-bit 1-of-4 FET multiplexer/demultiplexer bus switch optimized for high-bandwidth digital and analog signal routing. It features 3 Ω typical ON-state resistance (ron), rail-to-rail 0–10 V switching on I/O ports, bidirectional near-zero propagation delay (3 ns), and 20 pF max OFF-state capacitance at the B port - enabling low-distortion signal gating in PCI and memory interleaving applications.

For engineers reviewing the TS5N214DBQR datasheet, TS5N214DBQR pinout, TS5N214DBQR application, or TS5N214DBQR equivalent, key selection criteria include its dual-channel 1-of-4 select architecture, independent 1OE/2OE enable control, SSOP-16 package compatibility with JEDEC MO-137, and Ioff partial-power-down protection for hot-swap and power-gated systems.

Technical Context

The TS5N214DBQR integrates two independent 1-of-4 FET switches, each with dedicated output-enable (1OE, 2OE) and select (S0, S1) inputs. Its charge-pump gate drive ensures flat ron across the full 0–10 V I/O voltage range, supporting both digital data buses and analog signal paths without distortion.

Each channel operates bidirectionally with no intrinsic directionality; when enabled (OE = LOW), the A port connects to one of four B ports (B1–B4) per the S0/S1 logic state. With OE HIGH, the A–B path enters high-impedance isolation - enhanced by Ioff circuitry that blocks backflow current during VCC power-down.

Key Specifications

Parameter	Value and Actual Design Meaning
ON-state resistance (ron)	3 Ω typical at VCC = 5 V, IO = ±50 mA - enables minimal voltage drop and signal attenuation in high-speed data paths.
I/O voltage range	0 to 10 V - supports rail-to-rail analog and digital signal switching without level-shifting.
Propagation delay (tpd)	3 ns typical (A↔B) - preserves timing integrity in >100 MHz digital interfaces like PCI.
B-port OFF capacitance (Cio(OFF))	20 pF max - reduces capacitive loading on shared buses and maintains signal edge fidelity.
VCC operating range	4.75 V to 5.25 V - compatible with standard 5-V TTL/CMOS logic supply rails.
Bandwidth	25 MHz (–3 dB) - sufficient for baseband video, audio, and medium-speed serial data routing.
OFF isolation	–50 dB at 25 MHz - prevents crosstalk between inactive channels in multi-path systems.

Pinout & Package

TS5N214DBQR is housed in a 16-pin Shrink Small-Outline Package (SSOP-16, DBQ), JEDEC MO-137 compliant, with 0.635 mm lead pitch and 1.75 mm max height. The package supports automated assembly and provides thermal impedance of 90 °C/W (θJA).

Pin/Terminal	Circuit Role	Design Meaning
1OE, 2OE	Channel enable inputs	Active-low enables; each independently controls one 1-of-4 mux/demux channel.
S0, S1	Binary select inputs	Determine which B port (B1–B4) connects to A port per channel (L/L → B1, L/H → B2, etc.).
1A, 2A	Common input/output ports	Bidirectional terminals; connect to system bus or controller interface.
1B1–1B4, 2B1–2B4	Data branch terminals	Four selectable I/O paths per channel; support multiplexed resource sharing or demux distribution.
VCC, GND	Power and reference	Single 5-V supply; GND serves as signal return and substrate reference for all FET channels.

Key Features

Feature	Design Value
Charge-pump gate drive	Enables flat 3 Ω ron across full 0–10 V I/O swing - eliminates voltage-dependent distortion in analog routing.
Ioff partial-power-down protection	Blocks reverse current flow when VCC = 0 V - allows safe insertion/removal in live-backplane systems.
Low OFF-state capacitance	20 pF max at B port - minimizes bus loading and preserves rise/fall times in high-speed parallel interfaces.
Independent dual-channel control	Separate 1OE/2OE and S0/S1 inputs - permits asynchronous routing of two data streams without inter-channel dependency.
ESD robustness	2000-V HBM, 1000-V CDM - withstands handling and board-level ESD events without latch-up or parametric shift.

Equivalent & Alternatives

The following parts are listed as comparable options for similar FET bus switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74CBT3244DBR	8-bit, non-multiplexing, 3.3-V only (VCC = 2.3–3.6 V); ron = 4 Ω typical; no charge pump.	Lacks 1-of-4 select capability and 0–10 V analog support; suited for 3.3-V digital-only bus isolation.	Select when consolidating multiple point-to-point switches instead of multiplexed routing.
TS3L110PW	2-bit 1-of-4, but uses standard CMOS pass gates (no charge pump); ron = 7 Ω typical at 3.3 V; max VI/O = 3.6 V.	Not suitable for 5-V or analog signals beyond 3.6 V; lower bandwidth (15 MHz) and higher capacitance (35 pF).	Choose only for cost-sensitive 3.3-V digital systems where rail-to-rail analog operation is unnecessary.

Compared with SN74CBT3244DBR and TS3L110PW, the TS5N214DBQR uniquely combines 1-of-4 multiplexing, 5-V operation, 0–10 V analog compatibility, and charge-pump-enhanced ron flatness - making it irreplaceable for mixed-signal, high-fidelity bus routing where voltage range and channel count are critical.

FAQ

What is the maximum signal voltage the TS5N214DBQR can switch?

The TS5N214DBQR supports a data I/O voltage range of 0 V to 10 V, verified per absolute maximum ratings and functional specifications. This rail-to-rail capability allows the TS5N214DBQR to handle both digital logic levels and analog signals such as video or sensor outputs without external level-shifting circuitry.

Does the TS5N214DBQR support hot-swap or partial power-down operation?

Yes, the TS5N214DBQR includes Ioff circuitry that actively prevents damaging current backflow when VCC is powered down while I/O pins remain active. This feature makes the TS5N214DBQR suitable for hot-plug applications such as modular backplanes and field-replaceable units where power sequencing cannot be guaranteed.

How many independent signal paths does the TS5N214DBQR provide?

The TS5N214DBQR integrates two fully independent 1-of-4 multiplexer/demultiplexer channels. Each channel has dedicated enable (1OE/2OE), select (S0/S1), common (1A/2A), and branch (1B1–1B4 / 2B1–2B4) terminals - allowing simultaneous, asynchronous routing of two separate data streams.

What is the typical ON-state resistance of the TS5N214DBQR and how does it vary with signal voltage?

The TS5N214DBQR delivers 3 Ω typical ON-state resistance (ron) at VCC = 5 V and IO = ±50 mA. Crucially, its integrated charge pump maintains flat ron across the full 0–10 V I/O voltage range - unlike standard CMOS switches whose ron rises significantly near supply rails.

Is the TS5N214DBQR pin-compatible with other TI bus switches like the TS5A23157?

No, the TS5N214DBQR is not pin-compatible with the TS5A23157. The TS5N214DBQR uses a 16-pin SSOP (DBQ) package with dual 1-of-4 architecture and separate OE/S inputs, whereas the TS5A23157 is a 10-pin DSBGA device implementing a single SPDT switch. Pin mapping, function allocation, and package footprint differ fundamentally.
