Product details

Overview

TS5N214PWG4 from Texas Instruments is a 2-bit 1-of-4 FET multiplexer/demultiplexer bus switch with bidirectional signal routing, 3 Ω typical ON-state resistance (ron), 25 MHz bandwidth, 0–10 V rail-to-rail analog/digital switching capability, and dual independent output-enable (1OE/2OE) control. It serves as a high-bandwidth interface isolator in PCI and memory interleaving systems.

For engineers reviewing the TS5N214PWG4 datasheet, TS5N214PWG4 pinout, TS5N214PWG4 application, or TS5N214PWG4 equivalent, key selection criteria include its flat ron over voltage range, Ioff partial-power-down protection, low 20 pF B-port OFF capacitance, and TSSOP-16 package compatibility with high-density PCB layouts.

Technical Context

The TS5N214PWG4 integrates two independent 1-of-4 FET switches, each controlled by S0/S1 select lines and dedicated OE inputs (1OE, 2OE), enabling simultaneous or isolated channel routing. Its charge-pump gate driver ensures stable ron across 0–10 V I/O swing without external bias.

Each switch supports true bidirectional operation with near-zero propagation delay (3 ns), minimal signal distortion due to low Cio(OFF) = 20 pF (B port), and robust isolation (–50 dB OFF isolation at 25 MHz). The device complies with JESD 78 Class II latch-up (>100 mA) and JESD 22 ESD standards (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 signal attenuation for ±100 mA data paths
Bandwidth	25 MHz - supports high-speed digital interfaces including PCI and differential signaling
I/O voltage range	0 to 10 V - allows rail-to-rail analog and digital signal switching without level translation
B-port OFF capacitance	20 pF max - reduces capacitive loading on shared buses and preserves signal integrity
Supply voltage (VCC)	4.75 V to 5.25 V - matches standard 5-V TTL/CMOS logic rails with tight regulation tolerance
Propagation delay (tpd)	3 ns - ensures sub-nanosecond timing alignment critical for synchronous bus architectures
OFF isolation	–50 dB at 25 MHz - prevents crosstalk between active and disabled channels in multi-lane systems

Pinout & Package

TSSOP-16 package (JEDEC MO-153 compliant), 4.4 mm × 5.0 mm body, 1.2 mm max height, 0.65 mm lead pitch, exposed pad not present.

Pin/Terminal	Circuit Role	Design Meaning
1OE, 2OE	Output-enable control inputs	Active-low enables respective 1-bit mux/demux sections; tied to VCC via pullup for power-up high-Z safety
S0, S1	Channel select inputs	Binary address selects one of four B-port connections (B1–B4) to A port per section
1A, 2A	Common I/O terminals	Bidirectional data path endpoints; connect to system bus or controller interface
1B1–1B4, 2B1–2B4	Independent channel I/Os	Four dedicated signal paths per section; support independent analog/digital routing
VCC, GND	Power supply pins	Single 5-V supply with Ioff protection - blocks reverse current during partial power-down

Key Features

Feature	Design Value
Charge-pump gate drive	Eliminates external VBIAS requirement while maintaining flat ron across full 0–10 V I/O range
Ioff partial-power-down protection	Prevents damaging back-current flow when VCC = 0 V, enabling hot-swap and mixed-voltage system use
Low Cio(OFF) = 20 pF (B port)	Minimizes bus loading and timing skew in high-frequency parallel interfaces like memory interleaving
Dual independent OE control	Allows selective enable/disable of each 2-bit section without affecting the other - ideal for asymmetric bus partitioning
JESD 78 Class II latch-up immunity	Withstands >100 mA transient fault current, supporting robust operation in industrial and telecom infrastructure

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74CBT3245APW	8-bit, single-section, no select inputs; ron = 4 Ω typical, Cio(OFF) = 6 pF	Fixed 1:1 routing only - lacks multiplexing; better for simple bus isolation than dynamic path selection	Choose when channel count >2 and select logic is unnecessary; lower capacitance but no S0/S1 flexibility
TS3L110PW	2-bit, 1-of-4, no charge pump; ron = 7 Ω typical, VIO = 0–5 V only, Cio(OFF) = 12 pF	Limited to 5-V signaling; no rail-to-rail analog support; higher ron increases voltage drop at 100 mA	Choose for cost-sensitive 5-V-only systems where 10-V swing and ultra-low ron are not required

Compared with SN74CBT3245APW and TS3L110PW, the TS5N214PWG4 uniquely combines 0–10 V analog/digital compatibility, charge-pump-enhanced ron flatness, and dual independent OE control - making it the only option among the three qualified for PCI interface and memory interleaving with dynamic channel selection.

FAQ

What is the maximum signal voltage the TS5N214PWG4 can switch?

The TS5N214PWG4 supports a 0 V to 10 V data I/O voltage range (VI/O), verified per Absolute Maximum Ratings and Electrical Characteristics tables. This rail-to-rail capability enables direct interfacing with analog sensors, DAC outputs, and mixed-signal buses without external level-shifting circuitry. The TS5N214PWG4 maintains specified ron and bandwidth performance across this full range when VCC = 4.75–5.25 V.

Does the TS5N214PWG4 support partial power-down operation?

Yes, the TS5N214PWG4 features Ioff circuitry that actively disables current flow between I/O ports when VCC = 0 V, preventing damaging back-current during hot-insertion or mixed-supply sequencing. This behavior is characterized in the Electrical Characteristics table (IOZ = 10 µA max at VCC = 0 V, VI/O = 0–10 V) and explicitly documented in the Functional Description section of the datasheet.

How many independent switching sections does the TS5N214PWG4 contain?

The TS5N214PWG4 contains two fully independent 2-bit 1-of-4 multiplexer/demultiplexer sections: Section 1 (pins 1A, 1B1–1B4, 1OE, S0, S1) and Section 2 (pins 2A, 2B1–2B4, 2OE, S0, S1). Each section has dedicated OE control and shares only the S0/S1 select lines - enabling synchronized or independent channel selection per section.

What is the thermal resistance (θJA) of the TS5N214PWG4 in its TSSOP-16 package?

The TS5N214PWG4 in the PW (TSSOP-16) package has a junction-to-ambient thermal resistance (θJA) of 108 °C/W, as specified in the Absolute Maximum Ratings table. This value assumes standard JEDEC 2-layer board conditions and is used to calculate maximum allowable power dissipation under continuous operation at TA = 85°C.

Is the TS5N214PWG4 pin-compatible with other members of the TS5N214 family?

Yes, the TS5N214PWG4 shares identical pinout and functionality with all TSSOP-packaged variants (TS5N214PW, TS5N214PWR, TS5N214PW.A), differing only in reel/tube packaging and marking suffixes. All PW variants use the same 16-pin TSSOP layout, electrical specifications, and thermal characteristics - allowing direct substitution in existing PCB designs.
