TS5N412PW

Overview

The TS5N412PW is a 4-bit 1-of-2 FET multiplexer/demultiplexer and high-bandwidth bus switch manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and supports data I/O voltages from 0 V to 10 V. The device features a propagation delay of 3 ns, an ON-state resistance (ron) typically ranging from 3 Ω to 12.5 Ω depending on conditions, and low input/output capacitance with a maximum of 20 pF for the B port in the OFF state. It utilizes a charge pump to elevate gate voltage, ensuring flat ON-state resistance characteristics over the operating range. The component is housed in a TSSOP-16 package and functions across an operating temperature range of -40°C to +85°C.

Feature Summary

• Utilizes a charge pump architecture to provide low and flat ON-state resistance for minimal propagation delay and rail-to-rail switching capability.
• Features low input/output capacitance to minimize capacitive loading and signal distortion on the data bus.
• Supports bidirectional data flow with near-zero distortion signal gating and includes isolation during power-off via Ioff circuitry.

Applications

• PCI interface systems
• Memory interleaving circuits
• Bus isolation applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm packaging type and moisture sensitivity level. Ensure the procurement matches the required tape and reel or tube configuration as specified in the latest package addendum. Confirm RoHS compliance status and lead finish details directly from the official datasheet before finalizing orders.

Selection Notes

Select this component for high-bandwidth applications requiring precise signal routing between digital and analog domains. Consider the 4.75 V to 5.25 V supply requirement and the 0 V to 10 V I/O voltage range when designing the system interface. Evaluate the thermal impedance and package constraints to ensure adequate heat dissipation within the specified -40°C to +85°C operating temperature range.

Part Context

The TS5N412 belongs to the TS5N412 series of logic ICs, specifically categorized under encoders, decoders, multiplexers, and demultiplexers. It is designed to support broadband communications, networking, and data-intensive computing systems. The device provides an optimized interface solution for high-speed data transfer environments where low distortion and high isolation are critical requirements.

Replacement Considerations

The TS5N412DBQR is a functionally equivalent part number within the same family, differing primarily in its SSOP (DBQ) package and tape-and-reel shipping format instead of the TSSOP tube packaging.

FAQ
