TIR1000IPWG4

Encoders, Decoders, Converters Overview

The TIR1000IPWG4 is a standalone Infrared Data Association (IrDA) encoder and decoder manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.5 V and supports UART bus compatibility. The device is housed in an 8-pin Thin Shrink Small Outline Package (TSSOP) with dimensions of 4.4 mm in length. It functions reliably across an extended industrial temperature range from -40 °C to +85 °C. The component is lead-free, RoHS compliant, and carries a Moisture Sensitivity Level (MSL) rating of 1, indicating unlimited exposure to floor life conditions.

Encoders, Decoders, Converters Feature Summary

• Provides standalone encoding and decoding for IrDA communication protocols without requiring external microcontrollers.
• Ensures electrical isolation between the host system and the infrared transceiver circuitry.
• Supports operation at both 3.3 V and 5 V supply voltages for flexible integration.

Encoders, Decoders, Converters Applications

• Serial port expansion modules requiring IrDA connectivity.
• Industrial control systems needing isolated infrared data links.
• Embedded devices integrating wireless serial communication capabilities.

Encoders, Decoders, Converters Procurement Notes

Verify the specific suffix 'G4' confirms lead-free and RoHS compliance status against current manufacturer documentation. Confirm the package designation matches the required 8-TSSOP footprint for PCB layout. Ensure the operating temperature grade meets the environmental requirements of the target application before finalizing procurement specifications.

Encoders, Decoders, Converters Selection Notes

Select this component when a dedicated, low-pin-count solution for IrDA signal conversion is required. Compare against the TIR1000IPW variant if reel packaging is preferred over tube packaging. Verify that the 2.7 V to 5.5 V input range aligns with the system's power rails. Consider the TIR1000PSR only if a wider commercial temperature range suffices for the design.

Encoders, Decoders, Converters Part Context

This part belongs to the TIR1000 family of standalone IrDA interface controllers. It serves as a bridge between UART-based digital logic and analog infrared optical signals. The device simplifies design by integrating necessary modulation and demodulation circuits into a single compact package, reducing board space compared to discrete solutions.

Encoders, Decoders, Converters Replacement Considerations

The TIR1000IPWR is a verified substitute offering identical functionality in a tape-and-reel package format. The TIR1000PSR provides similar features but is rated for a commercial temperature range of 0 °C to 70 °C rather than the industrial range of the IPWG4.
