TLC5921DAPRG4

Overview

The TLC5921DAPRG4 is a linear LED driver IC featuring 16 constant current sink outputs. It integrates a serial shift register and data latch for input data storage. The device supports a maximum data transfer rate of 20 MHz and operates within a supply voltage range of 4.5 V to 5.5 V. Each output channel provides up to 80 mA of drive current, with an output voltage capability of 17 V. It is housed in a 32-HTSSOP package and functions across a temperature range of -20°C to 85°C.

Feature Summary

Integrates a serial shift register and data latch for efficient data handling
Provides 16 independent constant current sink channels for LED control
Supports high-speed serial data transfer at up to 20 MHz

Applications

LED display systems requiring constant current regulation
General-purpose LED lighting applications
Portable electronic devices utilizing LED indicators

Procurement Notes

This component is officially classified as obsolete by Texas Instruments and is no longer in active production. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors or secondary market suppliers. Buyers must confirm the specific manufacturing date code and lot number to ensure component integrity, as availability is limited to existing inventory rather than new manufacturing runs.

Selection Notes

Engineers selecting this part should consider its obsolete status when designing new products. While it offers 16-channel linear drive capabilities, newer alternatives within the Texas Instruments portfolio may provide enhanced features or better long-term supply chain stability. Verify that the 80 mA per channel and 20 MHz interface speed meet the system requirements before committing to this legacy component for any design.

Part Context

The TLC5921 belongs to a family of linear LED drivers designed for simple serial control interfaces. Unlike PWM-based drivers, it uses constant current sinks to regulate brightness. The DAPRG4 suffix indicates a tape and reel packaging format suitable for automated surface-mount assembly, distinguishing it from tube-packaged variants like the TLC5921DAP.
