Overview
The STP16CL596TTR is an 8-bit LED display driver manufactured by STMicroelectronics. It features a serial shift register topology with linear output regulation. The device operates within a supply voltage range of 3V to 3.6V and supports output voltages up to 16V. Each channel provides a maximum output current of 90mA, suitable for direct LED driving. The component is housed in a 16-TSSOP surface-mount package and functions reliably across an operating temperature range of -40°C to +125°C.
Feature Summary
- Integrates an 8-channel linear LED driver with internal shift register functionality
- Supports high-speed serial data input at frequencies up to 25MHz
- Provides robust thermal performance with extended industrial temperature ratings
Applications
- LED matrix displays
- Numeric LED indicators
- Seven-segment display modules
Procurement Notes
Verify the specific suffix 'TTR' to confirm tape-and-reel packaging configuration. Ensure compatibility with existing 3.3V logic levels. Confirm availability status as this series may be subject to discontinuation or lifecycle changes. Validate pinout alignment with current PCB layouts before finalizing procurement orders.
Selection Notes
Select this component when an 8-channel constant-current sink is required for low-voltage LED applications. The integrated shift register simplifies microcontroller interface requirements. Consider the 16-TSSOP footprint constraints during mechanical design. Evaluate the 90mA per-channel limit against total power dissipation requirements for dense display arrays.
Part Context
This part belongs to the STP08/STP16 family of LED drivers from STMicroelectronics. These devices are designed for simple serial control of LED segments. The CL variant typically denotes specific current characteristics and package options within the broader product line, focusing on cost-effective solutions for standard display applications.
Replacement Considerations
Public confirmed substitute part numbers: STP08CL596TTR (8-bit variant), STP16CL596M (Tube package variant). Verify electrical parameters and pin compatibility before substitution.
