STP16C596AB1R

Overview

The STP16C596AB1R is a monolithic LED display driver manufactured by STMicroelectronics. It integrates a 16-bit serial-in, parallel-out shift register and a 16-bit D-type storage register to control sixteen constant current sink outputs. The device operates with a supply voltage range of 3 V to 3.6 V and supports serial and parallel interface types. It is housed in an SOIC-24 package and functions within a temperature range of -40 °C to +125 °C. The component draws a maximum power supply current of 14.1 mA and provides output currents of 1 mA at high level and -1 mA at low level.

Feature Summary

• Integrates 16-bit shift and storage registers for serial-to-parallel data conversion
• Provides regulated constant current sinking for LED drive applications
• Supports bidirectional serial and parallel interface communication
• Includes thermal protection mechanisms for overtemperature safety

Applications

• LED panel displays
• Segmented LED indicators
• Low-voltage digital display systems

Procurement Notes

Verify the specific suffix 'AB1R' against official STMicroelectronics documentation to confirm tape-and-reel packaging and exact electrical tolerances. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary. Ensure the SOIC-24 package footprint matches the target PCB design requirements before finalizing procurement orders.

Selection Notes

Select this component when designing low-voltage LED drivers requiring integrated shift register functionality without external logic. The 3.3 V compatible supply range suits microcontroller interfaces. Consider the SOIC-24 package for surface-mount assembly. Verify that the 1 mA output current meets the specific LED brightness requirements, as higher current variants exist in the same family.

Part Context

This part belongs to the STP16CL596 series of LED display drivers from STMicroelectronics. The series is designed for driving segmented LEDs and matrix displays using minimal control lines. The device simplifies circuit design by combining data latching and current regulation in a single IC, reducing component count compared to discrete solutions.

Replacement Considerations

The STP16DPS05 and STAP16DPS05 are backward compatible alternatives offering higher current capabilities (up to 100 mA) and diagnostic features. These replacements maintain pin compatibility but require verification of current drive requirements and thermal management strategies due to increased power dissipation.
