STP16CL596MTR

Overview

The STP16CL596MTR is a 16-bit LED display driver manufactured by STMicroelectronics, designed for serial-to-parallel data conversion and constant current sinking. It operates within a supply voltage range of 3 V to 3.6 V and draws a maximum power supply current of 14.1 mA. The device provides regulated output currents of 1 mA at both high and low logic levels. It supports serial and parallel interface types and functions reliably across an operating temperature range from -40 °C to +125 °C. The component is housed in a SOIC-24 surface-mount package.

Feature Summary

• Provides 16-bit serial-in, parallel-out shift register functionality with D-type storage for LED panel displays
• Features regulated constant current sinks delivering 1 mA output current per channel
• Supports operation with standard 3.3 V microcontrollers via compatible voltage supply range
• Designed for high-speed data transmission suitable for LED matrix applications

Applications

• LED panel displays requiring 16-bit sink drive capability
• Digital signage systems utilizing serial data interfaces
• Electronic displays interfacing directly with 3.3 V microcontrollers
• Consumer electronics featuring segmented or dot-matrix LED indicators

Procurement Notes

Verify the specific suffix 'MTR' indicates tape-and-reel packaging rather than tube configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation as availability varies. Ensure the design accommodates the 3.6 V maximum supply limit. Check for obsolescence notices as this part number may be discontinued or superseded by newer series variants in the STP16 family.

Selection Notes

Select this component when a 1 mA constant current sink is required for low-power LED indicators. It is suitable for designs needing serial data expansion without additional external logic gates. Consider the SOIC-24 package constraints for PCB layout. Verify that the 3.3 V logic level compatibility meets the system's microcontroller requirements. This driver lacks error detection features found in other STP16 variants like the DPS05 series.

Part Context

This device belongs to the STP16CL596 series of LED display drivers. It serves as a monolithic solution for converting serial data into parallel outputs for driving LEDs. The series is characterized by low voltage operation and compatibility with standard digital logic families. It represents a specialized class of shift registers optimized for display applications rather than general-purpose data transfer.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The STP16DPS05 offers similar functionality but includes open/short circuit detection and higher current capabilities. Designers should verify pinout compatibility before substituting with other members of the STP16 family.
