Overview
The STP16C596TTR is a monolithic, medium-voltage, low-current power 16-bit shift register designed for LED panel displays. It contains a 16-bit serial input shift register with parallel output latches and constant current sinks. The device operates within a supply voltage range of 3V to 3.6V and supports a clock frequency up to 25MHz. Each channel provides a linear output current capability of 90mA. It is housed in a 16-TSSOP surface-mount package and functions as an LED driver IC with internal switches.
Feature Summary
- Integrates a 16-bit serial input shift register with parallel output latches for efficient data handling.
- Provides constant current sink outputs suitable for driving LED panel displays.
- Features linear output current control for consistent brightness regulation.
Applications
- LED panel displays
- Low current power shift register circuits
- Medium-voltage LED driver systems
Procurement Notes
Verify the specific suffix 'TTR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 16-TSSOP footprint matches the target PCB design constraints. Ensure compatibility with the specified 3V to 3.6V operating voltage range for the application environment.
Selection Notes
Select this component when a 16-bit shift register with integrated constant current sinking is required for LED applications. The 90mA per channel rating suits medium-brightness display needs. The TSSOP-16 package offers a compact solution for space-constrained designs requiring serial-to-parallel conversion with direct LED drive capability.
Part Context
This part belongs to the STP16CL596 family of LED drivers from STMicroelectronics. It shares architectural similarities with variants like the STP16C596A but differs in specific electrical ratings and packaging configurations. The series is characterized by its integration of shift register logic and power output stages in a single monolithic structure.
Replacement Considerations
Check for pin-compatible alternatives within the same product family, such as the STP16C596A or STP16C596B1R, ensuring their electrical specifications match the 90mA output requirement and 16-TSSOP package constraint.
