Overview
The STP16CPC26TTR, produced by STMicroelectronics, is a monolithic, low voltage, 16-bit constant current LED sink driver. This device integrates a 16-bit shift register and data latches, which convert serial input data into parallel output format. It is designed to drive LEDs with constant current, adjustable through an external resistor, and supports output currents ranging from 5 mA to 90 mA. The device is suitable for high data rate transmission with a maximum clock frequency of 30 MHz and features thermal shutdown for overtemperature protection.
