STPIC6D595B1R

Overview

The STPIC6D595B1R is a monolithic, medium-voltage, low-current power 8-bit shift register designed for systems requiring moderate load power. It integrates an 8-bit serial-in, parallel-out shift register feeding an 8-bit D-type storage register. The device features eight low-side open-drain DMOS transistor outputs with ratings of 20 V and 120 mA continuous sink-current capability. Each output provides a 250 mA maximum current limit at T C = 25 °C. Data transfers through the shift and storage registers via dedicated clock inputs, with cascading supported via a serial output port.

Procurement Notes

Verify the specific suffix B1R against official STMicroelectronics documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints by cross-referencing pin assignments with the standard STPIC6D595 variant. Confirm operating temperature range requirements align with the -40 °C to 125 °C specification before procurement.

Selection Notes

Select this component for designs requiring medium-voltage control of multiple loads with serial interface simplicity. The integrated DMOS outputs eliminate external driver transistors, reducing bill of materials. Consider the 20 V rating and 120 mA continuous current when sizing thermal management solutions for high-density layouts.
