STPIC6D595TTR

Overview

The STPIC6D595TTR is a monolithic, medium-voltage, low-current power 8-bit shift register designed for moderate load power applications. 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 a continuous sink-current capability of 120 mA and a maximum current limit of 250 mA at 25 °C case temperature. It operates over a case temperature range of -40 °C to 125 °C and provides up to 2.0 kV ESD protection via the human-body model.

Feature Summary

• Integrates an 8-bit serial-in, parallel-out shift register connected to an 8-bit D-type storage register for data latching.

Applications

• LED systems requiring moderate load power

Procurement Notes

Verify the specific suffix 'TTR' against official STMicroelectronics documentation to confirm tape-and-reel packaging specifications. Confirm that the part number corresponds to the active production status indicated in manufacturer catalogs. Ensure compatibility with existing footprints by checking mechanical dimensions against the STPIC6C595 footprint compatibility claim. Validate electrical ratings against system requirements before procurement.

Selection Notes

Select this component when designing systems requiring medium-voltage power switching with integrated shift register functionality. It is suitable for applications needing cascaded data transfer through the serial output port. Consider the 20 V output rating and 120 mA continuous sink capability for driving loads such as LEDs. Evaluate thermal performance given the current limit decreases as junction temperature increases.

Part Context

The STPIC6D595 belongs to the STPIC series of power logic devices from STMicroelectronics. It is distinct from standard logic shift registers like the M74HC595, offering integrated high-current DMOS outputs rather than just signal-level shifting. This integration simplifies designs by combining control logic and power driving stages in a single monolithic package.

Replacement Considerations

The device is footprint compatible with the STPIC6C595. Verify electrical parameters and pinout compatibility before substitution.
