TPIC6B273DWR

Overview

The TPIC6B273DWR is an octal D-type latch manufactured by Texas Instruments, designed for high-voltage and medium-current power applications. It features eight open-drain DMOS outputs capable of sinking up to 150 mA per channel with a maximum voltage rating of 50 V. The device includes built-in voltage clamping for inductive transient protection, making it suitable for driving relays, solenoids, and other loads. It operates on a single supply voltage ranging from 4.5 V to 5.5 V and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Octal D-type latch architecture with positive edge triggering
• Open-drain DMOS outputs rated for 50 V and 150 mA continuous sink current
• Integrated voltage clamping for inductive load transient protection

Applications

• Relay driver circuits
• Solenoid control systems
• High-side or low-side switching for medium-power loads

Procurement Notes

Verify the specific package marking and date code against the manufacturer's latest datasheet to ensure authenticity. Confirm that the ordering suffix matches the required tape-and-reel configuration for automated assembly processes. Cross-reference the component lot traceability with the supplier's certificate of conformity prior to final procurement approval.

Selection Notes

Select this component when an octal latch with high-voltage output capability is required. Ensure the application logic utilizes positive edge triggering compatible with standard CMOS levels. Verify that the thermal management design accommodates the junction temperature limits under maximum load conditions and ambient operating temperatures.

Part Context

This part belongs to the TPIC6B series of power shift registers and latches from Texas Instruments. These devices integrate standard logic input functionality with robust power output stages, simplifying the interface between low-voltage microcontrollers and higher-voltage industrial loads without requiring external discrete transistors.

Replacement Considerations

Check for direct pin-compatible alternatives such as the TPIC6B595 if serial data shifting is preferred over parallel latching. Verify electrical specifications match exactly, particularly the 50 V output rating and 150 mA current capacity, before substituting.
