TPIC6B273DWRG4

Overview

The TPIC6B273DWRG4 is an octal D-type latch manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features high-current outputs capable of sourcing or sinking 150 mA. The device utilizes a positive edge-triggered clock mechanism and provides inverting logic polarity. It is housed in a 20-SOIC surface-mount package and supports operation across an extended temperature range from -40 °C to +125 °C.

Feature Summary

• Provides high-current drive capability with 150 mA output per pin for direct load control
• Features octal configuration with eight independent D-type latches in a single package
• Utilizes positive edge-triggered clocking for precise data capture timing

Applications

• Direct driving of high-power loads such as LEDs, lamps, and solenoids
• Industrial motor control systems requiring robust current handling
• Automotive lighting circuits and body electronics modules

Procurement Notes

Verify the specific suffix G4 indicates lead-free composition and RoHS compliance status according to manufacturer documentation. Confirm the SOIC-20 package dimensions match PCB footprint requirements. Ensure the operating voltage remains strictly within the 4.5 V to 5.5 V limits to prevent device damage. Check thermal dissipation capabilities for the intended application environment.

Selection Notes

Select this component when high-output current is required compared to standard logic families. The 150 mA capability eliminates the need for external driver transistors in many applications. Consider the inverting logic function during circuit design. Verify that the 5.5 V maximum supply voltage aligns with the system power rails.

Part Context

This part belongs to the TPIC6B series of high-current latch drivers designed for automotive and industrial environments. It integrates protection features typical of TI's automotive-grade logic products. The device serves as a bridge between low-voltage microcontrollers and high-power actuators.

Replacement Considerations

The SN74HC273QDWRG4Q1 is a related octal flip-flop but lacks the high-current output stage. Standard HC logic cannot replace this part for direct load driving due to significantly lower current ratings.
