TPIC6273DWG4

Overview

The TPIC6273DWG4 is an octal D-type latch manufactured by Texas Instruments, designed for power logic applications. It features eight D-type latches with a single data input and eight parallel outputs. The device operates within a supply voltage range of 4.5V to 5.5V and supports a maximum clock frequency of 30MHz. It utilizes a 20-pin Small Outline Integrated Circuit (SOIC) package with a width of 7.5mm. The component includes internal clamp diodes on all inputs to suppress transient voltages exceeding the supply rails.

Feature Summary

• Octal configuration providing eight independent D-type latches in a single package
• Power logic design capable of driving high-current loads directly
• Internal input clamp diodes protect against transient voltage excursions beyond supply rails

Applications

• Parallel output buffering for microprocessor systems
• Driving high-current loads such as relays or lamps
• General-purpose memory storage in digital circuits

Procurement Notes

Verify the specific suffix G4 indicates lead-free packaging compliant with RoHS standards. Confirm the SOIC-20 package dimensions match the target PCB footprint. Ensure the operating temperature range meets system requirements. Cross-reference the datasheet revision date to confirm electrical characteristics have not changed from previous versions.

Selection Notes

Select this component when an octal latch with direct load-driving capability is required. It serves as a suitable replacement for standard logic latches where higher output current is necessary without external drivers. Consider the 30MHz clock speed limit for high-frequency applications. Verify that the 4.5V minimum supply voltage aligns with the system power architecture.

Part Context

This part belongs to the TPIC6273 family of power logic octal D-type latches. It is functionally similar to the TPIC6273DW but includes the G4 suffix denoting environmental compliance. The device integrates power switching capabilities into standard logic latch functionality, reducing the need for separate driver components in load control applications.

Replacement Considerations

Direct substitutes include the TPIC6273DW and TPIC6273DWRG4. These parts share identical pinouts and logical functions. Verify that alternative packages maintain the same thermal and electrical performance specifications.
