TPIC6B273DWG4

Overview

The TPIC6B273DWG4 is an octal D-type latch manufactured by Texas Instruments, housed in a 20-pin SOIC surface-mount package. It operates with a supply voltage range of 4.5 V to 5.5 V and features high-current outputs capable of sourcing up to 150 mA per pin. The device utilizes positive edge-triggered logic for data latching and includes built-in clamp diodes on all inputs to handle fast-rising signals. Designed for robust performance, it supports operating temperatures from -40 °C to +85 °C.

Feature Summary

• High-output current capability of 150 mA per channel
• Positive edge-triggered octal D-type latch architecture
• Integrated input clamp diodes for signal protection

Applications

• High-current LED matrix displays
• Industrial relay driver circuits
• Motor control interface modules

Procurement Notes

Verify the presence of the G4 suffix to confirm lead-free compliance and RoHS adherence. Ensure the SOIC-20 package variant matches the required PCB footprint. Confirm that the specified temperature range meets the operational environment requirements. Cross-reference the manufacturer part number against authorized distributor lists to ensure authenticity.

Selection Notes

Select this component when high drive current is required for direct load interfacing without external transistors. The positive edge-triggered design suits synchronous digital systems requiring precise timing control. Verify that the 5V logic compatibility aligns with the system's microcontroller or processor output levels.

Part Context

This part belongs to the TPIC6B series of octal latches designed for high-current applications. It serves as a bridge between low-power logic circuits and high-power loads. The device integrates protection features to enhance reliability in noisy industrial environments.

Replacement Considerations

Check for equivalent parts within the same high-current latch family. Verify pinout compatibility before substituting with other manufacturers' offerings.
