SN74FB2031RCG3

Specialty Logic Overview

The SN74FB2031RCG3 is a 9-bit TTL/BTL transceiver/translator from the Texas Instruments 74FB series. It operates within a supply voltage range of 4.5 V to 5.5 V and supports bidirectional data transfer. The device features a propagation delay of 7 ns and an on-delay time of 7.8 ns, with a maximum operating frequency of 150 MHz. It provides high output drive capabilities, delivering up to 100 mA low-level current and -32 mA high-level current. Packaged in a 52-pin QFP (10x10 mm) with 0.65 mm terminal spacing, it functions within an industrial temperature range of 0°C to 70°C.

Specialty Logic Feature Summary

Specialty Logic Procurement Notes

Verify the specific suffix 'RCG3' against official Texas Instruments documentation to confirm package type and compliance status. Ensure compatibility with existing PCB footprints for the 52-QFP configuration. Check for any lifecycle changes or obsolescence notices directly from the manufacturer before procurement planning.

Specialty Logic Selection Notes

Select this component when bidirectional translation between TTL and BTL standards is required for 9-bit wide buses. Consider the 52-QFP package constraints and 0.65 mm pitch requirements for board layout. Verify that the 4.5 V to 5.5 V supply range aligns with the system power architecture and that the 150 MHz speed meets the application timing needs.

Specialty Logic Part Context

This part belongs to the Texas Instruments 74FB series of specialty logic ICs. It is categorized under interface ICs and transceivers. The device is designed for applications requiring fast switching speeds and reliable level shifting between different logic families, specifically targeting high-performance digital communication interfaces.

Specialty Logic Replacement Considerations

Check for direct substitutes within the 74FB series with identical pinouts and electrical characteristics. Verify if alternative packages like RCRG3 are functionally equivalent but differ only in packaging details.
