SN74FB2033ARCRG3

Specialty Logic Overview

The SN74FB2033ARCRG3 is an 8-bit TTL/BTL register transceiver manufactured by Texas Instruments. It features a B port with open-drain outputs capable of absorbing 100 mA, designed for backplane transceiver logic (BTL) signal levels compatible with IEEE Std 1194.1-1991. The A port utilizes separated input and output buses for LVTTL logic levels. The device supports configurable data flow through buffer, D-type flip-flop, or D-type latch modes, controlled by mode inputs. It includes a BIAS(VCC) pin to minimize signal distortion during hot-swap operations and ensures high-impedance states during power-up or power-down sequences.

Specialty Logic Feature Summary

• High-drive capability with B port open-drain outputs absorbing 100 mA for heavy backplane loads
• BIAS(VCC) pin functionality minimizes signal distortion during hot-swap events
• Separated A port input and output buses provide feedback paths for control and diagnostic monitoring
• Configurable data flow supports buffer, D-type flip-flop, and D-type latch operational modes

Specialty Logic Applications

• Backplane interface connections between cards operating at LVTTL logic levels and backplanes using BTL signal levels
• Systems requiring IEEE Std 1194.1-1991 (BTL) standard compatibility
• Hot-swap applications utilizing the BIAS(VCC) feature for signal integrity maintenance

Specialty Logic Procurement Notes

Verify the specific suffix 'RG3' against official documentation to confirm package type and environmental compliance details. Ensure the ordering part number matches the exact configuration required for your design, as suffixes can indicate variations in tape-and-reel specifications or temperature ratings. Cross-reference the manufacturer's latest datasheet to validate availability and any potential product lifecycle changes before finalizing procurement plans.

Specialty Logic Selection Notes

Select this component when designing interfaces that require driving heavy backplane loads with high current absorption capabilities. It is suitable for systems needing flexible data path configurations via buffers or latches. Consider the BIAS(VCC) feature if the application involves hot-plugging components. Verify that the voltage requirements for the BTL and LVTTL ports align with the system's power supply rails and signal standards.

Specialty Logic Part Context

This device belongs to the SN74FB series of high-speed bus transceivers from Texas Instruments. It is functionally similar to the SN74GTLP2033 but operates with TTL/BTL signaling standards rather than GTLP. The SN74FB2033A variant shares core functionalities, including the 100 mA B port drive and hot-swap support. This specific part number represents the tape-and-reel version of the 8-bit register transceiver.

Specialty Logic Replacement Considerations

The SN74FB2033A is a functional equivalent within the same family. Check for direct cross-references in TI's replacement guides. Ensure substitute parts maintain the 100 mA B port current rating and BIAS(VCC) pin functionality if hot-swap support is required.
