SN74FB2041ARC

Specialty Logic Overview

The SN74FB2041ARC is a 7-bit TTL/BTL transceiver designed for signal translation between TTL and backplane transceiver logic (BTL) environments, compatible with IEEE Std 1194.1-1991. It operates at a supply voltage of 5V within a temperature range of 0°C to 70°C. The device features open-collector B-port outputs capable of sinking 100 mA and includes split input/output pins on the A port. It incorporates a BIAS VCC pin to minimize signal distortion during live insertion or withdrawal.

Specialty Logic Feature Summary

• Translates signals between TTL and backplane transceiver logic (BTL) environments
• Open-collector B-port outputs sink up to 100 mA
• BIAS VCC pin minimizes signal distortion during live insertion or withdrawal
• High-impedance state maintained during power-up and power-down

Specialty Logic Applications

• Backplane transceiver logic interfaces
• IEEE Std 1194.1-1991 compliant systems
• TTL to BTL signal translation

Specialty Logic Procurement Notes

Verify the specific ordering suffix 'RC' corresponds to the tube package variant when sourcing. Confirm RoHS compliance status by checking for the 'G3' suffix if lead-free components are required. Ensure the operating temperature range of 0°C to 70°C meets system requirements. Validate that the 52-pin QFP package dimensions align with PCB layout constraints.

Specialty Logic Selection Notes

Select this component for applications requiring direct interface between TTL logic and BTL backplane standards. The high current sinking capability of the B-port makes it suitable for driving heavy loads. Consider the split I/O structure of the A-port for complex routing needs. Verify that the specific enable/disable logic partitions match the control architecture of the target system.

Specialty Logic Part Context

This part belongs to the SN74FB2041A family of 7-bit TTL/BTL transceivers manufactured by Texas Instruments. It is specifically engineered to bridge the gap between standard TTL signaling levels and the distinct voltage requirements of backplane transceiver logic. The device supports high-speed data transfer while maintaining compatibility with industry-standard test bus protocols.

Specialty Logic Replacement Considerations

Check for SN74FB2041ARCR as an alternative reel-packaged version from the same manufacturer. Verify functional equivalence if considering cross-brand alternatives, ensuring BTL voltage levels and current sinking capabilities match.
