SN74FB2041ARCG3

Specialty Logic Overview

The SN74FB2041ARCG3 is a 7-bit TTL/BTL transceiver designed for signal translation between TTL and backplane transceiver logic (BTL) environments. It complies with IEEE Std 1194.1-1991. The device features open-collector B-port outputs capable of sinking 100 mA, while the A port operates at TTL levels. It includes a BIAS VCC pin to minimize signal distortion during live insertion or withdrawal. The component ensures a high-impedance state during power-up and power-down cycles.

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
• Maintains high-impedance state during power-up and power-down

Specialty Logic Applications

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

Specialty Logic Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature range. Confirm compliance with current environmental directives such as RoHS. Ensure the design accommodates the open-collector nature of the B-port outputs and provides appropriate external pull-up resistors if necessary for the target application voltage levels.

Specialty Logic Selection Notes

Select this component when interfacing TTL logic with BTL backplane standards. Consider the 100 mA sink capability of the B-port outputs for driving heavy loads. Verify that the operating temperature range meets system requirements. Note that TMS, TCK, TDI, and TDO pins are nonfunctional and should not be utilized for JTAG operations.

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 and specialized backplane transceiver logic requirements. The device supports split input and output pins on the A port and utilizes two separate output enables for the B port.
