HCTS541DMSR

Overview

The HCTS541DMSR is an 8-bit bus driver from the HCT series, manufactured by Renesas Electronics Corporation. It features true outputs and operates within a supply voltage range of 2.0V to 6.0V, with a maximum operating temperature of 125°C and a minimum of -55°C. The device utilizes a ceramic DIP-20 package with side brazed construction. It has a load capacitance of 50 pF and employs low-enable control logic.

Feature Summary

• Provides 8-bit bus driving capability with true output configuration
• Constructed in a robust ceramic DIP-20 package suitable for high-temperature environments
• Compatible with standard HCT logic family specifications

Applications

• High-temperature industrial control systems requiring ceramic packaging
• Bus interface circuits in legacy or specialized computing hardware
• Signal buffering applications in aerospace or military-grade electronics

Procurement Notes

Verify the specific suffix code against official Renesas documentation to confirm pinout and electrical characteristics. Ensure the ceramic DIP-20 package matches the target board layout requirements. Confirm RoHS compliance status if required by current manufacturing standards. Check for obsolescence notices as this component may be discontinued.

Selection Notes

Select this component when a ceramic DIP package is mandatory for thermal or mechanical reliability. The HCT series compatibility ensures interoperability with other standard logic devices. Consider the wide operating temperature range for harsh environment deployments. Verify that the 8-bit width meets the system data bus requirements without additional multiplexing.

Part Context

This part belongs to the HCT logic family, designed for high-speed CMOS operation with TTL-compatible inputs. The SuperH microcontroller ecosystem often utilizes such logic components for peripheral interfacing. Ceramic packages are typically reserved for applications where plastic packages cannot withstand processing temperatures or environmental stresses.

Replacement Considerations

Consult Renesas datasheets for direct equivalents within the HCT series. Verify pin compatibility before substituting with generic 74HCT541 variants. Ensure the replacement supports the required ceramic DIP-20 form factor.
