CD74FCT541ATM96

Overview

The CD74FCT541ATM96 is an 8-bit buffer and driver manufactured by Harris Corporation, belonging to the FCT series. It features true output polarity and a 3-state output configuration controlled by a low-active enable signal. The device utilizes BICMOS technology and operates within a voltage range of 4.5V to 5.5V. It is housed in a 20-SOIC surface-mount package with a width of 0.295 inches (7.50mm). The component supports bidirectional data transfer and includes independent control for each direction.

Feature Summary

• Provides 8-bit buffering and driving capabilities with true output polarity
• Features 3-state outputs controlled by a low-active enable signal
• Utilizes BICMOS technology for high-speed performance
• Supports bidirectional data transfer with independent directional control

Applications

• High-speed bus architectures requiring 8-bit data transmission
• Memory interface circuits utilizing 3-state buffering
• System-level data routing with directional control requirements

Procurement Notes

Verify the manufacturer origin, as Harris Corporation assets were acquired by Renesas Electronics. Confirm RoHS compliance status, as original Harris versions may not meet current environmental standards. Ensure the 20-SOIC package dimensions match the 0.295-inch width specification. Validate the operating temperature range against system requirements. Check for availability from authorized distributors or surplus suppliers due to potential obsolescence.

Selection Notes

Select this component when an 8-bit buffer with true output and 3-state capability is required. The FCT series offers faster switching speeds compared to standard HCT logic. Ensure the design accommodates the 4.5V to 5.5V supply voltage range. Consider the 20-SOIC package for surface-mount assembly constraints. Verify that the low-active enable logic aligns with the system control signals.

Part Context

This part belongs to the CD74FCT family of high-speed CMOS logic devices originally developed by Harris Corporation. The FCT series is known for its compatibility with TTL inputs while offering CMOS noise immunity. The CD74FCT541 specifically denotes an octal buffer/driver with 3-state outputs. The 'TM' suffix indicates the SOIC package type, and '96' often refers to specific tape-and-reel packaging configurations.

Replacement Considerations

Check for equivalents from Renesas Electronics, which acquired Harris's logic product line. Verify pinout compatibility with other 8-bit bus transceivers in the FCT or HCT families. Ensure electrical characteristics such as output drive strength and propagation delay meet the application requirements before substitution.
