54F652SDM

Overview

The 54F652SDM is an octal bidirectional transceiver manufactured by National Semiconductor, belonging to the 54F logic family. It integrates an 8-bit parity generator and checker with tri-state outputs for data integrity verification. The device supports bidirectional data transfer between two buses, controlled by a direction signal. Tri-state capability allows connection to multiple transceivers on a common bus without electrical conflict. The component is designed for high-speed digital applications requiring reliable data transmission and error checking capabilities in military or industrial environments.

Feature Summary

• Octal bidirectional data transceiver functionality
• Integrated 8-bit parity generator and checker
• Tri-state output control for bus isolation

Applications

• High-speed data bus interfaces
• Memory systems requiring parity checking
• Military-grade digital communication links

Procurement Notes

Verify manufacturer status as National Semiconductor was acquired by Texas Instruments. Confirm availability of original NS stock versus TI equivalents. Check for obsolescence notices or lifecycle status updates. Ensure package type matches design requirements. Validate authenticity through authorized distribution channels.

Selection Notes

Select this component when bidirectional octal transfer with built-in parity is required. Consider compatibility with 54F logic voltage levels. Evaluate tri-state buffering needs for system architecture. Assess environmental ratings for specific deployment conditions. Compare against newer generations for performance improvements.

Part Context

This part belongs to the standard 54F series of high-speed logic devices. It serves as a bridge between different logic domains or memory banks. The inclusion of parity logic simplifies system design by reducing external component count. It represents a legacy solution for robust digital data handling in critical applications.

Replacement Considerations

Consider SN74F652 equivalents from Texas Instruments. Verify pinout compatibility before substitution. Check if updated versions offer improved speed or lower power consumption.
