DS3892N

Overview

The DS3892N is an octal trapezoidal repeater manufactured by National Semiconductor, now part of Texas Instruments. It is housed in a 20-pin plastic dual in-line package (PDIP-20). The device functions as a line receiver compatible with ALS-TTL logic families. It supports single-ended input configurations and provides eight independent channels for signal buffering and re-driving within digital circuits.

Feature Summary

• Provides octal buffering capability for simultaneous multi-channel signal processing
• Compatible with ALS-TTL logic standards for system integration
• Supports single-ended input interface requirements

Applications

• Digital signal line buffering in computer systems
• TTL logic level translation interfaces
• Octal data bus repeater applications

Part Context

This component belongs to the family of octal bus transceivers and repeaters produced by National Semiconductor. It serves as a legacy interface solution for systems requiring multiple buffered outputs from a single source. The device represents standard TTL-compatible buffering technology used in older industrial and computing hardware architectures.

Replacement Considerations

Verify compatibility with equivalent octal receivers such as the SN54ALS125 or SN74ALS125. Ensure the replacement supports single-ended inputs and matches the 20-pin DIP footprint. Confirm that the substitute device meets the specific voltage levels required by the ALS-TTL logic family.
