DM74AS760N

Overview

The DM74AS760N is an octal buffer and line driver from the AS logic series, manufactured by onsemi. It features eight non-inverting input lines driving corresponding outputs with open collector capability. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a low-level output current of 64 mA and a propagation delay of 18.5 ns. It is housed in a 20-pin PDIP package designed for through-hole mounting.

Feature Summary

• Provides buffering and line driving functions for digital signals
• Features open collector outputs for flexible interfacing
• Supports non-inverting signal transmission across eight channels

Applications

• High-speed data bus buffering
• Line termination and driving applications
• Digital signal interface circuits

Procurement Notes

Verify component authenticity against official datasheets due to potential variations in manufacturing sources. Confirm pinout compatibility with existing PCB layouts before integration. Check RoHS compliance status as required by specific project regulations. Ensure proper handling procedures are followed during installation to prevent electrostatic discharge damage to the bipolar logic components.

Selection Notes

Select this component when high drive strength is required for long traces or multiple loads. The open collector configuration allows for wired-OR connections and level shifting capabilities. Consider the bipolar technology characteristics regarding power consumption and speed trade-offs compared to CMOS alternatives. Verify that the operating temperature range meets environmental requirements.

Part Context

This part belongs to the SN74AS760 family of octal buffers. It shares functional similarities with other AS-series drivers but differs in specific output configurations. The DM prefix indicates onsemi manufacturing origin. It serves as a replacement for older National Semiconductor equivalents in legacy designs requiring robust signal integrity.

Replacement Considerations

SN74AS760AN is a parameter-equivalent alternative from Texas Instruments.
