DM81LS95AN

Overview

The DM81LS95AN is a 3-STATE Octal Buffer manufactured by onsemi, utilizing low-power-Schottky TTL technology. It provides eight non-inverting buffers in a single package with common enable lines accessed through a 2-input NOR gate. The device operates within a supply voltage range of 4.75V to 5.25V and supports an operating temperature range of 0°C to +70°C. Key electrical characteristics include a HIGH Level Output Current of -5.2mA and a LOW Level Output Current of 24mA. Typical propagation delay is 15ns, with typical power dissipation at 80mW.

• Eight two-input buffers with common enable control via a 2-input NOR gate
• Non-inverting logic function presenting true data at outputs
• Outputs enter high-impedance state upon application of high logic level to enable pins

Applications

• Data bus buffering applications requiring controlled signal transmission
• Digital systems utilizing low-power-Schottky TTL logic families
• Circuit designs necessitating tri-state output isolation capabilities

Procurement Notes

Verify the specific ordering code suffix against manufacturer documentation to confirm package type and availability status. Confirm RoHS compliance requirements prior to procurement. Check for obsolete status or lifecycle notices as this component may be discontinued. Ensure the supplier source matches official distribution channels to guarantee authenticity.

Selection Notes

Select this component when designing circuits that require octal buffering with active-low enable controls. Consider the 20-PDIP package constraints for board layout. Evaluate the 15ns typical propagation delay against system timing requirements. Verify compatibility with existing low-power-Schottky TTL logic levels and voltage supplies.

Part Context

This part belongs to the 74LS series of standard logic integrated circuits. It is part of a family including the DM81LS96A (inverting) and DM81LS97A (dual enable). Manufactured originally by Fairchild Semiconductor, it is now distributed under the onsemi brand. The device serves as a fundamental building block for digital signal routing and isolation.

Replacement Considerations

Compatible substitutes include DM81LS96AN and DM81LS97AN from the same datasheet family. Verify pinout compatibility and logic inversion differences before substitution. Cross-reference with other manufacturers' 74LS95 equivalents ensuring identical package dimensions and electrical specifications.
