Overview
The DM74ALS240AWM is an octal 3-STATE bus driver manufactured by onsemi, utilizing the Advanced Low Power Oxide-isolated Ion-implanted Schottky (ALS) TTL process. It operates within a supply voltage range of 4.5V to 5.5V and supports a free-air operating temperature from 0°C to +70°C. The device features low level drive current capability of 24mA and includes PNP input design to reduce input loading. It provides flexible bus interface implementation for memory, microprocessor, or communication systems with outputs organized into two separate groups of four buffers.
Feature Summary
- Advanced oxide-isolated ion-implanted Schottky TTL process
- Functional and pin compatible with DM74LS counterparts
- Improved switching performance with less power dissipation compared to DM74LS
- Switching response specified into 500Ω and 50pF load
Applications
- Memory system bus interfaces
- Microprocessor system bus interfaces
- Communication system bus interfaces
Procurement Notes
Verify component authenticity through authorized distribution channels. Confirm package integrity upon receipt. Ensure proper ESD handling procedures are followed during storage and assembly. Check datasheet revisions for any updates to electrical characteristics or mechanical dimensions before finalizing designs.
Selection Notes
Select this component when designing systems requiring octal bus drivers with 3-STATE output control. Consider its compatibility with DM74LS logic families for direct replacement scenarios. Evaluate thermal resistance requirements based on the specific package type chosen for the application environment.
Part Context
This part belongs to the DM74ALS240A/DM74ALS241A family of Octal 3-STATE Bus Drivers. It is designed to provide designers with flexibility in implementing bus interfaces. The device maintains buffer outputs in 3-STATE during power supply ramp-up or ramp-down to eliminate bus glitching problems.
Replacement Considerations
SN74ALS240A-1N and SN74ALS240AN are listed as parameter equivalent replacements.
