DM74ALS241AWMX

Overview

The DM74ALS241AWMX is an octal 3-STATE bus driver manufactured by onsemi, utilizing the Advanced Low Power Schottky (ALS) logic family. It operates within a supply voltage range of 4.5V to 5.5V and supports a low-level output current of 24mA and a high-level output current of -15mA. The device features two separate groups of four buffers with complementary enable gating. Propagation delay ranges from 3ns to 11ns depending on the transition direction. It is housed in a 20-Lead Small Outline Integrated Circuit (SOIC) package.

Feature Summary

• Octal 3-STATE bus driver architecture designed for memory, microprocessor, and communication systems
• Complementary enable gating controls two separate groups of four buffers
• Maintains buffer outputs in high impedance state during power supply ramp-up or ramp-down
• Compatible with TTL input levels and offers improved switching performance over LS counterparts

Applications

• Memory interface implementation
• Microprocessor system data buses
• Communication systems bus interfacing

Procurement Notes

Verify the specific ordering suffix 'X' indicates tape and reel packaging as per datasheet specifications. Confirm that the component falls under the DM74ALS241A series functional description. Ensure compatibility with existing 20-lead SOIC footprints. Check for RoHS compliance status if required by project standards. Validate that the manufacturer designation aligns with current onsemi product lines.

Selection Notes

Select this component when designing systems requiring bidirectional data transfer with high drive capability. The ALS technology provides a balance between speed and power consumption suitable for general digital logic applications. Consider the complementary enable inputs for complex bus arbitration schemes. Verify that the operating temperature range meets environmental requirements.

Part Context

This part belongs to the DM74ALS240A/DM74ALS241A Octal 3-STATE Bus Driver family. It shares the same physical dimensions and pinout as the non-inverting DM74ALS240A but utilizes complementary enable gating. The device is produced using an advanced low power oxide-isolated ion-implanted Schottky process.
