DM74ALS244AWMX

Overview

The DM74ALS244AWMX is an octal 3-STATE bus driver manufactured by onsemi, utilizing the Advanced Low Power Schottky (ALS) process. It features a 20-Lead Small Outline Integrated Circuit (SOIC) package with JEDEC MS-013 dimensions and a 0.300-inch width. The device operates within a supply voltage range of 4.5V to 5.5V and supports an operating free-air temperature range of 0°C to +70°C. Propagation delay times are specified between 3ns and 10ns under standard load conditions.

Feature Summary

Provides flexible bus interface implementation for memory, microprocessor, or communication systems
Maintains buffer outputs in high impedance state during power supply ramp-up or ramp-down to eliminate bus glitching
Organized into two separate groups of four buffers with independent 3-STATE gating control inputs

Applications

Memory system bus interfaces
Microprocessor system data routing
Communication system signal buffering

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm that the specific ordering code matches the required package type and suffix specifications. Ensure compliance with RoHS directives if environmental standards are mandated for the target assembly process.

Selection Notes

Select this component when designing systems requiring octal bidirectional data transfer with controlled high-impedance states. Consider the ALS technology benefits regarding switching performance and power dissipation relative to legacy counterparts. Verify that the thermal characteristics of the SOIC package align with the system's heat dissipation requirements.

Part Context

This part belongs to the DM74ALS244A family of octal 3-STATE bus drivers. It is functionally and pin-compatible with the 74LS counterpart series. The device utilizes an advanced oxide-isolated ion-implanted Schottky TTL process to achieve improved switching response and reduced power consumption compared to standard Schottky logic families.
