Overview
The DM74ALS241AN is an octal 3-STATE bus driver manufactured by onsemi, utilizing the Advanced Low-Power Schottky (ALS) logic family. It features non-inverting outputs controlled by two separate enable inputs, 1G and 2G. The device operates within a supply voltage range of 4.5V to 5.5V and supports a low-level output drive current of 24mA. It is housed in a 20-Lead Plastic Dual-In-Line Package (PDIP).
Feature Summary
- Octal 3-STATE Bus Driver with complementary enable gating for flexible bus interface implementation.
- Advanced low power oxide-isolated ion-implanted Schottky TTL process for improved switching performance.
- Functional and pin compatible with the DM74LS counterpart.
- Maintains buffer outputs in high impedance state during power supply ramp-up or ramp-down.
Applications
- Bus interface implementation with memory systems.
- Bus interface implementation with microprocessor systems.
- Bus interface implementation with communication systems.
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package type matches the 20-Lead PDIP specification. Check datasheet revision status as the product may be obsolete. Ensure environmental compliance requirements are met before integration into final designs.
Selection Notes
Select this component when designing systems requiring octal buffering with 3-STATE control. It serves as a functional replacement for DM74LS241 variants while offering lower power dissipation. Verify that the operating temperature range of 0°C to +70°C aligns with system thermal constraints.
Part Context
This part belongs to the DM74ALS240A/DM74ALS241A series of Octal 3-STATE Bus Drivers. The ALS series provides enhanced speed-to-power ratios compared to standard LS logic. The specific 'AN' suffix denotes the 20-Lead Plastic Dual-In-Line Package configuration.

FAQ
How does the DM74ALS241A handle power supply transitions?
The 3-STATE circuitry maintains the buffer outputs in a high impedance state during power supply ramp-up or ramp-down to eliminate bus glitching problems.
What is the relationship between DM74ALS241A and DM74LS241?
The DM74ALS241A is functionally and pin compatible with the DM74LS241 counterpart but offers improved switching performance with less power dissipation.
