SN74ALS241CDWR

Overview

The SN74ALS241CDWR is an octal buffer and line driver from the Texas Instruments ALS logic family, housed in a 20-pin SOIC package. It features non-inverting outputs with three-state capability controlled by separate output enable inputs. The device operates on a single 5V supply, typically between 4.75V and 5.25V. Key electrical characteristics include a low-level output current of 48mA and a high-level output current of -15mA. Propagation delay is specified at 10ns, with a maximum operating temperature range extending to +70°C.

Feature Summary

• Provides eight non-inverting buffered channels for signal transmission
• Features independent active-low and active-high output enable controls for bus management
• Delivers high drive strength suitable for driving capacitive loads

Applications

• Memory address drivers
• Clock drivers
• Bus-oriented architectures

Procurement Notes

Verify the specific suffix 'CDWR' against the manufacturer's official datasheet to confirm the exact temperature grade and tape-and-reel packaging specifications. Ensure the component matches the required SOIC-20 footprint and pinout configuration for your PCB design. Cross-reference the ALS series electrical limits with your system voltage requirements before finalizing procurement.

Selection Notes

Select this component when designing systems requiring moderate speed and high drive capability within the standard 5V logic environment. The ALS technology offers a balance between power consumption and switching speed compared to older TTL families. Consider the three-state functionality for implementing shared data buses where multiple devices must connect to a common line without interference.

Part Context

This part belongs to the SN74ALS (Advanced Low-power Schottky) family, which succeeded the standard SN74S series. It provides improved power-delay product characteristics while maintaining compatibility with existing TTL logic levels. The octal configuration allows for efficient handling of wide data paths in digital systems.

Replacement Considerations

Compatible substitutes include the SN74ALS241DR and SN74ALS241N. Verify that alternative packages maintain the same pinout and electrical performance parameters.
