SN74ALS244C-1DW

Overview

The SN74ALS244C-1DW is an octal buffer and line driver featuring three-state outputs, manufactured by Texas Instruments. It belongs to the ALS logic series and operates with a supply voltage range of 4.75 V to 5.25 V. The device provides eight non-inverting input lines and eight corresponding output lines within a 20-pin SOIC package. Key electrical characteristics include a high-level output current of -15 mA and a low-level output current of 48 mA. Static current consumption is specified at 9 mA, while operating power supply current reaches 17 mA. The component supports a wide operating temperature range from 0°C to +70°C.

Feature Summary

• Provides octal buffering and line driving capabilities with three-state output control for bus-oriented communication systems.
• Features non-inverting logic polarity to maintain signal integrity across eight independent channels.
• Designed with ALS technology to deliver high-speed performance suitable for demanding digital applications.

Applications

• Bus-oriented memory and address drivers
• Clock drivers and buffer circuits
• Multiplexer receivers

Procurement Notes

Verify the specific suffix 'C-1' against the manufacturer's official documentation to confirm pinout compatibility and functional equivalence. Ensure the SOIC-20 package dimensions match your PCB footprint requirements. Confirm that the operating temperature range of 0°C to +70°C meets your environmental specifications before finalizing procurement decisions.

Selection Notes

Select this component when designing systems requiring octal buffering with three-state outputs in a compact surface-mount package. The ALS logic family offers a balance of speed and power consumption. Consider the 4.75 V to 5.25 V supply voltage constraint and ensure your system design accommodates the specified static and operating current levels for proper thermal management.

Part Context

This part is part of the SN74ALS244 family of octal buffers and line drivers. It shares functional similarities with other devices in the 74ALS series but is distinguished by its specific packaging and suffix variations. The device serves as a critical interface component in digital logic designs, facilitating signal transmission between different circuit blocks while providing isolation through three-state outputs.

Replacement Considerations

SN74ALS244CDWR is a documented equivalent variant with identical functionality in a tape-and-reel package format.
