SN74ALS244C-1NSR

Overview

The SN74ALS244C-1NSR 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 non-inverting polarity. The device is housed in a 20-pin SOIC package and supports surface-mount installation. It functions within a supply voltage range of 4.75 V to 5.25 V and maintains operation between 0°C and +70°C.

Feature Summary

• Provides eight independent buffering channels for signal distribution
• Features three-state outputs to enable bus-oriented systems
• Supports high-current low-level output drive capabilities

Applications

• Bus-oriented systems requiring signal isolation
• Memory address drivers for data buses
• Clock drivers and buffer circuits

Procurement Notes

Verify the specific suffix 'C-1' against official Texas Instruments documentation to confirm pinout and electrical characteristics match your design requirements. Ensure the NSR tape-and-reel packaging aligns with your automated assembly equipment specifications before finalizing procurement orders.

Selection Notes

Select this component when designing systems that require octal buffering with high-speed ALS performance levels. Consider the 20-SOIC package constraints and verify that the 5V logic family compatibility matches the rest of the circuit's voltage domains and interface standards.

Part Context

This part is part of the SN74ALS244 family of octal buffers. It shares functional similarities with other ALS series devices like the SN74ALS245 transceiver but lacks bidirectional capability. The device serves as a standard solution for driving multiple loads from a single source in digital logic applications.

Replacement Considerations

Public confirmed substitute part numbers include SN74ALS244CDWR and SN74ALS244CDWRE4. Verify package type and suffix variations when substituting to ensure mechanical and electrical compatibility.
