The SN74ALS244BDWR is an octal buffer and line driver manufactured by Texas Instruments, belonging to the Advanced Low-Power Schottky (ALS) logic family. It features eight non-inverting inputs driving three-state outputs, controlled by a single enable input. The device operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical characteristics include a high-level output current of -15 mA and a low-level output current of 48 mA. It functions reliably across a commercial temperature range from 0°C to +70°C.
Verify the specific suffix 'B' against official Texas Instruments documentation to confirm package type and temperature rating variations. Ensure the ordering part number matches the required RoHS compliance status and tape-and-reel specifications. Cross-reference the manufacturer's latest datasheet revision to validate pinout compatibility and recommended operating conditions before finalizing procurement orders.
Select this component when designing systems requiring moderate propagation delay with higher drive strength compared to standard LS logic. The ALS series offers a balance between power consumption and switching speed suitable for general-purpose digital applications. Consider the SOIC-20 package constraints and thermal dissipation requirements relative to the total static and dynamic current consumption during operation.
This component is part of the broader SN74ALS244 family of octal buffers. It shares functional similarities with other variants such as the SN74ALS244CDWR but may differ in specific manufacturing lot codes or packaging configurations. It serves as a fundamental building block for digital signal routing in legacy and industrial control systems utilizing 5V logic standards.
Compatible substitutes include the SN74ALS244CDWR and SN74ALS244DWRE4. Verify that alternative parts maintain identical pin assignments and electrical parameters to ensure direct replacement without circuit modification.
