MC74AC244M

Overview

The MC74AC244M is an octal buffer and line driver from the AC logic series, manufactured by onsemi. It features eight non-inverting channels with three-state outputs in a 20-pin plastic small outline (SOIC) surface-mount package. The device operates within a supply voltage range of 2V to 6V. Key electrical parameters include a maximum low-level output current of 24mA and a maximum high-level output current of -24mA. Propagation delay is specified at 9ns at 3.3V and 7ns at 5V. The component supports a wide operating temperature range from -40°C to +85°C.

Feature Summary

Provides eight independent non-inverting buffer channels for signal driving applications
Features three-state outputs allowing multiple drivers to share a bus without interference
Operates across a wide supply voltage range from 2V to 6V for flexible system integration

Applications

Memory module address and data bus buffering
Clock distribution networks requiring signal isolation
General-purpose digital signal routing in embedded systems

Procurement Notes

Verify the specific suffix 'M' against the manufacturer's official documentation to confirm the exact package variant and tape/reel specifications. Ensure the ordered part matches the required SOIC-20 form factor and lead finish. Cross-reference the full part number with the latest datasheet revision to confirm compliance with current RoHS and material composition declarations before finalizing procurement.

Selection Notes

Select this component when an octal buffer with three-state capability is required for 2V to 6V CMOS logic families. The AC series offers faster propagation delays compared to standard HC or HCT variants. Consider the SOIC-20 package constraints and thermal dissipation requirements for the target application environment. Verify input compatibility with the source logic family to ensure proper voltage level translation if interfacing with different logic standards.

Part Context

This component belongs to the MC74AC244 series of octal buffers and line drivers. It is part of onsemi's broader portfolio of AC logic integrated circuits designed for high-speed digital applications. The device serves as a fundamental building block for bus-oriented architectures in consumer electronics and industrial control systems where signal integrity and drive strength are critical.
