MC74ACT244NG

Overview

The MC74ACT244NG is an octal buffer and line driver manufactured by onsemi, belonging to the 74ACT logic series. It features non-inverting outputs with three-state capability, designed for memory address driving, clock distribution, and bus-oriented transmission. The device operates within a supply voltage range of 4.5 V to 5.5 V. It provides high drive strength with output currents of 24 mA source and sink. The component utilizes a 20-pin SOIC package and supports surface mount installation.

Feature Summary

Octal buffer and line driver configuration with three-state outputs
TTL-compatible inputs for improved noise margin
High drive capability sourcing and sinking 24 mA

Applications

Memory address drivers
Clock drivers
Bus oriented transmitter/receiver applications

Procurement Notes

Verify the specific suffix 'NG' against official onsemi documentation to confirm package type and tape-and-reel specifications. Ensure the ordering part number matches the required RoHS compliance status and humidity sensitivity level. Cross-reference the datasheet revision date to confirm electrical characteristics align with current design requirements before procurement.

Selection Notes

Select this component when an octal buffer with TTL-compatible inputs is required in a 5V CMOS system. The 74ACT series offers faster switching speeds compared to standard 74LS devices while maintaining compatible input thresholds. Consider the 20-pin SOIC package constraints and thermal dissipation capabilities for the specific PCB layout environment.

Part Context

This part belongs to the MC74ACT244 family of octal buffers. Variants such as MC74ACT244DTR2G share similar functional characteristics but may differ in packaging or reel quantities. The MC74AC244 represents the AC series counterpart with different speed and power characteristics compared to the ACT series.

Replacement Considerations

Public confirmed substitute part numbers include MC74ACT244DTR2G and MC74ACT244DWG. Verify pinout compatibility and electrical parameters before substitution.
