74ACT244MSA

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ACT244MSA is an octal buffer and line driver featuring 3-state outputs, designed for memory address driving, clock distribution, and bus-oriented transmitter/receiver applications. It operates within a supply voltage range of 4.5V to 5.5V and utilizes ACT logic family characteristics, providing TTL-compatible inputs. The device offers high drive capability with outputs capable of sourcing and sinking 24mA. Packaged in a 20-pin SOIC (Small Outline Integrated Circuit) format, it supports surface-mount installation and functions reliably across an industrial temperature range from -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'MSA' against official onsemi documentation to confirm package dimensions and tape-and-reel specifications. Ensure the ordering part number matches the required moisture sensitivity level and RoHS compliance status for your manufacturing process. Cross-reference the datasheet revision date to confirm current electrical parameters before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring high-density octal buffering with TTL-compatible input thresholds. The 24mA drive strength makes it suitable for driving multiple loads or longer traces compared to standard AC logic. Consider the 20-pin SOIC package constraints regarding PCB space and thermal dissipation requirements during layout.

Buffers, Drivers, Receivers, Transceivers Part Context

This component belongs to the 74ACT logic family, which bridges the performance gap between older TTL standards and modern CMOS technologies. It shares functional similarities with other octal buffers like the 74AC244 but offers improved switching speeds and noise immunity. The device is part of onsemi's extensive portfolio of standard logic ICs used in general-purpose digital electronics.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-to-pin replacements include MC74AC244MX and MC74ACT244MX. Verify that substitute parts maintain the same 3-state output functionality and voltage operating ranges. Check for any differences in propagation delay or output drive strength if signal integrity is critical to the application design.
