74ACT244PC

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ACT244PC is an octal buffer and line driver featuring three-state outputs, designed for memory address driving, clock distribution, and bus-oriented transmission. It operates within a supply voltage range of 4.5 V to 5.5 V and supports propagation delays as low as 10 ns. The device provides high drive capability with output source/sink currents of 24 mA and includes TTL-compatible inputs. Packaged in a 20-pin DIP format, it functions reliably across an industrial temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal buffer and line driver architecture providing eight independent non-inverting channels
• Three-state outputs enable direct connection to bus lines without external pull-up resistors
• TTL-compatible input thresholds simplify interfacing with legacy logic families
• High current drive capability allows direct loading of standard logic loads

• Memory address drivers for high-density PC boards
• Clock signal distribution networks
• Bus-oriented transmitter and receiver circuits

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the package type matches the specific suffix; 'PC' typically denotes a 20-pin DIP. Confirm RoHS compliance status through official datasheets or ordering information. Ensure the operating voltage aligns with the 4.5 V to 5.5 V specification. Check for moisture sensitivity levels if surface mount handling is required, though this is a through-hole part. Validate lead-free certification requirements against project specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with three-state control is required for bus applications. The ACT series offers faster switching speeds compared to standard AC logic while maintaining CMOS power efficiency. Ensure the design accommodates the 24 mA output drive capability. Verify that the 20-pin DIP package fits the available PCB footprint and assembly constraints.

Buffers, Drivers, Receivers, Transceivers Part Context

This component belongs to the 74ACT family of high-speed CMOS logic devices manufactured by onsemi. It is functionally compatible with other octal buffers like the MC74AC244 but features TTL-compatible inputs. The device is part of a broader portfolio of bus transceivers and drivers designed for improving circuit density and performance in digital systems.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include MC74AC244PC and MC74ACT244PC from onsemi. Cross-manufacturer equivalents such as SN74ACT244N from Texas Instruments may be considered if pin compatibility is verified. Always confirm electrical parameters and package dimensions before substitution.
