MC74ACT244ML1

Overview

The MC74ACT244ML1 is an octal buffer and line driver from the onsemi ACT logic family, housed in a 20-lead TSSOP package. It features three-state outputs capable of sourcing and sinking 24 mA. The device operates within a supply voltage range of 2 V to 6 V and exhibits a maximum propagation delay of 10 ns at typical loads. It supports bidirectional data transfer and functions as a non-inverting buffer for bus-oriented applications.

Feature Summary

• Octal configuration providing eight independent non-inverting buffers or line drivers
• Three-state output capability allowing direct connection to bus lines without additional pull-up resistors
• High drive strength with 24 mA source and sink current capabilities for improved signal integrity
• TTL-compatible inputs ensuring compatibility with standard logic families

Applications

• Memory address drivers for high-density PC boards
• Clock distribution circuits requiring fast switching speeds
• Bus-oriented transmitter and receiver interfaces

Procurement Notes

Verify the specific suffix 'ML1' against official onsemi documentation to confirm pinout and electrical characteristics match the standard MC74ACT244 series. Ensure the component is sourced from authorized distributors to guarantee authenticity and compliance with RoHS standards. Cross-reference the datasheet revision date to ensure alignment with current manufacturing specifications.

Selection Notes

Select this component when designing systems requiring high-speed buffering with significant drive current. The ACT series offers faster performance than standard AC logic while maintaining CMOS power efficiency. Consider the TSSOP package size for space-constrained layouts. Verify that the 2 V to 6 V operating range aligns with the system's power supply rails and that input levels remain TTL-compatible.

Part Context

This part belongs to the 74ACT244 family of octal buffers. It shares functional similarities with the MC74AC244 but includes TTL-compatible inputs. The device is designed to replace older bipolar logic families in modern digital systems, offering improved density and speed. It is commonly used in conjunction with other ACT series components for complex digital interfacing tasks.

Replacement Considerations

Direct substitutes include MC74ACT244DTR2G and MC74ACT244SCX. Verify package compatibility (TSSOP vs SOIC) and suffix variations before substitution.
