MC74HCT244AFL1

Overview

The MC74HCT244AFL1 is an octal buffer and line driver manufactured by onsemi. It features eight non-inverting outputs with three-state control, allowing multiple drivers to share a bus. The device operates within a supply voltage range of 4.5 V to 5.5 V. It utilizes HCT CMOS technology, ensuring compatibility with standard TTL logic levels while offering low power consumption characteristics typical of CMOS devices.

Feature Summary

• Provides eight non-inverting buffer channels for signal driving applications
• Includes three-state output capability to facilitate bus-oriented systems
• Features HCT input compatibility for direct interfacing with TTL logic families

Applications

• Bus-oriented memory and address drivers
• Clock distribution circuits
• TTL-to-CMOS level translation interfaces

Procurement Notes

Verify the specific suffix 'FL1' against the manufacturer's current datasheet to confirm package dimensions and marking codes. Ensure the operating temperature range meets system requirements, as industrial variants may differ from commercial grades. Confirm RoHS compliance status if required for your manufacturing process.

Selection Notes

Select this component when an octal buffer with three-state control is required for 5V logic systems. It serves as a drop-in replacement for LS244 pinouts. Consider propagation delay specifications if high-speed switching is necessary. Verify that the load capacitance does not exceed the device's rated limits for reliable operation.

Part Context

This part belongs to the 74HCT logic family, designed for high-speed CMOS operations with TTL-compatible inputs. The '244' designation indicates an octal buffer configuration. The 'FL1' suffix typically denotes a specific tape-and-reel packaging format or regional variant within the SOIC-20 package family offered by onsemi.

Replacement Considerations

The MM74HCT244WM is a documented alternative from the same manufacturer. Other compatible parts include generic 74HCT244 equivalents from different vendors, provided they match the 20-pin SOIC footprint and electrical specifications.
