Overview
The MC74HCT244AFG is an octal 3-state non-inverting buffer and line driver manufactured by onsemi. It operates within a supply voltage range of 4.5 V to 5.5 V. The device features eight inputs and eight outputs, housed in a SOEIAJ-20 package. Key electrical parameters include a high-level output current of -6 mA and a low-level output current of 6 mA. Static current is specified at 4 uA, with a maximum operating temperature of +85 C.
Feature Summary
- Provides octal buffering and line driving capabilities with three-state output control.
- Features non-inverting logic functionality for signal transmission.
- Compatible with TTL or NMOS interfaces, serving as a level converter.
Applications
- Interfacing TTL or NMOS logic families
- Level conversion applications
- Octal bus buffer implementations
Procurement Notes
Verify the specific suffix FG against official datasheets to confirm package type and tape/reel specifications. Ensure compatibility with required operating temperatures and voltage ranges. Cross-reference pinout assignments with legacy LS244 designs if used as a drop-in replacement. Confirm RoHS compliance status through manufacturer documentation prior to integration.
Selection Notes
Select this component when an octal buffer with three-state outputs is required for 5V logic systems. It serves as a functional equivalent to LS244 devices but utilizes HCT CMOS technology. Consider the SOEIAJ-20 package constraints for PCB layout. Verify input/output current requirements match the load characteristics of the destination circuitry.
Part Context
This part belongs to the MC74HCT244A series of buffers and line drivers from onsemi. The series is designed for high-speed digital applications requiring multiple buffered channels. It falls under the broader category of logic ICs, specifically within the buffer and line driver subcategory for CMOS logic families.
Replacement Considerations
The datasheet states the MC74HCT244A is identical in pinout to the LS244. This allows for potential direct pin-compatible substitution in existing designs utilizing the LS244, provided voltage and speed requirements are met.
