Overview
The MC74HC244AFL2 is an octal buffer and line driver manufactured by onsemi. It belongs to the HC logic series and features non-inverting polarity with three-state outputs. The device operates within a supply voltage range of 2 V to 6 V. It utilizes a SOIC-J-20 surface-mount package. Key electrical parameters include a maximum low-level output current of 7.8 mA and a high-level output current of -7.8 mA. Static current is specified at 4 uA. Power dissipation is rated at 500 mW. Propagation delay varies from 96 ns at 2 V to 15 ns at 6 V. The component supports an operating temperature range from -55 C to +125 C.
Feature Summary
- Provides eight non-inverting buffer channels for signal transmission.
- Features three-state outputs to facilitate bus-oriented architectures.
- Operates across a wide industrial temperature range.
Applications
- Bus-oriented systems requiring signal buffering
- Memory address drivers
- Clock drivers
Procurement Notes
Verify the specific suffix 'L2' against official datasheets, as standard variants typically use 'G' or 'DTR2G'. Confirm availability status, as related HC244 models may be discontinued. Ensure RoHS compliance documentation matches the exact part number before procurement.
Selection Notes
Select this component for applications requiring octal buffering with three-state control. Verify that the 2 V to 6 V supply range meets system requirements. Check package compatibility for the SOIC-J-20 footprint. Ensure input levels are compatible with the HC logic family standards.
Part Context
This part is an octal buffer within the HC logic family. It serves as a bus driver for digital systems. The device provides isolation and signal strengthening. It is designed for high-speed applications requiring multiple parallel data lines.
Replacement Considerations
Check for MM74HC244 or MC74HC244 variants. Verify pinout and electrical specifications match exactly. Suffix differences may indicate packaging or compliance variations rather than functional changes.
