Overview
The MC74AC244ML1 is an octal buffer and line driver manufactured by onsemi, belonging to the AC logic series. It features eight non-inverting inputs and three-state outputs housed in a 20-lead SOIC package. The device operates within a supply voltage range of 2 V to 6 V. Key electrical parameters include a high-level output current of -24 mA and a low-level output current of 24 mA. Static current is specified at 8 uA, with a maximum operating temperature of +85 C and a minimum of -40 C. Propagation delay is 9 ns at 3.3 V and 7 ns at 5 V.
Feature Summary
- Provides octal buffering and line driving capabilities for memory address registers and bus-oriented transmitters.
- Features three-state outputs that allow direct connection to bus lines without additional drivers.
- Offers improved PC board density through its compact surface-mount packaging.
Applications
- Memory address drivers
- Clock drivers
- Bus-oriented transmitter/receiver applications
Procurement Notes
Verify the specific suffix ML1 against the official onsemi datasheet to confirm pinout compatibility and package dimensions. Ensure the component meets RoHS requirements if mandated by your design specifications. Cross-reference the ordering information with authorized distributors to confirm availability and authenticity before procurement.
Selection Notes
Select this component when designing systems requiring octal buffering with three-state control. It is suitable for applications needing drive currents up to 24 mA. Consider the 2 V to 6 V operating range and propagation delays when evaluating timing constraints. Verify that the SOIC-20 package fits the PCB layout requirements.
Part Context
This part belongs to the MC74AC244 family of octal buffers. It shares functional similarities with other AC series devices but is distinguished by its specific package and suffix. It serves as a standard solution for digital signal buffering in CMOS logic circuits, providing isolation and drive strength for complex digital systems.
Replacement Considerations
Check for compatible substitutes such as MC74AC244DWG or MC74ACT244 variants. Ensure logical equivalence and pin compatibility before substitution. Verify that alternative parts meet the same voltage and current specifications.
