Overview
The onsemi 74AC374MTCX is an octal D-type flip-flop featuring three-state outputs, manufactured using silicon gate CMOS technology. It operates within a supply voltage range of 2 V to 6 V and supports surface-mount installation in a 20-TSSOP package. The device provides non-inverting outputs with propagation delays of 9 ns at 3.3 V and 7 ns at 5 V. Output drive capabilities include high-level currents of -24 mA and low-level currents of 24 mA. It functions reliably across an operating temperature range from -40 °C to +85 °C.
Feature Summary
- Octal D-type flip-flops with individual inputs and three-state true outputs
- Silicon gate CMOS technology for high-speed operation
- Non-inverting logic polarity with positive edge triggering
Applications
- Parallel data storage and buffering
- I/O port expansion in embedded systems
- Register file implementation in digital circuits
Procurement Notes
Verify the specific ordering suffix against official datasheets to confirm package type and tape/reel specifications. Ensure compatibility with RoHS directives and check for any recent PCN updates regarding manufacturing site or material changes before final procurement decisions.
Selection Notes
Select this component when eight parallel bits of storage with tri-state control are required. It is suitable for designs needing fast switching speeds within the AC series performance envelope. Consider the 20-TSSOP footprint for space-constrained PCB layouts requiring surface-mount assembly.
Part Context
This part belongs to the 74AC logic family, known for high-speed CMOS performance comparable to TTL but with lower power consumption. It serves as a fundamental building block for sequential logic circuits, providing reliable data retention and transfer capabilities in various digital applications.
Replacement Considerations
Compatible substitutes include MC74AC374DTR2G and MM74AC374MTCX. Verify pinout compatibility and electrical parameters such as output current and propagation delay when cross-referencing alternative manufacturers.
