MM74C14N

Inverter Gates Overview

The MM74C14N is a monolithic CMOS Hex Schmitt Trigger featuring six independent inverters with built-in hysteresis. It operates within a supply voltage range of 3.0V to 15V and supports an operating temperature range from -55°C to +125°C. The device utilizes N- and P-channel enhancement transistors, ensuring low power consumption and high noise immunity. Key electrical characteristics include a typical propagation delay of 400ns at 5V and guaranteed hysteresis of at least 0.2 VCC. Inputs are protected against static discharge via internal diode clamps.

Inverter Gates Procurement Notes

Verify the package type matches the specific suffix; 'N' denotes the 14-lead Plastic Dual-In-Line Package (PDIP). Confirm that the ordering code corresponds to the required manufacturing source, as Fairchild Semiconductor was acquired by onsemi. Ensure compliance with RoHS directives if applicable to the production environment. Check for availability in tape and reel options by appending the 'X' suffix if automated assembly is required.

Inverter Gates Selection Notes

Select this component when a wide supply voltage range and robust noise immunity are required for signal inversion. The MM74C14N is suitable for applications involving TTL compatibility or interfacing with LPTTL standards. Consider the PDIP package for through-hole prototyping or environments where surface-mount technology is not feasible. Evaluate the propagation delay specifications against the system timing requirements before finalizing the design.

Inverter Gates Part Context

The MM74C14N belongs to the 74C series of CMOS logic integrated circuits. Originally manufactured by Fairchild Semiconductor, this product line is now part of onsemi's portfolio following corporate acquisition. The 74C family is characterized by its wide operating voltage range compared to standard 74LS TTL logic, making it versatile for various analog and digital interface applications requiring Schmitt trigger functionality.

Inverter Gates Replacement Considerations

Equivalent parts include the MM74HC14 for high-speed CMOS applications and the MM74HCT14 for direct TTL compatibility. Verify pinout compatibility and electrical characteristics such as propagation delay and output drive current when substituting.
