74AHC1G4214GW-Q10H

Counter Dividers Overview

The Nexperia 74AHC1G4214GW-Q10H is a single-channel, 14-stage frequency divider and oscillator integrated circuit. It comprises a chain of 14 flip-flops that divide the input frequency by 16384 (2^14). The device operates on negative-going transitions at the X1 clock input. Pin X2 serves as an oscillator output or can be left floating when used as a buffer. The component supports a supply voltage range from 2.0 V to 5.5 V and functions within ambient temperatures of -40 °C to +125 °C. It utilizes a TSSOP5 plastic thin shrink small outline package.

Counter Dividers Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standards for reliability in vehicle applications.
• Overvoltage tolerant inputs allow operation in mixed voltage environments without level shifting requirements.
• Integrated crystal oscillator capability enables standalone timing generation using external components.
• High noise immunity and low power dissipation characteristics suitable for dense circuit designs.

Counter Dividers Applications

• Frequency division circuits requiring high division ratios
• Crystal oscillator implementations for clock generation
• Voltage level translation in mixed-signal automotive systems

Counter Dividers Procurement Notes

Verify the specific suffix 'Q10H' against official Nexperia documentation to confirm exact marking codes and package variations. Ensure compatibility with AEC-Q100 Grade 1 requirements if deploying in automotive contexts. Cross-reference the ordering information table for precise temperature ranges and package dimensions before finalizing procurement specifications.

Counter Dividers Selection Notes

Select this component when a single-chip solution for dividing frequencies by 16384 is required. It is appropriate for designs needing overvoltage tolerance up to 5.5 V on inputs while operating at lower supply voltages. Consider its automotive qualification status if the application demands compliance with strict industry reliability standards.

Counter Dividers Part Context

This part belongs to the 74AHC1G4214-Q100 family of 14-stage dividers. It shares functional similarities with other single-gate logic devices but is distinct due to its internal counter chain architecture. The product line emphasizes compact packaging and robust performance across wide temperature ranges for industrial and automotive sectors.

Counter Dividers Replacement Considerations

Direct substitutes include other 14-stage dividers from the same manufacturer series. Verify pinout compatibility and electrical parameters such as propagation delay and supply voltage limits before swapping components in existing designs.

Counter Dividers FAQ

How does the device function as an oscillator?

The X1 and X2 pins form an inverting stage that can drive an external crystal. A bias resistor and limiting resistor are typically connected between these pins to establish oscillation conditions.

What happens to the X2 pin when used as a buffer?

When the device is used strictly as a frequency divider buffer rather than an oscillator, the X2 pin should be left floating to prevent interference with the counting chain.
