74AHC1G4214GWH

Counter Dividers Overview

The Nexperia 74AHC1G4214GWH is a single-channel 14-stage frequency divider and oscillator housed in a TSSOP5 (SOT353-1) package. It consists of a chain of 14 flip-flops that divide the input frequency by 16384, advancing on negative-going transitions. The device operates within a supply voltage range of 2.0 V to 5.5 V and supports an input frequency up to 165 MHz at 5 V. It features overvoltage tolerant inputs, high noise immunity, and low power dissipation.

Counter Dividers Feature Summary

• Integrates a 14-stage binary counter chain for frequency division by 16384
• Includes an internal inverting stage suitable for crystal oscillator or external buffer applications
• Provides overvoltage tolerant inputs allowing operation in mixed-voltage environments

Counter Dividers Applications

• Crystal oscillator circuits with external biasing components
• Frequency division in digital signal processing systems
• Clock generation and distribution networks

Counter Dividers Procurement Notes

Verify the specific ordering suffix 'GW' corresponds to the TSSOP5 plastic thin shrink small outline package with a body width of 1.25 mm. Confirm the temperature range requirement matches the -40 °C to +125 °C specification. Ensure the application environment does not exceed the absolute maximum ratings for supply voltage or input clamping current to prevent permanent damage.

Counter Dividers Selection Notes

Select this component when a single-chip solution for high-ratio frequency division is required. The device is suitable for designs needing a wide supply voltage range from 2.0 V to 5.5 V. Consider the overvoltage tolerant inputs if interfacing with logic levels exceeding the supply voltage. Verify that the output load capacitance requirements are met within the specified propagation delay limits.

Counter Dividers Part Context

This part belongs to the 74AHC series of high-speed CMOS logic devices manufactured by Nexperia. The AHC family offers performance comparable to the 74AC series while maintaining compatibility with standard 5 V CMOS logic levels. The '1G' designation indicates a single circuit configuration in a minimal footprint package, optimizing board space for compact electronic designs.

Counter Dividers Replacement Considerations

Check for other variants within the 74AHC1G42xx series, such as the 74AHC1G4210, which provides a different division ratio. Ensure any substitute maintains the same TSSOP5 package dimensions and pinout configuration to fit existing footprints without redesign.
