74AHC1G4210GWH

Counter Dividers Overview

The Nexperia 74AHC1G4210GWH is a single 10-stage divider and oscillator housed in a 5-TSSOP (SOT353-1) package. It consists of a chain of 10 flip-flops that divide the input frequency by 1024, advancing on negative-going transitions. The device includes an inverting stage (X1 to X2) for crystal oscillation or external buffering. Operating voltage ranges from 2.0 V to 5.5 V with overvoltage tolerant inputs up to 5.5 V. Maximum operating temperature is +125 °C.

Counter Dividers Feature Summary

• Integrates a 10-stage binary counter chain for frequency division by 1024.
• Includes an internal inverting stage suitable for crystal oscillator or buffer applications.
• Features overvoltage tolerant inputs allowing operation in mixed voltage environments.

Counter Dividers Applications

• Frequency division circuits requiring a divide-by-1024 ratio.
• Crystal oscillator designs utilizing the internal inverting stage.
• Voltage level translation between mixed voltage logic domains.

Counter Dividers Procurement Notes

Verify the specific suffix 'GWH' against the manufacturer's current ordering information to confirm the exact package variant and marking code. Ensure the application environment remains within the specified -40 °C to +125 °C temperature range and supply voltage limits. Confirm RoHS compliance requirements align with the product data sheet specifications before finalizing procurement.

Counter Dividers Selection Notes

Select this component when a compact, single-chip solution for dividing high-frequency signals by 1024 is required. The 5-TSSOP package offers space efficiency for surface-mount designs. Consider the overvoltage tolerance if interfacing with higher voltage logic levels directly without additional protection components.

Counter Dividers Part Context

This part belongs to the 74AHC series of CMOS logic devices manufactured by Nexperia. It is functionally related to other dividers in the 74AHC1G42xx family, such as the 74AHC1G4215 which provides a 15-stage division. The GWH suffix indicates the specific plastic thin shrink small outline package configuration.

Counter Dividers Replacement Considerations

Direct substitutes include other 10-stage dividers from the same family, such as the 74AHC1G4210GM. Verify pin compatibility and electrical characteristics against the target design requirements before substitution.

Counter Dividers FAQ

How does the device handle the input signal transition?

The divider advances on the negative-going transition of the X1 clock input.

What is the function of the X2 pin?

The X2 pin serves as the oscillator output for the internal inverting stage. When used as a buffer for an external oscillator, this output should be left floating.
