74AHC1G4212GWH

Counter Dividers Overview

The Nexperia 74AHC1G4212GWH is a 12-stage divider and oscillator housed in a TSSOP5 (SOT353-1) package. It contains a chain of 12 flip-flops that count up to 4096, dividing the input frequency by this factor. The device operates with a supply voltage range of 2.0 V to 5.5 V and supports an input frequency range from 70 MHz to 165 MHz. Static characteristics include a maximum supply current of 40 μA at 5.5 V and low leakage currents. Dynamic performance specifies propagation delays between 22 ns and 51 ns depending on load capacitance and temperature.

Counter Dividers Feature Summary

• Integrates a 12-stage binary counter chain for frequency division by 4096
• Includes an inverting stage functioning as a crystal oscillator or external buffer
• Features overvoltage tolerant inputs compatible with mixed voltage environments
• Provides high noise immunity and robust latch-up protection

Counter Dividers Applications

• Crystal oscillator circuits utilizing external components
• Frequency division in digital signal processing systems
• Voltage level translation between different logic domains

Counter Dividers Procurement Notes

Verify the specific suffix GWH corresponds to the TSSOP5 plastic thin shrink small outline package with a body width of 1.25 mm. Confirm the temperature range specification matches the -40 °C to +125 °C requirement for your application environment. Ensure ordering documentation references the correct marking code C2 for identification purposes during assembly inspection.

Counter Dividers Selection Notes

Select this component when a single-chip solution for high-ratio frequency division is required within a minimal footprint. The device is suitable for designs needing operation across a wide voltage range without additional level shifting circuitry. Consider the package thermal derating characteristics if operating near the upper temperature limits with significant power dissipation loads.

Counter Dividers Part Context

This part belongs to the 74AHC series of high-speed CMOS logic devices manufactured by Nexperia. It is designed for applications requiring low power consumption and high noise immunity. The device complements other logic families by providing specialized counting functions in a compact surface-mount package suitable for dense PCB layouts.

Counter Dividers Replacement Considerations

Consult official Nexperia documentation for verified substitute part numbers. Cross-referencing requires matching the 12-stage divider functionality, TSSOP5 package dimensions, and electrical specifications.
