74AHC1G4208GW-Q10H

Counter Dividers Overview

The Nexperia 74AHC1G4208GW-Q10H is an automotive-qualified 8-stage divider and oscillator housed in a TSSOP5 (SOT353-1) package. It comprises a chain of eight flip-flops that divide the input frequency by 256, advancing on negative-going transitions. The device operates within a supply voltage range of 2.0 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. It features overvoltage tolerant inputs up to 5.5 V, enabling use as a voltage level translator in mixed-voltage environments.

Counter Dividers Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards for extended temperature reliability.
• Integrated crystal oscillator functionality via an inverting stage between X1 and X2 pins.
• Overvoltage tolerant inputs allow direct interfacing with higher voltage signals without damage.
• High noise immunity and low power dissipation characteristics suitable for demanding electronic applications.

Counter Dividers Applications

Counter Dividers FAQ

How does the device function as an oscillator?

The single inverting stage between pins X1 and X2 can be configured with external components like a crystal and resistors to form a self-sustaining oscillator circuit.

What happens to output X2 when used as a buffer?

When the device is utilized strictly as a frequency divider buffer, the datasheet specifies that the output X2 should be left floating.
