Nexperia USA Inc. 74AHC1G4210GW-Q10H

Overview

74AHC1G4210GW-Q10H from Nexperia is an automotive-qualified 10-stage binary counter and crystal oscillator IC. It implements a chain of ten cascaded D-type flip-flops to divide input frequency by 1024, features overvoltage-tolerant X1 input (up to 5.5 V), operates from 2.0 V to 5.5 V supply, and delivers Q output with propagation delay as low as 17 ns at 5 V. It is used in automotive clock tree reduction and low-frequency timing generation.

For engineers reviewing the 74AHC1G4210GW-Q10H datasheet, 74AHC1G4210GW-Q10H pinout, 74AHC1G4210GW-Q10H application, or 74AHC1G4210GW-Q10H equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification, 1024:1 fixed division ratio, TSSOP5 package compatibility, and dual-mode operation as either crystal oscillator or external clock buffer.

Technical Context

The device integrates a single inverting stage (X1→X2) configured as either a Pierce crystal oscillator driver or a level-translating input buffer - when used as a buffer, X2 must be left floating. The 10-stage synchronous counter advances on the negative-going edge of X1, producing a precise /1024 divided output at Q.

Its overvoltage-tolerant X1 input enables mixed-voltage system interfacing without external level shifters, while CMOS architecture ensures low static current (≤40 μA at 5.5 V) and high noise immunity across -40 °C to +125 °C ambient range.

FAQ

What is the function of the X2 pin when using an external clock source?

When X1 is driven by an external clock (not a crystal), the X2 pin must be left electrically floating. It is the internal inverter output and is not intended to drive any load in buffer mode; connecting it may cause oscillation instability or excessive current draw.

Can the 74AHC1G4210GW-Q10H operate with a 1.8 V supply?

No. The device has a minimum recommended supply voltage of 2.0 V per Table 5. Operation below 2.0 V violates recommended conditions and may result in undefined logic states, increased propagation delay variability, or failure to meet AEC-Q100 timing specifications.

How does the overvoltage tolerance on X1 improve system design?

The X1 input accepts voltages up to 5.5 V independently of VCC, allowing direct connection of 5 V clock sources (e.g., legacy microcontrollers or crystals) into 3.3 V-powered systems without external level shifters - reducing BOM count, PCB area, and signal integrity risk.

Is the Q output edge-aligned or phase-shifted relative to X1?

The Q output transitions occur on the negative-going edge of X1, with a fixed propagation delay (17–44 ns depending on VCC and load). There is no programmable phase offset - the output is strictly synchronous to the X1 falling edge, making it suitable for deterministic timing chains.
