Product details

Overview

74AHC1G4215GW-Q10H from Nexperia is an automotive-qualified 15-stage binary divider and oscillator IC with overvoltage-tolerant X1 input (up to 5.5 V), 32768:1 frequency division ratio, TSSOP5 (SOT353-1) package, and operation from -40 °C to +125 °C. It functions as a crystal oscillator or external clock buffer, delivering Q output at f_IN/32768 on negative-going X1 edges - used in engine control unit timing reference and infotainment system clock tree synchronization.

For engineers reviewing the 74AHC1G4215GW-Q10H datasheet, 74AHC1G4215GW-Q10H pinout, 74AHC1G4215GW-Q10H application, or 74AHC1G4215GW-Q10H equivalent, this page delivers verified functional role, exact pin-level circuit behavior, automotive-grade operating margins, and validated alternative options for AEC-Q100-compliant timing design.

Technical Context

This device implements a synchronous 15-bit ripple counter using cascaded D flip-flops, advancing only on the falling edge of X1. Its single inverting stage (X1→X2) supports crystal oscillation (with external R_bias, C₁, C₂) or acts as a level-translating buffer - X2 must be left floating when used as buffer.

The X1 input's overvoltage tolerance (to 5.5 V) enables direct interfacing with 5 V logic in mixed-voltage automotive domains without external level shifters. Output Q exhibits propagation delays of 24–88 ns (depending on V_CC and load), with maximum input frequency up to 125 MHz at V_CC = 3.3 V and 100 MHz at V_CC = 5 V under full temperature range.

Key Specifications

Parameter	Value and Actual Design Meaning
Division Ratio	32768:1 - provides precise low-frequency timing (e.g., 32.768 kHz output from 1 GHz input) for real-time clock derivation.
Supply Voltage Range	2.0 V to 5.5 V - supports direct integration into 3.3 V and 5 V automotive subsystems without regulation.
Operating Temperature	-40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and powertrain applications.
X1 Input Tolerance	Up to 5.5 V - allows safe connection to higher-voltage signal sources without clamping diodes or resistors.
Q Output Drive	±8 mA at V_CC = 4.5 V - sufficient to drive standard CMOS loads or small capacitive traces without buffering.
Propagation Delay (X1→Q)	24–88 ns - defines worst-case timing margin for downstream logic sampling of divided clock.
Power Dissipation	Max 250 mW at T_amb ≤ 74 °C, derated 3.3 mW/K above - enables thermal-aware placement in dense ECUs.

Pinout & Package

TSSOP5 (SOT353-1) plastic thin shrink small outline package: 5-lead, 1.25 mm body width, 0.65 mm pitch, pin 1 indicator at lower-left corner below marking "C6".

Pin/Terminal	Circuit Role	Design Meaning
X1	Clock input / oscillator driver	Negative-edge-triggered input; overvoltage tolerant to 5.5 V; connects to crystal or external clock source.
X2	Oscillator feedback / buffer output	Inverting output of first stage; must be left floating when used as input buffer; connects to crystal in oscillator mode.
GND	Ground reference (0 V)	Primary return path for supply current and signal references; requires low-impedance PCB connection.
Q	15-stage divider output	Final counter output; frequency = f_X1/32768; CMOS-compatible swing from GND to V_CC.
V_CC	Positive supply voltage	Accepts 2.0–5.5 V; powers all 15 flip-flops and output stage; decoupling capacitor required near pin.

Key Features

Feature	Design Value
AEC-Q100 Grade 1 qualification	Validated for automotive use across -40 °C to +125 °C ambient, including lifetime reliability testing per stress conditions.
Overvoltage-tolerant X1 input	Operates safely with 5.5 V signals while powered from 2.0–5.5 V - eliminates need for external level-shifting components.
Crystal oscillator integration	Internal inverter enables self-contained 32.768 kHz crystal oscillator with only two external capacitors and bias resistor.
Low dynamic power dissipation	CPD = 4–5 pF - minimizes switching current in high-frequency clock trees, reducing system-level power budget impact.
High noise immunity	Guaranteed VIH/VIL margins (e.g., VIH ≥ 4.4 V at V_CC = 5.5 V) ensure robust operation in electrically noisy vehicle environments.

Applications

Infotainment System Clock Tree

Use Scenario: Generating stable 32.768 kHz timebase from a 1.069 MHz crystal for ECU real-time clock and watchdog timer.

IC Role / Device Role / Timing Role: Primary oscillator + frequency divider - replaces discrete crystal oscillator + separate counter IC.

Use Value: Reduces BOM count by two components and improves long-term frequency stability via integrated oscillator architecture.

Use Scenario: Deriving synchronized audio sample-rate clocks (e.g., 44.1 kHz/48 kHz) from a master 12.288 MHz oscillator in head unit SoC interface.

IC Role / Device Role / Timing Role: Clock domain translator and divider - converts high-speed SoC clock to lower-rate peripheral timing.

Use Value: Enables deterministic phase alignment between audio DAC and display controller using single shared source.

Body Control Module (BCM) Wake-Up Timer

ADAS Camera Sensor Sync

Use Scenario: Providing periodic wake-up pulses (e.g., every 2 seconds) to low-power microcontroller in door module during sleep mode.

IC Role / Device Role / Timing Role: Autonomous low-power timing generator - operates independently of MCU clock domain.

Use Value: Extends battery life by eliminating MCU polling; achieves <1 μA quiescent current via internal CMOS design.

Use Scenario: Synchronizing rolling shutter exposure timing across multiple camera sensors in surround-view system.

Use Value: Eliminates frame skew between cameras by ensuring sub-100 ns inter-sensor timing deviation.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 15-stage divider and oscillator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
74LVC1G4215GW-Q10H	Lower V_CC range (1.65–5.5 V); reduced max f_IN (80 MHz @ 125 °C); same pinout and function.	Better suited for 1.8 V logic domains; not recommended for >100 MHz input in extended temperature.	Select when supply rail is 1.8 V or system clock <80 MHz; verify timing margin at worst-case temp.
CD4060BM96-Q1	14-stage counter (16384:1); wider V_CC (3–18 V); bipolar CMOS process; larger SOIC-16 package.	Supports higher-voltage sensor interfaces but lacks overvoltage-tolerant inputs and automotive qualification.	Choose only for legacy 14-stage designs or non-automotive 12 V systems; not AEC-Q100 qualified.

Compared with 74LVC1G4215GW-Q10H, the 74AHC1G4215GW-Q10H delivers 25% higher max input frequency and guaranteed overvoltage tolerance; versus CD4060BM96-Q1, it offers smaller footprint, automotive qualification, and precise 32768:1 ratio essential for RTC accuracy.

FAQ

Can 74AHC1G4215GW-Q10H operate with a 1.8 V supply?

No - the minimum specified V_CC is 2.0 V per Table 5. At 1.8 V, VIH thresholds (e.g., 1.7 V at V_CC = 2.0 V) would not be met, risking unreliable logic recognition. Use 74LVC1G4215GW-Q10H for 1.8 V systems.

What happens if X2 is not left floating when used as an input buffer?

Leaving X2 connected while using it as a buffer creates unintended feedback that disrupts the inverter's DC operating point, causing oscillation instability or failure to propagate X1 transitions to Q. The datasheet explicitly requires X2 to be unconnected in buffer mode.

Is the 32768:1 division ratio programmable or fixed?

Fixed - the 15-stage ripple counter is hardwired; no configuration pins, registers, or external controls exist. The division ratio is inherent to the chain of 15 D flip-flops and cannot be altered without external logic.

Does this device support crystal frequencies other than 32.768 kHz?

Yes - while optimized for 32.768 kHz crystals (via typical R_bias = 2.2 kΩ and C₁/C₂ values), it supports fundamental-mode crystals from 100 kHz to 2 MHz. Maximum reliable oscillation frequency is limited by t_pd(X1→X2) and crystal motional parameters.
