Product details

Overview

74AHC1G09QW5-7 from Diodes Incorporated is an automotive-grade, single 2-input positive AND gate with open-drain output, operating from 2.0V to 5.5V supply, delivering 8mA sink current at V_CC = 4.5V, featuring Schmitt-trigger inputs and AEC-Q100 Grade 1 qualification (–40°C to +125°C), used in level-shifting and wired-AND bus interfaces.

For engineers reviewing the 74AHC1G09QW5-7 datasheet, 74AHC1G09QW5-7 pinout, 74AHC1G09QW5-7 application, or 74AHC1G09QW5-7 equivalent, key selection criteria include open-drain logic compatibility, input voltage tolerance beyond V_CC, propagation delay under 7.9ns (CL = 15pF, V_CC = 3.3V), and thermal resistance (θ_JA = 184°C/W) for SOT25-packaged automotive signal conditioning.

Technical Context

This device implements a Boolean AND function (Y = A • B) using CMOS technology with open-drain output requiring external pull-up; all inputs incorporate Schmitt-trigger action to tolerate slow-rising/falling edges up to 100 ns/V at 3.3V.

It supports mixed-voltage interfacing due to input voltage range (–0.5V to 6.5V) independent of V_CC, and achieves balanced propagation delays (t_PD = 3.5ns typ. at 5V/15pF) and drive capability across temperature (–40°C to +125°C).

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Function	2-input positive AND with open-drain output - enables wired-AND bus topology and level translation.
Supply Voltage Range	2.0V to 5.5V - interoperable across 2.5V, 3.3V, and 5V systems without level shifters.
Output Sink Current	8mA at V_CC = 4.5V - sufficient to drive standard TTL loads or LED indicators directly.
Propagation Delay	3.5ns typical (V_CC = 5V, CL = 15pF) - supports >100MHz toggle rates in low-load configurations.
Input Hysteresis	Schmitt-trigger inputs with ~0.3V threshold hysteresis - rejects noise on slow control lines (e.g., sensors, switches).
Operating Temperature	–40°C to +125°C ambient (Grade 1) - qualified per AEC-Q100 for engine bay and powertrain ECUs.
ESD Robustness	2kV HBM, 1kV CDM - exceeds automotive ESD immunity requirements for in-vehicle harness coupling.

Pinout & Package

SOT25 (3.0mm × 2.8mm × 1.2mm, 0.95mm lead pitch) - surface-mount package with exposed pad not present; moisture sensitivity level 1 per J-STD-020.

Pin/Terminal	Circuit Role	Design Meaning
1 (A)	Data Input	First AND operand; accepts voltages up to 6.5V regardless of V_CC - enables high-side sensing.
2 (B)	Data Input	Second AND operand; Schmitt-triggered - suppresses bounce on mechanical switch inputs.
3 (GND)	Ground Reference	Return path for output sink current and internal logic; must be low-impedance for stable noise margin.
4 (Y)	Open-Drain Output	Active-low capable output; requires external pull-up to define high state - supports I²C-compatible bus sharing.
5 (V_CC)	Power Supply	CMOS rail for internal logic; decoupling capacitor (100nF) recommended within 5mm of pin.

Key Features

Feature	Design Value
Automotive Qualification	AEC-Q100 Grade 1 qualified, PPAP-capable, manufactured in IATF 16949 facilities - meets OEM sourcing mandates.
Voltage-Tolerant Inputs	Inputs rated –0.5V to 6.5V independent of V_CC - eliminates need for external clamping diodes in mixed-supply domains.
Low Dynamic Power	ICC = 1µA typical at V_CC = 5.5V, TA = 25°C - reduces quiescent load in always-on vehicle modules.
Thermal Performance	θ_JA = 184°C/W (SOT25) - enables operation at full rating in compact PCB layouts without heatsinking.
Green Compliance	Totally lead-free, halogen- and antimony-free (<900ppm Br/Cl, <1000ppm Sb) - satisfies EU ELV and RoHS 3 requirements.

Equivalent & Alternatives

The following parts are listed as comparable options for similar open-drain AND gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC1G09DBVR	Lower V_CC min (1.65V), no Schmitt inputs, 32mA sink, non-automotive grade	Lacks AEC-Q100 qualification and input hysteresis - unsuitable for noisy automotive harness environments	Select only for cost-sensitive industrial controls where ambient ≤85°C and ESD <1kV expected
74AUP1G09GW,125	Wider V_CC range (0.8V–3.6V), 4mA sink, AEC-Q100 Grade 2 (–40°C to +105°C), smaller XSON package	Insufficient high-temp rating for under-hood use; lower sink current limits LED drive capability	Prefer for space-constrained infotainment subsystems where 105°C max ambient suffices

Compared with SN74LVC1G09DBVR and 74AUP1G09GW,125, the 74AHC1G09QW5-7 uniquely combines Grade 1 temperature support, Schmitt-trigger noise immunity, and 8mA sink in SOT25 - making it the only drop-in solution for engine-control logic arbitration requiring robustness at 125°C.

FAQ

Is an external pull-up resistor required for 74AHC1G09QW5-7 operation?

Yes - the open-drain output cannot source current; a pull-up resistor (typically 1kΩ–10kΩ) to a defined voltage rail is mandatory to establish a valid logic HIGH state. The value must balance rise time (CL × R) against sink current capability (≤8mA) and power consumption.

Can inputs exceed V_CC without damage?

Yes - inputs are rated from –0.5V to +6.5V regardless of V_CC level, enabling direct connection to higher-voltage sensors or buses without clamping diodes. This is confirmed in Absolute Maximum Ratings (VI range) and Recommended Operating Conditions.

What is the maximum capacitive load this device can drive reliably?

The datasheet specifies switching characteristics up to 50pF (t_PD = 14.5ns max at –40°C to +125°C, V_CC = 3.3V). Driving >50pF risks exceeding propagation delay specs and may cause signal integrity issues; for heavier loads, add a buffer stage or reduce trace length.

Does 74AHC1G09QW5-7 support hot-swap or live-insertion?

No - the device lacks powered-off protection circuitry. Applying input signals while V_CC is unpowered violates Absolute Maximum Ratings (VI must stay within –0.5V to V_CC + 0.5V), risking latch-up or ESD damage. Always sequence V_CC before asserting inputs.
