Product details

Overview

74AHCT3G04GD,125 from Nexperia is a triple CMOS inverter with TTL-compatible input thresholds, 4.5 V to 5.5 V supply range, ±8 mA output drive, and overvoltage-tolerant inputs up to 5.5 V. It operates across –40 °C to +125 °C and is packaged in XSON8 (SOT833-1), enabling level translation in mixed-voltage logic interfaces such as 5 V MCU I/O expansion.

For engineers reviewing the 74AHCT3G04GD,125 datasheet, 74AHCT3G04GD,125 pinout, 74AHCT3G04GD,125 application, or 74AHCT3G04GD,125 equivalent, key selection criteria include input threshold compatibility with legacy TTL systems, propagation delay under 8.5 ns at 5 V/50 pF, thermal derating behavior above 68 °C, and XSON8 footprint constraints for high-density PCB layouts.

Technical Context

This device implements three independent inverting buffers with identical TTL-level input switching (VIH = 2.0 V min, VIL = 0.8 V max) and rail-to-rail CMOS outputs. Each gate supports symmetrical output impedance and exhibits balanced tPLH/tPHL propagation delays.

Its overvoltage-tolerant inputs allow safe interfacing with 5.5 V signals even when VCC = 4.5 V, eliminating external clamping diodes in voltage-translating applications. The XSON8 package features 8 solderable terminals with 0.35 mm pitch and 1.0 × 1.95 × 0.5 mm body dimensions.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	4.5 V to 5.5 V - ensures compatibility with standard 5 V logic rails and tolerance to supply ripple.
Input Thresholds	VIH ≥ 2.0 V, VIL ≤ 0.8 V - matches TTL logic families for seamless integration with legacy microcontrollers and peripherals.
Output Drive	±8 mA at VCC = 4.5 V - sufficient to drive multiple 74-series inputs or small capacitive loads without buffering.
Propagation Delay	Max 8.5 ns at VCC = 5 V, CL = 50 pF - enables reliable operation in sub-100 MHz digital control paths.
Operating Temperature	–40 °C to +125 °C - qualified for industrial and extended-temperature embedded applications.
Input Overvoltage Tolerance	Up to 5.5 V regardless of VCC - permits direct connection to higher-voltage buses without external protection.
Power Dissipation Cap	250 mW at Tamb ≤ 68 °C, derates 3.1 mW/K above - defines thermal limits for continuous operation in compact enclosures.

Pinout & Package

XSON8 (SOT833-1) package: plastic extremely thin small outline, no leads, 8 terminals, body size 1.0 × 1.95 × 0.5 mm, 0.35 mm terminal pitch.

Pin/Terminal	Circuit Role	Design Meaning
1	Input A1	First inverter input; accepts 0–5.5 V signals independent of VCC.
2	Output Y3	Third inverter output; drives load referenced to GND/VCC rails.
3	Input A2	Second inverter input; electrically isolated from other inputs.
4	GND	Digital ground reference; must be low-impedance for noise immunity.
5	Output Y2	Second inverter output; shares same VCC/GND with all gates.
6	Input A3	Third inverter input; tolerant to 5.5 V even at VCC = 4.5 V.
7	Output Y1	First inverter output; provides inverted logic state with <8.5 ns delay.
8	VCC	Positive supply rail; decoupling capacitor required within 3 mm.

Key Features

Feature	Design Value
TTL-compatible input thresholds	Enables plug-in replacement of 74LS04 in legacy 5 V systems without redesign.
Overvoltage-tolerant inputs	Eliminates need for external series resistors or clamps when interfacing with 5.5 V sensors or buses.
Symmetrical output impedance	Ensures matched rise/fall times (<10% skew) for clean clock inversion and signal conditioning.
Low dynamic power dissipation	CPD = 10 pF per buffer - reduces switching current in high-frequency enable/control lines.
High ESD robustness	HBM >2000 V, CDM >1000 V - improves manufacturing yield and field reliability in handling-sensitive environments.

Applications

Use Scenario: Cleaning and inverting noisy 5 V trigger pulses from bench instruments before feeding into FPGA capture logic.

IC Role / Device Role / Timing Role: Noise-immune inverter stage with high VIH/VIL margins rejecting sub-100 ns glitches.

Use Value: 2.0 V VIH and 0.8 V VIL provide >1.2 V noise margin; ±8 mA drive sustains signal integrity into 50 Ω scope inputs.

Use Scenario: Isolating digital control signals between a 5 V analog front-end ASIC and a 3.3 V safety-monitoring MCU.

IC Role / Device Role / Timing Role: Galvanically isolated logic inverter (used with optocoupler input side) ensuring fault-free reset sequencing.

Use Value: –40 °C to +125 °C rating supports operation near heat-generating analog sections; low ICC <40 μA minimizes standby power draw.

Equivalent & Alternatives

The following parts are listed as comparable options for similar triple inverter applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
74AHCT3G04DC	VSSOP8 package (2.3 mm width); 0.65 mm lead pitch; higher thermal resistance than XSON8.	Requires larger PCB area; better suited for hand-soldering or prototyping vs. automated high-density assembly.	Select when board assembly process lacks XSON8 reflow capability or when thermal margin exceeds 68 °C is not required.
SN74LVC3G04DCUR	CMOS input thresholds (VIH = 2.0 V @ VCC = 3.3 V); 1.65–5.5 V supply; lower drive (±24 mA).	Not TTL-compatible; unsuitable for direct 5 V legacy interface without external biasing.	Choose only if system uses uniform 3.3 V logic and requires wider supply flexibility, not TTL interoperability.

Compared with 74AHCT3G04DC, the 74AHCT3G04GD,125 offers 30% smaller footprint and superior thermal performance above 68 °C; versus SN74LVC3G04DC, it guarantees native TTL input compatibility but sacrifices multi-supply flexibility.

FAQ

Is 74AHCT3G04GD,125 compatible with 3.3 V microcontroller outputs?

No - its TTL input thresholds require ≥2.0 V for HIGH recognition, making it incompatible with 3.3 V CMOS outputs that swing only to ~1.7 V (V_OH min). It is designed specifically for 5 V systems or level translation from 5 V to lower-voltage logic, not the reverse.

What is the maximum allowable junction temperature for continuous operation?

The device is rated for operation up to +125 °C ambient, with junction temperature limited by package thermal resistance and power dissipation. For XSON8 (SOT833-1), P_tot derates linearly at 3.1 mW/K above +68 °C; at 125 °C ambient, maximum usable power drops to ~72 mW assuming typical θ_JA.

Can this part drive a 50 Ω transmission line directly?

Yes - with ±8 mA output drive at V_CC = 4.5 V, it can source/sink sufficient current to terminate a 50 Ω line at ~0.4 V swing (8 mA × 50 Ω), though signal integrity beyond 10 cm may require external series termination due to limited edge rate control.

Does the XSON8 package support reflow soldering per JEDEC J-STD-020?

Yes - the XSON8 (SOT833-1) package is qualified for standard lead-free reflow profiles, including peak temperatures up to 260 °C for 10 seconds. Its 0.35 mm terminal pitch and exposed pad-less structure require precise stencil design and placement accuracy.
