Product details

Overview

74AHC1G07GV,125 from Nexperia is a single-channel CMOS buffer with open-drain output, designed for level translation and wired-OR bus interfacing in mixed-voltage systems. It operates from 2.0 V to 5.5 V, tolerates input voltages up to 5.5 V independent of supply, and delivers guaranteed 8 mA sink capability at V_CC = 4.5 V. Used in I²C bus pull-up interfaces and GPIO voltage translation between 3.3 V microcontrollers and 5 V peripherals.

For engineers reviewing the 74AHC1G07GV,125 datasheet, 74AHC1G07GV,125 pinout, 74AHC1G07GV,125 application, or 74AHC1G07GV,125 equivalent, this device serves as a robust, low-power, overvoltage-tolerant buffer for bidirectional signal conditioning, bus driving, and logic-level adaptation across industrial control, sensor interface, and embedded communication subsystems.

Technical Context

The 74AHC1G07GV implements a non-inverting buffer stage with an open-drain output stage, requiring an external pull-up resistor to define the high logic level. Its input structure supports overvoltage tolerance up to 5.5 V regardless of V_CC, enabling safe interfacing between higher-voltage domains (e.g., 5 V) and lower-supply logic (e.g., 3.3 V or 2.5 V).

Propagation delays are specified down to 2.5 ns (typ.) at V_CC = 5.0 V with 15 pF load, and static characteristics include VIH ≥ 3.85 V and VIL ≤ 1.65 V at V_CC = 5.5 V. The device is fully characterized from −40 °C to +125 °C and meets JESD78 Class II Level A latch-up immunity (>100 mA).

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	2.0 V to 5.5 V - Enables operation across 2.5 V, 3.3 V, and 5 V logic families without level shifters.
Input Voltage Tolerance	Up to 5.5 V - Allows direct connection of 5 V signals to inputs even when V_CC = 2.0 V or 3.3 V.
Output Sink Current	8.0 mA at V_CC = 4.5 V - Sufficient to drive standard I²C bus capacitance (400 pF) with typical pull-up resistors.
t_PZL/t_PLZ	2.5–7.0 ns (typ./max) - Supports >100 MHz toggle rates in low-capacitance applications like sensor data lines.
Operating Temperature	−40 °C to +125 °C - Qualified for under-hood automotive modules, industrial PLC I/O, and high-ambient embedded systems.
ESD Protection	HBM >2000 V, CDM >1000 V - Reduces need for external ESD protection in board-level designs.
Power Dissipation	250 mW max (T_amb ≤ 72 °C) - Enables use in space-constrained SC-74A (SOT753) packages without thermal derating concerns.

Pinout & Package

74AHC1G07GV is housed in the SC-74A (SOT753) surface-mount package: 5-terminal, plastic, 1.7 mm × 1.3 mm body, 0.65 mm lead pitch, with pin 1 index located below the marking "A07" on the lower-left corner.

Pin/Terminal	Circuit Role	Design Meaning
1	Not connected (n.c.)	No internal connection - must be left floating or grounded; no routing required.
2	Data input (A)	CMOS-compatible input accepting 0–5.5 V; overvoltage tolerant and high-impedance (≤0.1 μA leakage).
3	Ground (GND)	Reference node for all input/output thresholds and power return path; requires low-inductance PCB connection.
4	Data output (Y)	Open-drain NMOS output - sinks current only; requires external pull-up to define HIGH state voltage level.
5	Supply voltage (V_CC)	Core logic supply (2.0–5.5 V); decoupling capacitor (100 nF) recommended within 3 mm of this pin.

Key Features

Feature	Design Value
Wide V_CC range	2.0 V to 5.5 V - Eliminates need for separate voltage translators in multi-rail systems.
Overvoltage-tolerant inputs	5.5 V absolute max, independent of V_CC - Enables safe 5 V-to-3.3 V GPIO bridging without external clamping diodes.
Open-drain output architecture	True wired-OR capability - Supports shared-bus topologies (e.g., I²C, SMBus, interrupt lines) with multiple drivers.
High noise immunity	Typical V_IH − V_IL > 2.2 V at V_CC = 5.5 V - Resists EMI-induced false triggering in noisy industrial environments.
Low dynamic power	CPD = 5 pF - Limits switching power to <10 μW at 1 MHz, critical for battery-powered sensor nodes.

Applications

I²C Bus Level Translation

GPIO Voltage Translation

Use Scenario: Interfacing a 3.3 V microcontroller I²C master with 5 V slave peripherals on a shared SDA/SCL bus.

IC Role / Device Role / Timing Role: Acts as bidirectional open-drain buffer on both SDA and SCL lines, enabling voltage domain isolation while preserving timing integrity.

Use Value: Eliminates discrete MOSFET translators; maintains I²C timing compliance (t_BUF, t_F) with 2.5 ns propagation delay and 8 mA sink strength.

Use Scenario: Connecting a 5 V analog sensor's digital alert output to a 3.3 V MCU GPIO configured as an interrupt input.

IC Role / Device Role / Timing Role: Provides level-shifted, overvoltage-safe signal conditioning with fast edge response and no DC loading on the sensor side.

Use Value: Prevents damage to MCU inputs during sensor power-up sequencing; supports <100 ns pulse detection via sub-3 ns propagation delay.

Wired-OR Interrupt Aggregation

Industrial Sensor Interface

Use Scenario: Combining fault signals from multiple 24 V industrial sensors onto a single 3.3 V MCU interrupt line using pull-up to 3.3 V.

IC Role / Device Role / Timing Role: Serves as isolated open-drain OR gate per sensor channel, preventing backfeeding and ensuring fail-safe LOW-active assertion.

Use Value: Enables hot-plug compatibility and fault containment; leverages 100 mA latch-up immunity to survive transient overcurrent events.

Use Scenario: Conditioning digital outputs from RS-485 transceivers or isolated temperature sensors operating at 5 V into a 3.3 V FPGA I/O bank.

IC Role / Device Role / Timing Role: Functions as a robust, temperature-stable (−40 °C to +125 °C) interface buffer with minimal propagation skew.

Use Value: Guarantees signal integrity across wide temperature ranges; eliminates timing jitter from input threshold variation (VIH/VIL stable over full temp range).

Equivalent & Alternatives

The following parts are listed as comparable options for similar buffer-with-open-drain-output applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC1G07DBVR	Lower V_CC min (1.65 V), but input tolerance limited to V_CC + 0.5 V - not overvoltage tolerant.	Restricted to same-supply-domain translation; unsuitable for 5 V → 3.3 V input bridging without external clamping.	Select when operating exclusively in 1.8 V/3.3 V systems and lowest quiescent current (<1 μA) is prioritized.
74LVC1G07GW,125	Same pinout (TSSOP5), identical function, but rated only to +85 °C ambient - not qualified for extended temperature operation.	Not suitable for under-hood automotive or high-temp industrial enclosures where +125 °C operation is required.	Choose only for cost-sensitive commercial-grade applications where full −40 °C to +125 °C qualification is unnecessary.

Compared with SN74LVC1G07DBVR and 74LVC1G07GW,125, the 74AHC1G07GV,125 uniquely combines overvoltage-tolerant inputs, extended temperature rating, and SC-74A packaging - making it the sole option for robust, mixed-voltage, high-ambient industrial signal conditioning without design compromises.

FAQ

Can 74AHC1G07GV,125 drive an I²C bus directly?

Yes - its open-drain output and 8 mA sink capability at V_CC = 4.5 V meet I²C Standard Mode (100 kbps) and Fast Mode (400 kbps) requirements when paired with appropriate pull-up resistors (e.g., 2.2 kΩ to 3.3 V). Propagation delay (≤7 ns) ensures timing compliance even with 400 pF bus capacitance.

Is external pull-up resistor mandatory for Y pin operation?

Yes - the Y pin is an open-drain NMOS output with no internal pull-up. An external resistor to a defined voltage rail (e.g., 3.3 V or 5 V) is required to establish the HIGH logic level. Typical values range from 1 kΩ (for speed-critical buses) to 10 kΩ (for low-power wake-up lines).

What is the significance of the "n.c." pin (Pin 1) in SC-74A package?

Pin 1 is unconnected internally and electrically isolated. It must remain unconnected on the PCB - neither tied to GND nor V_CC. This pin serves solely as a mechanical alignment marker and does not affect functionality or thermal performance.

Does 74AHC1G07GV,125 support hot-swap or live-insertion scenarios?

Yes - its overvoltage-tolerant inputs (up to 5.5 V) and latch-up immunity (>100 mA) allow safe connection to powered-backplane systems. When V_CC is off, inputs remain protected, and the output enters high-impedance state, preventing backfeeding into upstream circuitry.
