Product details
Overview
74AHC1G125GV-Q100 from Nexperia is a single-channel 3-state bus buffer/line driver with CMOS-level input compatibility, 2.0 V to 5.5 V supply operation, overvoltage-tolerant inputs (up to 5.5 V), and AEC-Q100 Grade 1 automotive qualification. It functions as a unidirectional signal isolator and level translator in mixed-voltage automotive sub-systems such as body control modules and infotainment interfaces.
For engineers reviewing the 74AHC1G125GV-Q100 datasheet, 74AHC1G125GV-Q100 pinout, 74AHC1G125GV-Q100 application, or 74AHC1G125GV-Q100 equivalent, this device supports high-noise-immunity signal routing in 125 °C ambient environments, delivers balanced propagation delays under 7.0 ns at 5 V/50 pF, and enables compact PCB layout via its SC-74A (SOT753) 5-pin surface-mount package.
Technical Context
This device implements a single non-inverting buffer with active-low 3-state output control (OE), enabling bidirectional bus sharing without contention. Its CMOS input threshold ensures compatibility with 3.3 V and 5 V logic families while maintaining rail-to-rail output swing.
Designed for automotive-grade reliability, it features latch-up immunity exceeding 100 mA per JESD78 Class II Level A, HBM ESD protection >2000 V, and CDM ESD protection >1000 V - all validated across −40 °C to +125 °C operating range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus buffer/line driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT1G125GV-Q100 | TTL-compatible input thresholds (VIH = 2.0 V, VIL = 0.8 V at 5 V); identical pinout and package | Preferred where legacy 5 V TTL logic sources drive the buffer | Select when interfacing with older microcontrollers or ASICs using TTL output standards |
| SN74LVC1G125DBVR | Wider industrial temp range (−40 °C to +125 °C), same 5-pin SOT-23 package, but not AEC-Q100 qualified | Suitable for non-automotive industrial or consumer applications requiring identical functionality | Choose for cost-sensitive non-automotive designs where automotive qualification is unnecessary |
Compared with 74AHC1G125GV-Q100, the 74AHCT1G125GV-Q100 offers lower input switching thresholds for TTL source compatibility, while the SN74LVC1G125DBVR provides identical electrical behavior without automotive qualification - enabling trade-offs between qualification assurance, input compatibility, and cost.

FAQ
What is the maximum supply voltage rating for the 74AHC1G125GV-Q100?
The 74AHC1G125GV-Q100 has an absolute maximum supply voltage (VCC) of +7.0 V per IEC 60134 limiting values, but its recommended operating range is 2.0 V to 5.5 V. Operation above 5.5 V voids guaranteed performance and may cause permanent damage. The 74AHC1G125GV-Q100 must be operated within its specified 2.0–5.5 V window for compliance with AEC-Q100 Grade 1 requirements and functional reliability.
Does the 74AHC1G125GV-Q100 support level translation between different supply domains?
Yes, the 74AHC1G125GV-Q100 supports level translation: its inputs tolerate up to 5.5 V regardless of VCC value, allowing connection to higher-voltage signal sources while powered from a lower VCC rail (e.g., 3.3 V). This eliminates external level shifters in mixed-supply systems. The 74AHC1G125GV-Q100 maintains full CMOS output swing referenced to its own VCC, making it ideal for translating 5 V signals into 3.3 V logic domains.
What is the function of Pin 1 (OE) on the 74AHC1G125GV-Q100?
Pin 1 (OE) is the active-low output enable input. When OE is LOW, the 74AHC1G125GV-Q100 passes the input signal from A to Y with non-inverting logic. When OE is HIGH, the output Y enters high-impedance (Hi-Z) state, electrically disconnecting the buffer from the downstream bus. This 3-state capability enables shared-bus architectures and prevents signal contention - a core function of the 74AHC1G125GV-Q100 in automotive multiplexed networks.
Is the 74AHC1G125GV-Q100 pin-compatible with other packages in the same family?
No - the 74AHC1G125GV-Q100 uses the SC-74A (SOT753) package with specific 5-pin layout (OE-VCC-A-GND-Y), which differs from the TSSOP5 (SOT353-1) and XSON5 (SOT8065-1) variants. While functionally identical, mechanical footprint and soldering requirements differ. PCB layout must match SOT753 dimensions (1.3 × 1.7 mm, 0.65 mm pitch); migration to GW or GZ packages requires board redesign. The 74AHC1G125GV-Q100 is not a drop-in replacement across packages.
What ESD protection levels does the 74AHC1G125GV-Q100 provide?
The 74AHC1G125GV-Q100 provides HBM ESD protection exceeding 2000 V (ANSI/ESDA/JEDEC JS-001 Class 2) and CDM ESD protection exceeding 1000 V (ANSI/ESDA/JEDEC JS-002 Class C3). These ratings are verified per AEC-Q100 stress test requirements and ensure robust handling during automated assembly and field operation in automotive environments. The 74AHC1G125GV-Q100 meets stringent electrostatic discharge immunity needed for under-hood and dashboard module integration.
