Product details
Overview
74AUP1G125GW-Q100 from Nexperia is a single-channel, automotive-grade 3-state buffer/line driver with Schmitt-trigger inputs, operating across 0.8 V to 3.6 V supply, delivering ultra-low static current (≤1.4 μA at +125 °C), IOFF-enabled partial power-down protection, and AEC-Q100 Grade 1 qualification for under-hood automotive signal routing applications.
For engineers reviewing the 74AUP1G125GW-Q100 datasheet, 74AUP1G125GW-Q100 pinout, 74AUP1G125GW-Q100 application, or 74AUP1G125GW-Q100 equivalent, this device supports low-voltage logic interfacing in battery-supplied ECUs, meets stringent automotive thermal and ESD requirements (HBM >5 kV, CDM >1 kV), and enables robust signal buffering with input hysteresis and high noise immunity.
Technical Context
This device implements a single non-inverting buffer with active-low 3-state output control (OE), where Schmitt-trigger inputs provide ≥0.3×VCC hysteresis to tolerate slow-rising signals in noisy automotive environments. The IOFF circuit ensures bidirectional isolation when VCC = 0 V, preventing backflow current during system power sequencing.
It operates over -40 °C to +125 °C with guaranteed propagation delay ≤4.4 ns (VCC = 3.3 V, CL = 5 pF), enable/disable times ≤5.5 ns, and dynamic power dissipation governed by CPD = 4.2 pF - enabling energy-efficient signal conditioning in always-on domains like CAN/LIN transceiver interfaces and sensor signal chains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 0.8 V to 3.6 V - supports direct interface with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters |
| Max ICC (Tamb = +125 °C) | 1.4 μA - enables multi-year battery operation in low-power automotive wake-up circuits |
| tpd (VCC = 3.3 V, CL = 5 pF) | ≤4.4 ns - sufficient timing margin for 100+ MHz data routing in body control modules |
| IOFF Leakage (VCC = 0 V) | ±0.75 μA - prevents cross-conduction and bus contention during hot-swap or partial power-down |
| ESD Robustness | HBM >5000 V, CDM >1000 V - exceeds AEC-Q100 stress requirements for assembly and field reliability |
| Input Hysteresis | ≥0.3×VCC - rejects noise spikes up to 1 V on 3.3 V buses, eliminating external RC filtering |
| Operating Temperature | -40 °C to +125 °C - qualified for engine compartment and transmission control unit mounting locations |
Pinout & Package
TSSOP5 (SOT353-1) package: plastic thin shrink small outline, 5-lead, 1.25 mm body width, 0.65 mm lead pitch, surface-mount compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Output Enable (active-low) | Asserting low enables Y = A; high forces Y into high-impedance - critical for bus arbitration and shared signal lines |
| 2 (A) | Data Input | Schmitt-trigger input accepts 0–3.6 V logic levels; immune to slow edges and ground bounce in harness wiring |
| 3 (GND) | Ground Reference | 0 V return path for all internal logic and I/O; must be low-inductance connection to minimize switching noise |
| 4 (Y) | Buffered Output | 3-state non-inverting output drives capacitive loads ≤30 pF with <10 % overshoot/undershoot |
| 5 (VCC) | Power Supply | Single supply rail supporting mixed-voltage system integration; IOFF remains functional down to 0 V |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C ambient, including temperature cycling and humidity testing |
| IOFF partial power-down | Disables output and blocks backflow current when VCC = 0 V - essential for safe hot-plug and domain-isolation architectures |
| Schmitt-trigger inputs | Provides ≥0.3×VCC hysteresis - eliminates need for external debouncing in switch/sensor inputs and LIN bus receivers |
| Ultra-low ICC (≤1.4 μA) | Reduces quiescent power in always-on domains such as vehicle security modules and telematics wake-up logic |
| Wide VCC range (0.8–3.6 V) | Enables direct connection to multiple voltage rails without level translation - simplifies PCB layout and BOM |
Applications
| Engine Control Unit Signal Routing | Body Control Module Bus Isolation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer/line driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G125QDBVRQ1 | Higher ICC (max 10 μA at +125 °C); no Schmitt-trigger inputs; same TSSOP5 package | Lacks hysteresis - requires external filtering for noisy sensor inputs; less suitable for direct harness interfacing | Prefer when cost sensitivity outweighs noise immunity needs and supply is stable ≥1.65 V |
| 74LVC1G125GV-Q100 | Same AEC-Q100 Grade 1 rating but wider VCC range (1.65–5.5 V); higher tpd (≤7.5 ns at 3.3 V) | Supports legacy 5 V domains but consumes more power and adds timing margin overhead | Select only if interfacing with 5 V peripherals; otherwise 74AUP1G125GW-Q100 offers superior low-VCC efficiency |
Compared with SN74LVC1G125QDBVRQ1 and 74LVC1G125GV-Q100, the 74AUP1G125GW-Q100 delivers lowest ICC, built-in Schmitt-trigger noise rejection, and optimal timing performance below 2.5 V - making it the preferred choice for modern 1.2 V/1.8 V automotive subsystems.

FAQ
What is the maximum load capacitance supported while maintaining specified tpd?
The datasheet guarantees propagation delay ≤4.4 ns at VCC = 3.3 V with CL = 5 pF. At CL = 30 pF, tpd increases to ≤8.3 ns under same conditions. For designs requiring <5 ns delay, keep total trace + receiver capacitance ≤15 pF and verify with actual layout simulation.
Can OE be left floating in system design?
No - the datasheet explicitly states "input-disable feature allows floating input conditions" applies only to data input A, not OE. OE must be actively driven high or low; floating OE risks undefined output state and violates AEC-Q100 functional safety requirements for deterministic behavior.
Does the IOFF feature work when VCC is ramping during power-up?
Yes - IOFF activates when VCC drops below ~0.2 V and remains active until VCC rises above ~0.5 V. During power-up, the output stays in high-Z until VCC exceeds the minimum functional threshold (0.8 V), preventing glitch-induced bus contention in multi-rail systems.
How does Schmitt-trigger input improve performance in automotive wiring harnesses?
Schmitt-trigger action provides ≥0.3×VCC hysteresis, rejecting noise spikes up to 1 V on 3.3 V lines and tolerating rise/fall times up to 200 ns/V. This eliminates false triggering from inductive kickback in solenoid drivers and EMI coupling in bundled harnesses - verified per ISO 11452-4 test standards.
