Product details
Overview
74LVC2G125DP-Q100 from Nexperia is an automotive-grade dual 3-state bus buffer/line driver with independent output enable (nOE) control per channel, 1.65 V to 5.5 V supply operation, ±24 mA output drive at 3.0 V, and Schmitt-trigger inputs for noise immunity-used in CAN/LIN transceiver interface buffering and automotive body control module signal isolation.
For engineers reviewing the 74LVC2G125DP-Q100 datasheet, 74LVC2G125DP-Q100 pinout, 74LVC2G125DP-Q100 application, or 74LVC2G125DP-Q100 equivalent, this device supports mixed-voltage translation between 3.3 V microcontrollers and 5 V legacy peripherals while maintaining AEC-Q100 Grade 1 qualification and IOFF-enabled partial power-down safety in vehicle ECU designs.
Technical Context
This device implements two independent non-inverting buffers, each with active-low 3-state output enable (1OE, 2OE), enabling bidirectional bus control in automotive domain controllers. Each channel accepts overvoltage-tolerant inputs up to 5.5 V and drives outputs across the full 1.65–5.5 V supply range.
Its IOFF circuitry disables outputs and blocks backflow current when VCC = 0 V, satisfying ISO 16750-2 power-off requirements. Schmitt-trigger inputs provide ≥0.35 V hysteresis at 3.3 V, supporting slow-rising signals from sensors or mechanical switches in cabin modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - enables direct interfacing between 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without level shifters |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - sufficient to drive 50 Ω transmission lines or multiple CMOS loads in ADAS sensor hubs |
| Propagation Delay | 0.5 ns to 5.5 ns (VCC = 3.0–3.6 V) - supports >100 MHz data rates in infotainment serial buses |
| IOFF Leakage Current | ±2 μA at VCC = 0 V - prevents battery drain during ECU sleep mode in always-on vehicle networks |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood engine control unit placement per AEC-Q100 Grade 1 |
| Input Hysteresis | ≥0.35 V at VCC = 3.3 V - rejects EMI-induced glitches on door switch or seat position sensor inputs |
| ESD Robustness | HBM >2000 V, CDM >1000 V - withstands assembly handling and in-vehicle electrostatic discharge events |
Pinout & Package
TSSOP8 package (SOT505-2): plastic thin shrink small outline, 8-pin, 3 mm body width, 0.65 mm pitch, lead length 0.5 mm - optimized for automated SMT placement in space-constrained automotive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7 | 1OE, 2OE | Active-low output enable inputs - independently disable each buffer's output to high-impedance state for bus arbitration |
| 2, 5 | 1A, 2A | Data inputs - accept TTL/CMOS levels and tolerate 5.5 V regardless of VCC, enabling mixed-voltage signal routing |
| 3, 6 | 1Y, 2Y | Buffered non-inverting outputs - deliver rail-to-rail swing with ±24 mA sink/source capability at 3.0 V |
| 4 | GND | Ground reference - common return path for all I/O and internal logic; requires low-inductance connection to minimize ground bounce |
| 8 | VCC | Supply voltage input - powers internal logic and output drivers; decoupling capacitor (100 nF) required within 3 mm |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for −40 °C to +125 °C operation and automotive reliability stress tests - meets OEM requirements for powertrain and chassis ECUs |
| IOFF partial power-down | Blocks reverse current flow when VCC is unpowered - eliminates risk of backfeeding into powered subsystems during key-off states |
| Schmitt-trigger inputs | Provides ≥0.35 V hysteresis at 3.3 V - ensures clean logic transitions from noisy analog sensors or long harness runs |
| Overvoltage-tolerant inputs | Accepts up to 5.5 V regardless of VCC setting - allows direct connection to 5 V legacy clusters without external clamping diodes |
| JEDEC-compliant voltage standards | Complies with JESD8-7, JESD8-5, JESD8C, and JESD36 - guarantees interoperability across multi-supply automotive architectures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G125QDCURQ1 | TI part in VSSOP8 (SOT765-1); identical electrical specs but 2.3 mm body width vs. 3 mm | Higher board density possible; same thermal derating (4.9 mW/K above 99 °C) | Select for tighter layout constraints where 0.7 mm narrower footprint is critical |
| 74LVC2G125DC-Q100 | Nexperia's VSSOP8 variant (SOT765-1); identical logic, temp range, and AEC-Q100 rating | Same pinout mapping but smaller package; 0.2 mm thinner profile aids conformal coating coverage | Prefer when board height budget is limited or reflow profile favors thinner packages |
Compared with 74LVC2G125DP-Q100, SN74LVC2G125QDCURQ1 offers identical performance in a 0.7 mm narrower package, while 74LVC2G125DC-Q100 provides identical Nexperia qualification with reduced Z-height-both require layout revision but no schematic change.

FAQ
Is 74LVC2G125DP-Q100 compatible with 5 V TTL inputs while operating at 3.3 V VCC?
Yes. Its inputs are overvoltage tolerant up to 5.5 V regardless of VCC level, allowing direct connection to 5 V TTL outputs without external resistors or level shifters. This is confirmed in Section 2 ("Overvoltage tolerant inputs to 5.5 V") and Table 6 (VI max = 5.5 V in both enable and disable modes).
What is the maximum allowable ambient temperature for continuous operation?
The device is rated for continuous operation from −40 °C to +125 °C, fully qualified per AEC-Q100 Grade 1. Thermal derating begins above 96 °C for the TSSOP8 package, with total power dissipation decreasing linearly at 4.6 mW/K beyond that point, as specified in Table 5 footnote [2].
Does 74LVC2G125DP-Q100 support hot insertion or live bus swapping?
No. While IOFF prevents backfeed during full power-down (VCC = 0 V), the device lacks true hot-swap protection such as slew-rate limiting or undervoltage lockout. It must be powered before applying input signals, as stated in Section 1 ("fully specified for partial power down applications using IOFF") - not hot-plug operation.
Can both buffers be enabled simultaneously without crosstalk or timing skew?
Yes. The functional diagram (Fig. 1) and dynamic characteristics (Table 8) confirm independent channels with matched tpd (propagation delay) and ten/tdis (enable/disable times). Measured skew between channels is ≤0.3 ns under identical load conditions, verified in Table 8's min/max columns for both 1A→1Y and 2A→2Y paths.
