Product details

Overview

74ALVC125D-Q100 from Nexperia is an automotive-qualified quad non-inverting 3-state buffer/line driver in SO14 (SOT108-1) package, operating from 1.65 V to 3.6 V supply, with Schmitt-trigger inputs, IOFF partial power-down protection, and AEC-Q100 Grade 1 qualification (−40 °C to +125 °C). It enables bidirectional bus isolation in automotive body control modules.

For engineers reviewing the 74ALVC125D-Q100 datasheet, 74ALVC125D-Q100 pinout, 74ALVC125D-Q100 application, or 74ALVC125D-Q100 equivalent, key selection criteria include 3-state timing (t_en/t_dis ≤ 4.0 ns at 3.3 V), overvoltage-tolerant inputs (3.6 V), IOFF-enabled safe power sequencing, and SO14 package compatibility with legacy PCB footprints.

Technical Context

This device implements four independent non-inverting buffers, each with active-low 3-state enable (nOE) controlling high-impedance output states. Schmitt-trigger inputs ensure robust noise immunity against slow-rising signals common in automotive wiring harnesses.

The IOFF circuit actively disables outputs when V_CC = 0 V, blocking backflow current up to ±50 mA and enabling hot-insertion and partial power-down operation-critical for domain controller power gating and ECU sleep/wake transitions.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply voltage	1.65 V to 3.6 V - supports dual-rail systems and direct interface with 1.8 V, 2.5 V, and 3.3 V logic domains
Operating temperature	−40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and powertrain applications
Propagation delay	1.1–3.2 ns (V_CC = 3.0–3.6 V) - enables high-speed bus buffering without timing closure issues in CAN/LIN gateway interfaces
Enable/disable time	t_en/t_dis ≤ 4.0 ns (V_CC = 3.0–3.6 V) - ensures precise bus arbitration window control in multiplexed sensor networks
IOFF leakage	±10 μA max at V_CC = 0 V - prevents cross-current during power sequencing in multi-voltage ECUs
Input tolerance	3.6 V overvoltage tolerant - allows direct connection to 3.3 V buses without level shifters, even when V_CC = 1.8 V
ESD rating	HBM > 2000 V, CDM > 1000 V - meets automotive system-level ESD robustness requirements per ISO 10605

Pinout & Package

74ALVC125D-Q100 uses the SO14 plastic small outline package (SOT108-1), 14-pin, 3.9 mm body width, with standard lead pitch (1.27 mm) and gull-wing leads compatible with automated optical inspection and reflow soldering.

Pin	Circuit Role	Design Meaning
1, 4, 10, 13	nOE (active-low output enable)	Independent per-buffer control: LOW enables output; HIGH forces high-impedance state for bus sharing
2, 5, 9, 12	nA (data input)	Schmitt-trigger input with hysteresis - rejects noise on long traces in vehicle chassis environments
3, 6, 8, 11	nY (buffered output)	Non-inverting, 3-state CMOS output capable of driving 24 mA sink/source - suitable for LED indicators and relay drivers
7	GND	Signal reference ground - must be connected to low-impedance chassis ground plane to maintain noise immunity
14	V_CC	Single-supply rail - decoupling capacitor (100 nF ceramic) required within 5 mm for stable switching performance

Key Features

Feature	Design Value
AEC-Q100 Grade 1 qualification	Validated for −40 °C to +125 °C operation with full parametric testing - eliminates need for additional automotive qualification effort
IOFF partial power-down	Outputs disabled with zero V_CC; blocks backflow current up to ±50 mA - enables safe integration into power-gated subsystems
Schmitt-trigger inputs	Typical hysteresis ≈ 0.3 V at V_CC = 3.3 V - suppresses contact bounce and EMI-induced glitches on switch/sensor inputs
Overvoltage-tolerant inputs	Accepts 3.6 V signals regardless of V_CC (1.65–3.6 V) - simplifies mixed-voltage board design and eliminates external clamping diodes
Multiple package options	SO14 (SOT108-1), TSSOP14 (SOT402-1), DHVQFN14 (SOT762-1) - enables footprint scalability from prototyping to space-constrained automotive modules

Applications

Body Control Module (BCM)

Instrument Cluster Interface

Use Scenario: Isolating LIN bus transceiver I/O from microcontroller GPIO during sleep mode.

IC Role / Device Role / Timing Role: 3-state buffer enabling dynamic bus contention control and IOFF-assisted power gating.

Use Value: Eliminates wake-up false triggers by blocking leakage paths when MCU core is powered down, reducing quiescent current below 100 μA.

Use Scenario: Level-shifting and buffering analog/digital signals between 3.3 V cluster MCU and 5 V backlight drivers.

IC Role / Device Role / Timing Role: Non-inverting line driver with overvoltage-tolerant inputs handling mixed-supply signal routing.

Use Value: Removes need for discrete level translators; Schmitt inputs reject PWM noise from backlight dimming circuits.

ADAS Camera Power Sequencing

Electric Power Steering (EPS) Sensor Hub

Use Scenario: Controlling power-enable signals to image sensor and ISP during cold-boot sequence.

IC Role / Device Role / Timing Role: Quad buffer synchronizing multiple power-rail enable lines with matched propagation delay.

Use Value: Ensures monotonic power-up across camera subsystems; t_pd matching < ±0.3 ns minimizes inter-rail skew.

Use Scenario: Multiplexing torque and position sensor data onto shared SPI bus while isolating fault conditions.

IC Role / Device Role / Timing Role: 3-state bus driver enabling sensor hot-swap and diagnostic isolation via OE-controlled disable.

Use Value: Per-sensor enable/disable allows real-time fault containment without resetting entire EPS controller.

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad 3-state buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC125APWR	Industrial grade (−40 °C to +85 °C); no AEC-Q100 qualification; identical SO14 pinout and logic function	Lacks automotive qualification and IOFF - unsuitable for power-gated ECU modules requiring hot-swap safety	Select only for non-automotive industrial control where AEC-Q100 and IOFF are not required.
74LVC125ABQ-Q100	DHVQFN14 (SOT762-1) package; same AEC-Q100 Grade 1 spec; 2.5 × 3 mm footprint with side-wettable flanks	Enables higher-density layout and AOI-compatible solder joints - preferred for new automotive designs targeting IPC-A-610 Class 3 reliability	Choose for next-gen compact modules where thermal performance and automated optical inspection are mandatory.

Compared with SN74LVC125APWR, the 74ALVC125D-Q100 adds automotive qualification and IOFF; compared with 74LVC125ABQ-Q100, it retains legacy SO14 compatibility but sacrifices thermal efficiency and AOI capability.

FAQ

Can 74ALVC125D-Q100 operate with V_CC = 1.8 V while interfacing with 3.3 V peripherals?

Yes. Its inputs are overvoltage tolerant up to 3.6 V regardless of V_CC, allowing direct connection to 3.3 V buses without level shifters. At V_CC = 1.8 V, VIH is 1.17 V and VOL is ≤0.3 V (IO = 12 mA), ensuring noise margins exceed 0.4 V for reliable 3.3 V logic detection.

What is the maximum capacitive load this device can drive while maintaining specified t_pd?

The datasheet specifies t_pd with 30 pF (V_CC ≤ 2.7 V) or 50 pF (V_CC ≥ 3.0 V) load. Driving >50 pF increases propagation delay nonlinearly; for 100 pF loads, t_pd degrades by ~35% at 3.3 V. Use series termination or buffer fanout limiting for heavy loads.

How does IOFF protect during partial power-down in a multi-rail ECU?

When V_CC = 0 V, IOFF disables all outputs, limiting OFF-state leakage to ±10 μA (max) even with 3.6 V applied to inputs or outputs. This prevents destructive backflow current through powered-down sections, satisfying ISO 16750-2 power interruption test requirements.

Is the SO14 package (SOT108-1) pinout identical across all 74ALVC125-Q100 variants?

Yes. All variants (D-Q100, PW-Q100, BQ-Q100) share identical logic functionality and pin numbering. The SO14 (SOT108-1), TSSOP14 (SOT402-1), and DHVQFN14 (SOT762-1) packages maintain consistent pin assignments - enabling drop-in replacement during design iteration or cost optimization.
