Product details
Overview
74LVC374APW-Q100 from Nexperia is an automotive-grade octal positive-edge-triggered D-type flip-flop with 3-state outputs, 1.2 V to 3.6 V supply range, 5.5 V overvoltage-tolerant inputs/outputs, and IOFF partial power-down protection. It operates from −40 °C to +125 °C and serves as a level-translating register in mixed-voltage automotive control modules.
For engineers reviewing the 74LVC374APW-Q100 datasheet, 74LVC374APW-Q100 pinout, 74LVC374APW-Q100 application, or 74LVC374APW-Q100 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification, tpd ≤ 7.0 ns at 3.3 V, 8-bit independent register + 3-state buffer operation, and Schmitt-trigger input tolerance for slow-rising signals in noisy vehicle environments.
Technical Context
This device implements eight independent edge-triggered D-flip-flops synchronized to the LOW-to-HIGH transition of CP, with asynchronous 3-state control via active-low OE. Each flip-flop samples its D-input only on clock edges meeting setup (tsu ≥ 2.0 ns) and hold (th ≥ 1.5 ns) requirements.
The IOFF circuit disables outputs when VCC = 0 V, blocking backflow current during partial power-down-critical for automotive domain controllers undergoing sleep/wake transitions. Inputs accept 0–5.5 V regardless of VCC (1.2–3.6 V), enabling direct interfacing between 3.3 V logic and legacy 5 V subsystems without external translators.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 1.2 V to 3.6 V - supports low-power microcontroller I/O domains while maintaining compatibility with 3.3 V systems |
| Input voltage tolerance | 0 V to 5.5 V - enables robust level translation between 3.3 V and 5 V buses without external components |
| Propagation delay (tpd) | ≤ 7.0 ns at VCC = 3.3 V - ensures timing-critical sampling in high-speed automotive data acquisition paths |
| Max operating frequency | 150 MHz at VCC = 3.3 V - supports real-time capture of sensor or bus signals in ADAS pre-processing stages |
| IOFF leakage current | ±10 μA at VCC = 0 V - prevents destructive back-current during hot-swap or power sequencing in ECU modules |
| ESD rating (HBM) | > 2000 V - meets automotive board-level ESD immunity requirements per ISO 10605 |
| Ambient temperature range | −40 °C to +125 °C - qualified for under-hood and transmission-control applications |
Pinout & Package
TSSOP20 package (SOT360-1): 20-pin thin shrink small outline, 4.4 mm body width, lead pitch 0.65 mm, side-wettable flanks for AOI-compatible solder joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Output enable (active LOW) | Asynchronously places all Q outputs in high-impedance state without affecting internal flip-flop states |
| 2 (VCC) | Positive supply | Power rail for logic core and output buffers; IOFF protection activates when VCC = 0 V |
| 3–4, 7–8, 13–14, 17–18 (D0–D7) | Data inputs | Eight asynchronous inputs sampled on CP rising edge; tolerate 5.5 V regardless of VCC |
| 5–6, 9, 12, 15–16, 19 (Q0–Q7) | 3-state outputs | Octal registered outputs; driven HIGH/LOW or tri-stated based on OE and CP timing |
| 10 (GND) | Ground reference | 0 V return path for supply and signal integrity; decoupling capacitor placement critical near Pin 10 |
| 11 (CP) | Clock input | Edge-sensitive trigger; LOW-to-HIGH transition latches Dn values meeting tsu/th timing windows |
| 20 (VCC) | Positive supply (duplicate) | Second supply pin for improved power distribution and reduced IR drop across die |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for −40 °C to +125 °C operation in safety-critical automotive ECUs without derating |
| IOFF partial power-down | Prevents reverse current flow when VCC is off but I/O lines remain energized-essential for domain controller sleep modes |
| Schmitt-trigger inputs | Enables reliable operation with slow-rising signals (e.g., from mechanical switches or long harnesses) without external hysteresis |
| Independent register & buffer control | Flip-flop states persist during OE assertion-allows data retention while isolating downstream loads |
| JEDEC-compliant voltage interfaces | Meets JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), and JESD8-C/JESD36 (2.7–3.6 V) standards for interoperability |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC374AQPWRQ1 | TI variant with identical pinout, same AEC-Q100 Grade 1 rating, but higher ICC (max 40 μA vs. Nexperia's 10 μA at 3.6 V) | Higher static current may impact battery-drain-critical modules like keyless entry receivers | Select when TI ecosystem alignment or existing TI design reuse outweighs ultra-low quiescent current needs |
| 74LVCH374A-Q100 | Nexperia's enhanced version with bus-hold (no external pull-ups needed) and slightly faster tpd (6.5 ns vs. 7.0 ns at 3.3 V) | Bus-hold eliminates need for external bias resistors on unused inputs-reducing component count in sparse I/O designs | Prefer for new designs requiring simplified layout and guaranteed input state retention without external components |
Compared with SN74LVC374AQPWRQ1, the 74LVC374APW-Q100 offers lower static power for always-on automotive nodes; versus 74LVCH374A-Q100, it lacks bus-hold but provides proven cost-optimized performance where input biasing is already managed externally.

FAQ
Is the 74LVC374APW-Q100 compatible with 5 V TTL logic inputs?
Yes. Its inputs are overvoltage tolerant up to 5.5 V and directly interface with TTL-level signals (0.8 V VIH, 2.0 V VOH) across the full 1.2–3.6 V supply range. No level-shifting circuitry is required when connecting to legacy 5 V microcontrollers or sensors, simplifying mixed-voltage board design.
What is the function of the IOFF feature, and when does it activate?
The IOFF circuit automatically disables all outputs when VCC drops to 0 V, preventing damaging backflow current from live I/O lines into the unpowered device. It activates during power-down sequences, hot-swap events, or brown-out conditions-critical for automotive domain controllers that manage partial sleep states without disconnecting peripheral buses.
Can the 74LVC374APW-Q100 operate reliably at 125 °C junction temperature?
Yes. It is fully characterized and qualified for continuous operation from −40 °C to +125 °C ambient temperature per AEC-Q100 Grade 1. Dynamic parameters-including tpd (≤ 9.0 ns), tsu (≥ 2.0 ns), and th (≥ 1.5 ns)-are guaranteed across this range, with thermal derating applied only above 100 °C for TSSOP20 package power dissipation.
How does the Schmitt-trigger input action benefit automotive applications?
Schmitt-trigger inputs provide hysteresis (typically 0.3–0.5 V threshold separation), making the device immune to noise-induced glitches on long harness runs or from inductive loads like solenoids and relays. This eliminates false triggering in engine bay or chassis-mounted modules where EMI is severe and signal rise times are degraded.
