Product details
Overview
74LVC1G74GD-Q100 from Nexperia is an automotive-grade single D-type flip-flop with asynchronous set (SD) and reset (RD), positive-edge-triggered clock (CP), complementary Q/Q̅ outputs, 1.65 V to 5.5 V supply range, and IOFF partial power-down support. It operates from −40 °C to +125 °C and functions as a synchronous storage element in safety-critical vehicle control logic, such as transmission shift sequencing or ADAS sensor synchronization.
For engineers reviewing the 74LVC1G74GD-Q100 datasheet, 74LVC1G74GD-Q100 pinout, 74LVC1G74GD-Q100 application, or 74LVC1G74GD-Q100 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification, ±24 mA output drive at 3.0 V, 4.1 ns max propagation delay at 5 V, Schmitt-trigger input tolerance for slow-rising signals, and IOFF-enabled backflow prevention during power sequencing.
Technical Context
This device implements a master-slave edge-triggered D flip-flop architecture with priority-governed asynchronous set and reset inputs active LOW. Its dual-mode operation supports both synchronous data capture on CP rising edges and immediate state override via SD/RD independent of clock timing.
The IOFF circuit activates when VCC = 0 V, forcing high-impedance outputs to prevent current backflow in mixed-voltage power-down scenarios. Schmitt-trigger inputs provide hysteresis (typ. 0.3 V at 3.3 V), enabling robust interfacing with noisy or slow-slew microcontroller GPIOs or legacy 5 V logic in automotive body electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 1.65 V to 5.5 V - enables direct interface between 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without level shifters. |
| Propagation delay (tpd) | 1.0 ns to 4.1 ns - ensures sub-5 ns timing margin for 100+ MHz clock domains in engine control units. |
| Output drive strength | ±24 mA at VCC = 3.0 V - drives multiple 74LVC inputs or small capacitive loads (e.g., PCB traces ≤ 20 pF) without buffering. |
| IOFF leakage | ±2 μA at VCC = 0 V - prevents damaging back-current during hot-swap or staggered power-up in multi-rail ECUs. |
| Input hysteresis | Typ. 0.3 V at 3.3 V - rejects noise spikes up to 300 mV on CP, SD, or RD lines in electrically harsh under-hood environments. |
| Operating temperature | −40 °C to +125 °C - qualified for powertrain and chassis applications per AEC-Q100 Grade 1 requirements. |
| ESD protection | HBM > 2000 V, CDM > 1000 V - withstands handling and assembly ESD events common in Tier 1 manufacturing. |
Pinout & Package
XSON8 package (SOT833-1): plastic extremely thin small outline, no leads, 8-terminal surface-mount, 1.0 mm × 1.95 mm × 0.5 mm body, wettable flank compatible for automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RD | Asynchronous reset input (active LOW); forces Q = 0, Q̅ = 1 immediately, overriding CP and D. |
| 2 | SD | Asynchronous set input (active LOW); forces Q = 1, Q̅ = 0 immediately, overriding CP and D. |
| 3 | VCC | Positive supply rail; powers internal logic and output drivers; supports 1.65–5.5 V operation. |
| 4 | Q | True output; reflects stored D value after CP rising edge or SD/RD assertion. |
| 5 | Q̅ | Complementary output; inverted state of Q; enables differential signaling or feedback paths. |
| 6 | D | Data input; sampled on LOW-to-HIGH CP transition if setup/hold times met (min. 1.0 ns hold at 5 V). |
| 7 | CP | Clock input; edge-sensitive; Schmitt-triggered to tolerate slow rise/fall times (>10 ns/V slew rate supported). |
| 8 | GND | Reference ground; return path for all input/output currents; must be low-impedance for noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for −40 °C to +125 °C operation in engine control, braking, and steering systems. |
| IOFF partial power-down | Outputs enter high-Z state when VCC = 0 V, eliminating backfeed risk during system sleep or rail sequencing. |
| Overvoltage-tolerant inputs | Accepts 0–5.5 V signals regardless of VCC level - allows safe interfacing with 5 V sensors while powered from 3.3 V. |
| Schmitt-trigger inputs | Provides ≥0.3 V hysteresis at 3.3 V, rejecting EMI-induced glitches on CP, SD, and RD in high-noise vehicle harnesses. |
| Wide output drive capability | Delivers ±24 mA at 3.0 V - sufficient to drive two 74LVC1G gates or terminate short PCB traces without external buffers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G74DRYR | No AEC-Q100 qualification; rated −40 °C to +85 °C only; identical pinout and electrical specs otherwise. | Restricted to non-safety-critical cabin or infotainment systems; not approved for powertrain or chassis use. | Select when automotive qualification is unnecessary and cost sensitivity outweighs long-term reliability requirements. |
| 74LVC1G74GT-Q100 | Same AEC-Q100 Grade 1 spec and XSON8 footprint but uses SOT833-1 package variant with identical 1×1.95×0.5 mm dimensions and wettable flanks. | Functionally identical; differs only in JEDEC registration code and minor marking - fully interchangeable in layout and BOM. | Prefer for new designs requiring latest package revision traceability; existing 74LVC1G74GD-Q100 boards accept GT-Q100 without change. |
Compared with SN74LVC1G74DRYR, the 74LVC1G74GD-Q100 adds mandatory automotive qualification and extended temperature support, while versus 74LVC1G74GT-Q100 it offers identical functionality in a functionally equivalent XSON8 variant-making GD-Q100 optimal for legacy-replacement or first-sourcing in AEC-compliant powertrain modules.

FAQ
What is the maximum clock frequency supported by the 74LVC1G74GD-Q100?
The device supports up to 200 MHz maximum clock frequency at VCC = 4.5 V to 5.5 V, verified across −40 °C to +125 °C. At lower voltages (e.g., 1.65 V), fmax drops to 80 MHz due to reduced drive strength and increased propagation delay - all values are guaranteed per Table 9 in the official datasheet Rev. 7.
Does the 74LVC1G74GD-Q100 support mixed-voltage interfacing?
Yes - its overvoltage-tolerant inputs accept 0–5.5 V signals regardless of VCC level (1.65–5.5 V), enabling direct connection to 5 V sensors or legacy controllers while operating from 3.3 V or 2.5 V rails. This eliminates external level shifters in gateway or domain controller designs.
How does the IOFF feature protect the device during power sequencing?
When VCC = 0 V, the IOFF circuit disables all outputs, placing them in high-impedance state. This prevents reverse current flow from live I/O lines (e.g., 5 V CP or SD) into the unpowered VCC rail - a critical safeguard during staggered power-up/down in multi-supply automotive ECUs.
Is the XSON8 package of the 74LVC1G74GD-Q100 compatible with automated optical inspection (AOI)?
Yes - the SOT833-1 XSON8 package features wettable flanks and a 0.4 mm pitch, enabling reliable solder-joint inspection using standard AOI systems. The 1.0 mm × 1.95 mm body and exposed terminal sides meet IPC-A-610 Class 3 requirements for automotive production.
