Product details
Overview
74AHCT374D-Q100 from Nexperia is an automotive-grade octal positive-edge-triggered D-type flip-flop with 3-state outputs, TTL-compatible inputs, and overvoltage-tolerant I/O (up to 5.5 V). It operates from 4.5 V to 5.5 V across –40 °C to +125 °C, delivers 8.1 ns max propagation delay at 5 V/15 pF, and supports synchronous data latching in automotive body control modules and infotainment interface buffers.
For engineers reviewing the 74AHCT374D-Q100 datasheet, 74AHCT374D-Q100 pinout, 74AHCT374D-Q100 application, or 74AHCT374D-Q100 equivalent, key selection criteria include edge-triggered register behavior, 3-state output enable timing (9.5 ns max enable time), automotive AEC-Q100 Grade 1 qualification, and TTL-level input compatibility in mixed-voltage signal routing.
Technical Context
This device implements eight independent D-type flip-flops sharing a common clock (CP) and active-low 3-state output enable (OE). Each flip-flop captures the logic state of its D-input on the LOW-to-HIGH CP transition, meeting 3.0 ns minimum setup and 2.0 ns minimum hold time at 5 V. OE controls all eight outputs simultaneously without affecting internal register states.
The 74AHCT374D-Q100 uses TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), enabling direct interfacing with legacy 5 V TTL logic while maintaining CMOS power efficiency. Its overvoltage-tolerant inputs accept up to 5.5 V regardless of VCC, supporting robust level translation in heterogeneous voltage domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Octal D-type flip-flop with 3-state outputs and common clock/enable |
| Supply Voltage Range | 4.5 V to 5.5 V - ensures stable operation in automotive 5 V rail systems with ±10 % tolerance |
| Propagation Delay (tpd) | 9.4 ns max at VCC = 5 V, CL = 15 pF - enables ≤100 MHz synchronous data capture |
| Enable Time (ten) | 12.0 ns max at VCC = 5 V, CL = 50 pF - defines minimum latency when activating output drivers |
| Input Compatibility | TTL-level (VIH ≥ 2.0 V, VIL ≤ 0.8 V) - allows direct connection to 74LS/74F series without level shifters |
| Temperature Range | –40 °C to +125 °C - qualified for under-hood and powertrain control unit environments |

Pinout & Package
74AHCT374D-Q100 is housed in a plastic small outline package (SO20, SOT163-1) with 20 leads and 7.5 mm body width. The package supports surface-mount reflow assembly and provides mechanical robustness for automotive vibration environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | 3-state output enable (active LOW) | Drives all Q outputs into high-impedance state when HIGH; no effect on internal flip-flop states |
| 2–9, 12, 15–16, 19 (Q0–Q7) | 3-state registered outputs | Reflect D-input values captured at last CP rising edge; tri-stated when OE = HIGH |
| 3–4, 7–8, 13–14, 17–18 (D0–D7) | Data inputs | Sampled on LOW-to-HIGH CP transition; require 3.0 ns setup / 2.0 ns hold time at 5 V |
| 10 (GND) | Ground reference | 0 V return path for all internal logic and I/O; must be low-impedance for noise immunity |
| 11 (CP) | Clock input | Positive-edge-triggered; initiates synchronous latching of all D inputs to respective Q outputs |
| 20 (VCC) | Power supply | Primary 4.5–5.5 V supply; decoupling capacitor required near pin for transient current handling |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from –40 °C to +125 °C with full reliability testing per JEDEC standards |
| TTL-compatible input thresholds | VIH = 2.0 V min, VIL = 0.8 V max at 5 V - eliminates need for external level translators with legacy TTL |
| Overvoltage-tolerant I/O | Withstands 5.5 V on any input or output regardless of VCC - prevents damage during hot-swap or bus contention |
| Low dynamic power dissipation | CPD = 12 pF - limits switching power to <1.5 mW at 10 MHz with 5 V supply and 8 toggling outputs |
| High noise immunity | Input hysteresis via Schmitt-trigger action - rejects <1.0 V peak noise on CP and OE lines |

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 | Lower VCC range (1.65–3.6 V); CMOS inputs only; 6.7 ns tpd at 3.3 V | Targeted for 3.3 V ADAS subsystems; not suitable for 5 V legacy interfaces | Select when operating exclusively in 3.3 V domains and requiring lower static current (1 μA ICC) |
| 74LVTH374PW-Q100 | Higher drive strength (±24 mA); same 5 V operation but higher ICC (80 μA typ) | Better suited for driving long PCB traces or capacitive loads >50 pF | Prefer when interfacing with high-capacitance buses or legacy 5 V backplanes requiring stronger output drive |
Compared with SN74LVC374AQPWRQ1, the 74AHCT374D-Q100 provides TTL-compatible inputs essential for 5 V system integration, while versus 74LVTH374PW-Q100 it offers lower power consumption (40 μA ICC max) at equivalent speed-making it optimal for cost-sensitive, thermally constrained automotive modules.

FAQ
What is the maximum clock frequency supported by the 74AHCT374D-Q100?
The 74AHCT374D-Q100 supports a maximum clock frequency of 140 MHz at VCC = 5 V and CL = 15 pF, verified by fmax test conditions in the datasheet. At 50 pF load, the practical limit drops to 130 MHz due to increased propagation delay and output rise/fall time degradation.
Can the 74AHCT374D-Q100 operate with a 3.3 V supply?
No-the 74AHCT374D-Q100 is specified only for 4.5 V to 5.5 V operation per its recommended conditions table. Using 3.3 V violates VIH/VIL thresholds (requires ≥2.0 V high input), risking unreliable latching and undefined output states; the 74LVC374A variant is recommended for 3.3 V systems.
How does the OE pin behave during power-up sequences?
The OE pin is active LOW and has no internal pull-up; it defaults to high-impedance (tri-state) if left floating during power-up. To ensure defined outputs at startup, OE must be actively driven LOW after VCC stabilizes, or externally pulled LOW via a resistor to GND.
Is the 74AHCT374D-Q100 pin-compatible with the 74AHC374D-Q100?
Yes-both share identical SO20 (SOT163-1) pinout, function table, and package dimensions. The key difference is input threshold: 74AHCT374D-Q100 accepts TTL levels (VIH = 2.0 V), while 74AHC374D-Q100 requires CMOS levels (VIH = 3.85 V at 5.5 V), making them electrically interchangeable only in 5 V TTL environments.
