Product details
Overview
74AHCT374PW-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, features 2.5 ns minimum data setup time, 2.5 ns hold time, and 4.3 ns typical propagation delay (CL = 15 pF), enabling reliable data latching in automotive body control modules.
For engineers reviewing the 74AHCT374PW-Q100 datasheet, 74AHCT374PW-Q100 pinout, 74AHCT374PW-Q100 application, or 74AHCT374PW-Q100 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification, 3-state output enable timing (10.2 ns max disable time), TTL-level input compatibility, and TSSOP20 package suitability for space-constrained engine control unit PCB layouts.
Technical Context
This device implements eight independent edge-triggered D flip-flops sharing a common clock (CP) and active-low 3-state output enable (OE). Its TTL-compatible inputs allow direct interfacing with legacy 5 V logic while maintaining CMOS power efficiency. The OE signal controls all eight outputs simultaneously without affecting internal flip-flop states.
Each flip-flop samples Dn inputs on the LOW-to-HIGH CP transition and holds the value until the next qualifying edge. Outputs enter high-impedance state when OE is HIGH, supporting bus-sharing architectures in automotive gateway ECUs and ADAS domain controllers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | AHCT - TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 5 V) enable mixed-voltage system interfacing. |
| Supply Voltage Range | 4.5 V to 5.5 V - Ensures stable operation under automotive battery transients (e.g., load dump, cold crank). |
| Propagation Delay (tpd) | 4.3 ns (typ) at VCC = 5 V, CL = 15 pF - Supports >100 MHz clock rates in high-speed serial data capture paths. |
| Set-up / Hold Time | 2.5 ns / 2.5 ns - Enables robust timing margin with standard 5 V microcontroller GPIOs driving D inputs. |
| Output Enable Timing | 10.2 ns max disable time (tdis) - Guarantees clean bus release before next master access in shared-memory interfaces. |
| Operating Temperature | –40 °C to +125 °C - Validated for under-hood placement per AEC-Q100 Grade 1 requirements. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Mitigates field-induced failures during vehicle assembly and service. |
Pinout & Package
TSSOP20 package (SOT360-1): plastic thin shrink small outline, 20 leads, 4.4 mm body width, 0.65 mm pitch, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Active-low 3-state output enable | Drives all Q0–Q7 into high-Z when HIGH; no effect on internal flip-flop state. |
| 2 (VCC) | Positive supply | 5 V nominal rail; supports 4.5–5.5 V range for automotive battery voltage variation tolerance. |
| 3–4, 7–8, 13–14, 17–18 (D0–D7) | Data inputs | Asynchronous inputs sampled on rising CP edge; TTL-compatible thresholds simplify interface design. |
| 5–6, 9, 12, 15–16, 19 (Q0–Q7) | 3-state outputs | Driven low/high or high-Z based on OE; overvoltage tolerant to 5.5 V for mixed-rail systems. |
| 10 (GND) | Ground reference | 0 V return path; decoupling capacitor placement adjacent critical for noise immunity. |
| 11 (CP) | Clock input | Edge-sensitive; triggers all flip-flops synchronously on LOW-to-HIGH transition only. |
| 20 (VCC) | Positive supply (duplicate) | Second VCC pin improves power distribution integrity and reduces ground bounce in high-speed switching. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from –40 °C to +125 °C ambient, including temperature cycling and humidity testing. |
| TTL-compatible inputs | VIH = 2.0 V min, VIL = 0.8 V max at VCC = 5 V - eliminates level-shifter requirement when interfacing with legacy 5 V MCUs. |
| Overvoltage-tolerant I/O | Inputs and outputs withstand up to 5.5 V regardless of VCC - enables safe operation in mixed-supply domains (e.g., 3.3 V logic controlling 5 V peripherals). |
| Low dynamic power | CPD = 12 pF - limits switching current and heat generation in densely populated ECU PCBs. |
| High noise immunity | Input hysteresis via Schmitt-trigger action on all pins - rejects EMI-induced glitches on CP and OE lines in noisy vehicle environments. |
Applications
| Body Control Module | Instrument Cluster Interface |

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, 3.3 V only; 5.5 ns tpd (CL = 50 pF) | Requires level translation for 5 V systems; suited for 3.3 V ADAS SoCs with tighter power budgets | Select when operating exclusively at 3.3 V and lower static current (<1 μA ICC) is prioritized over 5 V compatibility. |
| 74AHC374PW-Q100 | CMOS input thresholds (VIH = 3.85 V @ VCC = 5.5 V); identical pinout, package, and timing specs | Not compatible with TTL-level drivers; requires ≥3.85 V input high for guaranteed recognition | Choose only when interfacing with 5 V CMOS sources (e.g., FPGA I/O banks), not legacy 5 V TTL microcontrollers. |
Compared with SN74LVC374AQPWRQ1 and 74AHC374PW-Q100, the 74AHCT374PW-Q100 uniquely bridges 5 V TTL logic domains without external components while maintaining AEC-Q100 Grade 1 compliance - essential for retrofitting legacy automotive electronics with modern microcontrollers.

FAQ
Is the 74AHCT374PW-Q100 pin-compatible with non-automotive versions like 74AHCT374PW?
Yes - the 74AHCT374PW-Q100 shares identical pinout, package (TSSOP20/SOT360-1), and electrical characteristics with industrial-grade 74AHCT374PW. The "-Q100" suffix denotes AEC-Q100 qualification and extended temperature screening; no layout changes are needed for drop-in replacement in automotive designs.
Can OE be toggled asynchronously while CP is active without corrupting stored data?
Yes - the OE input operates independently of the clock. Driving OE HIGH disables outputs to high-impedance without altering the internal state of any flip-flop; stored Q values remain intact and are reasserted immediately upon OE returning LOW, regardless of CP activity.
What is the maximum clock frequency supported at 125 °C ambient?
At VCC = 5.0 V and CL = 50 pF, the maximum operating frequency is 75 MHz over –40 °C to +125 °C. This is derived from the 12.5 ns maximum propagation delay (tpd) and 11.0 ns maximum disable time (tdis), ensuring sufficient timing margin for reliable edge-triggered operation in under-hood environments.
Does the device support hot insertion or live bus connection?
No - while inputs are overvoltage tolerant to 5.5 V, the device lacks explicit hot-swap protection circuitry. Connecting or disconnecting while powered may cause transient current spikes or latch-up. Use external series resistors and RC filters on OE and CP lines if live insertion is required in service scenarios.
