Nexperia USA Inc. 74AHC374PW-Q100J

Overview

74AHC374PW-Q100 from Nexperia is an automotive-grade octal positive-edge-triggered D-type flip-flop with 3-state outputs, designed for synchronous data latching and bus isolation in vehicle control units. It operates across 2.0 V to 5.5 V supply, features TTL-compatible inputs (for AHCT variant), supports -40 °C to +125 °C ambient, and delivers 4.4 ns typical propagation delay at 5 V with 15 pF load.

For engineers reviewing the 74AHC374PW-Q100 datasheet, 74AHC374PW-Q100 pinout, 74AHC374PW-Q100 application, or 74AHC374PW-Q100 equivalent, this device serves as a high-reliability, AEC-Q100 Grade 1–qualified register for CAN/LIN interface buffering, ADAS sensor data capture, and powertrain ECU signal synchronization where edge-triggered storage and output disable control are required.

Technical Context

This IC 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 transition of CP, provided setup (3.0 ns min at 5 V) and hold (2.0 ns min) timing requirements are met. OE operates asynchronously: asserting HIGH forces all Q-outputs into high-impedance, without altering internal latch states.

Input tolerance extends to 5.5 V regardless of VCC, enabling mixed-voltage translation between 3.3 V and 5 V domains. Schmitt-trigger inputs enhance noise immunity, while CMOS design ensures low static current (≤80 μA at 5.5 V) and dynamic power dissipation governed by CPD = 10 pF.

FAQ

What is the maximum clock frequency supported by the 74AHC374PW-Q100?

The device supports up to 130 MHz maximum clock frequency at VCC = 4.5–5.5 V with 15 pF load, as specified in Table 7. This value assumes ideal signal integrity; real-world operation depends on PCB layout, termination, and load capacitance. At 50 pF load, fmax drops to 120 MHz due to increased propagation delay.

Can the 74AHC374PW-Q100 interface directly with a 3.3 V microcontroller and a 5 V peripheral?

Yes - its overvoltage-tolerant inputs accept up to 5.5 V regardless of VCC level, allowing safe connection to 5 V peripherals while powered from 3.3 V. Outputs swing rail-to-rail (0 V to VCC), so 3.3 V operation yields 0–3.3 V outputs compatible with 3.3 V MCU inputs.

How does the OE pin behave during power-up or brown-out conditions?

OE is active-low and internally pulled down on power-up per Nexperia's default behavior for this family, ensuring outputs remain in high-impedance until firmware asserts OE = LOW. During brown-out, OE retains its last driven state unless external pull-up/down resistors are added for fail-safe behavior.

Is there a difference in ESD robustness between the 74AHC374PW-Q100 and standard commercial versions?

No - the Q100 variant maintains identical ESD ratings: HBM >2000 V and CDM >1000 V per JS-001/JS-002. AEC-Q100 qualification adds stress testing (temperature cycling, HTOL, etc.) but does not alter the fundamental ESD protection circuitry or rating values.
