Nexperia USA Inc. 74LVC374APW,118

Overview

74LVC374APW,118 from Nexperia is an octal positive-edge-triggered D-type flip-flop with 3-state outputs, designed for data latching and bus isolation in mixed-voltage digital systems. It operates from 1.2 V to 3.6 V supply, accepts 5.5 V-tolerant inputs, features IOFF partial power-down protection, and delivers ≤9.0 ns propagation delay at 3.3 V - enabling reliable use in industrial control backplanes and FPGA I/O expansion interfaces.

For engineers reviewing the 74LVC374APW,118 datasheet, 74LVC374APW,118 pinout, 74LVC374APW,118 application, or 74LVC374APW,118 equivalent, this device serves as a voltage-translating 8-bit register with precise set-up/hold timing (2.0 ns / 1.5 ns at 3.3 V), Schmitt-trigger input noise immunity, and guaranteed high-impedance output disable during power sequencing.

Technical Context

The 74LVC374APW,118 implements eight independent D-type flip-flops sharing a common clock (CP) and active-low output enable (OE). Each flip-flop captures Dn on the LOW-to-HIGH CP edge, while OE independently controls all eight outputs without affecting internal state storage.

Its IOFF circuitry disables outputs when VCC = 0 V, blocking backflow current during partial power-down. Schmitt-trigger inputs ensure robust operation with slow-rising signals, and 5.5 V input tolerance enables direct interfacing between 3.3 V logic and legacy 5 V peripherals.

FAQ

What is the maximum clock frequency supported by the 74LVC374APW,118?

The 74LVC374APW,118 supports up to 150 MHz maximum clock frequency at VCC = 3.3 V and Tamb = 25 °C, with derating to 120 MHz over the full −40 °C to +125 °C operating range. This is determined by its 1.5 ns minimum clock pulse width and 9.0 ns propagation delay, ensuring reliable edge-triggered capture under worst-case conditions.

Can the 74LVC374APW,118 safely interface between a 3.3 V microcontroller and a 5 V display module?

Yes - its 5.5 V-tolerant inputs allow direct connection of 5 V display control/data lines to D0–D7 and CP/OE, while its 3.3 V-compatible outputs (Q0–Q7) drive the microcontroller's 3.3 V inputs. No external level shifters are needed, provided VCC is supplied at 3.3 V and OE is actively controlled.

Does the 74LVC374APW,118 support hot-swap or partial power-down operation?

Yes - its integrated IOFF circuitry disables outputs and limits leakage to ±10 μA when VCC = 0 V, preventing backflow current from live 5 V buses into unpowered logic. This enables safe insertion/removal in modular systems and supports power-gating strategies in energy-sensitive designs.

How does the Schmitt-trigger input improve noise immunity in real-world PCB layouts?

Schmitt-trigger inputs provide hysteresis (typically 0.3–0.5 V) that rejects noise spikes below the threshold window, allowing reliable operation with slow-rising signals (down to 10 ns/V slew rate) and long traces susceptible to crosstalk or EMI - eliminating false triggering in electrically noisy industrial enclosures.
