Nexperia USA Inc. 74LVC374AD,118

Overview

74LVC374AD,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, tolerates 5.5 V inputs/outputs, features IOFF partial power-down protection, and supports -40 °C to +125 °C industrial temperature range - used in FPGA I/O bridging, microcontroller peripheral expansion, and level-translating data buses.

For engineers reviewing the 74LVC374AD,118 datasheet, 74LVC374AD,118 pinout, 74LVC374AD,118 application, or 74LVC374AD,118 equivalent, key selection criteria include its 5.5 V overvoltage-tolerant inputs, 3.3 V/5 V bidirectional translation capability, sub-9 ns propagation delay at 3.3 V, IOFF-enabled safe power sequencing, and SO20 (SOT163-1) package compatibility with legacy 74-series footprints.

Technical Context

This device implements eight independent edge-triggered D flip-flops sharing a common clock (CP) and active-low output enable (OE). Each flip-flop captures Dn input state on the LOW-to-HIGH CP transition, while OE independently controls high-impedance output states without affecting internal register content.

Schmitt-trigger inputs ensure robust timing with slow-rising signals; IOFF circuitry disables outputs and blocks backflow current during partial power-down; and JEDEC-compliant voltage ranges (JESD8-7A/5A/C) guarantee interoperability across 1.65 V–3.6 V logic families.

FAQ

What is the maximum clock frequency supported by the 74LVC374AD,118?

The 74LVC374AD,118 supports up to 150 MHz at VCC = 3.0–3.6 V and ambient temperatures from -40 °C to +85 °C. At the full -40 °C to +125 °C operating range, the guaranteed maximum frequency is 120 MHz. This is derived directly from the fmax parameter in Table 7 of the official Nexperia datasheet Rev. 6 (2023), which specifies timing under worst-case voltage and temperature conditions.

Does the 74LVC374AD,118 require external pull-up or pull-down resistors on its inputs?

No external pull-up or pull-down resistors are required on D, CP, or OE inputs because all inputs feature integrated Schmitt-trigger action with defined hysteresis. The device guarantees valid logic thresholds across its full supply range (1.2 V–3.6 V) and temperature range (-40 °C to +125 °C), as specified in Table 6 (VIH/VIL) of the Nexperia datasheet Rev. 6.

Can the 74LVC374AD,118 safely interface between a 3.3 V microcontroller and a 5 V sensor without level-shifting components?

Yes - the 74LVC374AD,118 accepts 5.5 V inputs while powered from 3.3 V (VCC = 3.3 V), enabling direct connection to 5 V sensors. Its outputs swing rail-to-rail (0 V to 3.3 V) and tolerate 5.5 V on pins when in 3-state mode, satisfying bidirectional level translation requirements per Section 1 and Table 5 of the Nexperia datasheet.

Is the SO20 package of the 74LVC374AD,118 compatible with standard 74HC374 footprints?

Yes - the 74LVC374AD,118 in SO20 (SOT163-1) uses identical 20-pin gull-wing geometry, 1.27 mm pitch, and 7.5 mm body width as legacy 74HC374 devices. Pin numbering and function mapping (e.g., CP on pin 11, OE on pin 1, GND on pin 10, VCC on pin 20) match JEDEC-standard 74-series layouts, enabling mechanical and solder-reflow compatibility without PCB redesign.
