Nexperia USA Inc. 74ALVC374D,112

Overview

74ALVC374D,112 from Nexperia is an octal positive-edge-triggered D-type flip-flop with 3-state outputs in SO20 (SOT163-1) package, operating from 1.65 V to 3.6 V supply, featuring IOFF partial power-down protection, Schmitt-trigger inputs for noise immunity, and -40 °C to +125 °C temperature rating - used in bus interface buffering and data latching in industrial control logic.

For engineers reviewing the 74ALVC374D,112 datasheet, 74ALVC374D,112 pinout, 74ALVC374D,112 application, or 74ALVC374D,112 equivalent, key selection criteria include edge-triggered register timing (tsu = 0.8 ns min), 3-state enable latency (ten = 1.0–4.6 ns), IOFF-enabled system-level power sequencing, and compatibility with mixed-voltage TTL/CMOS buses.

Technical Context

This device implements eight independent D-type flip-flops synchronized on the LOW-to-HIGH transition of CP, with asynchronous 3-state control via active-low OE. Each flip-flop samples its D-input only at clock edges meeting setup/hold time requirements (tsu/th ≥ 0.7 ns at VCC = 3.3 V).

The IOFF circuit disables outputs when VCC = 0 V, blocking backflow current during partial power-down; Schmitt-trigger inputs tolerate slow signal edges (Δt/ΔV down to 10 ns/V at VCC = 3.6 V), enabling robust operation in noisy industrial environments.

FAQ

Does 74ALVC374D,112 support hot-plug operation with VCC = 0 V?

Yes. Its IOFF circuitry actively disables outputs and limits back-current to ±10 μA maximum when VCC = 0 V, enabling safe insertion into live backplanes or multi-rail systems without damaging upstream drivers or downstream loads.

Can OE be toggled asynchronously while CP is active?

Yes. The OE input operates independently of the clock; asserting OE HIGH places Q0–Q7 into high-impedance state immediately (ten ≤ 4.6 ns), without altering stored flip-flop states or requiring clock synchronization.

What is the minimum pulse width required on CP for reliable operation?

The minimum CP pulse width is 1.0 ns at VCC = 3.3 V (3.3 ns at VCC = 1.65 V). This ensures sufficient time for internal metastability resolution and guarantees deterministic sampling of D-inputs on the rising edge.

Is the SO20 package RoHS-compliant and lead-free?

Yes. The SOT163-1 package used for 74ALVC374D,112 is fully RoHS-compliant and lead-free, with matte tin (Sn) termination finish, qualified per JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) for unlimited floor life at ≤30 °C/60% RH.
