Nexperia USA Inc. 74LVC16374ADGG,512

Overview

74LVC16374ADGG,512 from Nexperia is a 16-bit edge-triggered D-type flip-flop with dual independent 8-bit sections, 3-state outputs, 5 V-tolerant inputs, and operation across 1.2 V to 3.6 V supply. It features two clocks (1CP/2CP), two output enables (1OE/2OE), Schmitt-trigger inputs, and IOFF partial power-down protection. It serves as a bus interface register in mixed-voltage data path synchronization.

For engineers reviewing the 74LVC16374ADGG,512 datasheet, 74LVC16374ADGG,512 pinout, 74LVC16374ADGG,512 application, or 74LVC16374ADGG,512 equivalent, key selection criteria include dual-clock domain isolation, 5 V input tolerance in 3.3 V systems, TSSOP48 thermal performance, and bus hold capability (on LVCH variant, not this LVC version).

Technical Context

This device implements two independent 8-bit positive-edge-triggered D-flip-flop banks, each with dedicated clock and 3-state enable. Inputs accept 0–5.5 V signals regardless of VCC (1.2–3.6 V), enabling level translation between 3.3 V logic and legacy 5 V peripherals without external circuitry.

The IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current during partial power-down. Schmitt-trigger inputs tolerate slow-rising signals (e.g., from mechanical switches or long PCB traces), while multibyte flow-through pinout minimizes signal skew and routing congestion in high-density memory or data bus interfaces.

Key Specifications

Pinout & Package

FAQ

Is the 74LVC16374ADGG,512 pin-compatible with the 74LVCH16374ADGG?

Yes - both share identical TSSOP48 (SOT362-1) pinout, electrical timing, and functional behavior. The only difference is that the LVCH variant includes bus hold circuitry on data inputs, while the LVC version does not. No PCB redesign is needed for substitution where bus hold is not required.

Can this device safely interface a 5 V encoder output with a 3.3 V microcontroller?

Yes - all inputs are 5 V tolerant up to 5.5 V regardless of VCC (1.2–3.6 V). When powered at 3.3 V, the device accepts 0–5 V input signals and drives 3.3 V-compatible outputs, eliminating external level-shifting components in encoder, switch, or sensor interface applications.

What is the purpose of the IOFF feature, and how does it behave during power loss?

IOFF disables outputs when VCC = 0 V, preventing reverse current flow from live I/O lines into the unpowered IC. This protects downstream circuitry during hot-swap events or partial system shutdown - confirmed by specification: IOFF leakage < ±20 μA at VI/VO = 5.5 V and VCC = 0 V.

Does the 74LVC16374ADGG,512 support operation at 1.2 V, and what are the trade-offs?

Yes - guaranteed operation from 1.2 V to 3.6 V. At 1.2 V, maximum frequency drops to 100 MHz (vs. 150 MHz at 3.3 V), and propagation delay increases to 14 ns (vs. 5.4 ns typical at 3.3 V). Static current remains ultra-low (<20 μA), making it ideal for battery-backed real-time clock or low-power monitoring subsystems.
