Nexperia USA Inc. 74AVC16373DGG,518

Overview

74AVC16373DGG,518 from Nexperia is a 16-bit D-type transparent latch with dual 8-bit sections, 3-state true outputs, 1.2 V to 3.6 V supply operation, 3.6 V I/O tolerance, and dynamic controlled output (DCO) for noise reduction. It serves as a bus interface latch in high-speed digital systems requiring level translation and transient noise suppression - e.g., in FPGA-to-ASIC data path buffering.

For engineers reviewing the 74AVC16373DGG,518 datasheet, 74AVC16373DGG,518 pinout, 74AVC16373DGG,518 application, or 74AVC16373DGG,518 equivalent, key selection criteria include propagation delay at 1.4–3.6 V (0.7–6.8 ns), dual independent latch/enable control per 8-bit section, TSSOP48 package thermal and routing constraints, and DCO-enabled termination line drive without speed penalty.

Technical Context

The device implements two independent 8-bit transparent latch sections, each with dedicated latch enable (LE) and output enable (OE) inputs - enabling selective latching and 3-state control of half-bus segments. Its CMOS architecture supports live insertion via pull-up on nOE and ensures high-impedance during power sequencing.

Dynamic Controlled Output (DCO) circuitry actively modulates output impedance during signal transitions to suppress ringing and ground bounce while maintaining full-speed performance. Low-inductance multiple VCC/GND pins further reduce noise, supporting stable operation up to 3.6 V with sub-3 ns typical propagation delay at 3.3 V.

FAQ

Is 74AVC16373DGG,518 compatible with 1.2 V core logic while driving 3.3 V bus lines?

Yes. The device operates from 1.2 V to 3.6 V and features 3.6 V-tolerant I/Os - meaning inputs accept up to 3.6 V regardless of VCC, and outputs drive valid logic levels into 3.3 V loads when VCC ≥ 2.3 V. This enables seamless level translation without external buffers.

How does Dynamic Controlled Output (DCO) improve signal integrity?

DCO dynamically lowers output impedance during signal transitions to dampen ringing caused by transmission-line effects, then restores full drive strength afterward. Measured data shows reduced overshoot (<10 % VCC) and faster settling without increasing propagation delay - verified in Figure 5 of the datasheet.

What is the recommended power-up sequence to avoid bus contention?

Apply VCC first, then assert nOE HIGH (via 10 kΩ pull-up to VCC) before enabling LE or applying inputs. This ensures all outputs remain in high-impedance until the system is fully powered and controlled - preventing back-driving or short-circuit currents during live insertion.

Can both 8-bit sections operate independently in terms of latching and output control?

Yes. Section 1 (pins 1D0–1D7, 1Q0–1Q7, 1LE, 1OE) and Section 2 (pins 2D0–2D7, 2Q0–2Q7, 2LE, 2OE) have fully independent latch enable and output enable inputs. This allows asynchronous latching of two data words and selective 3-state control - essential for segmented bus arbitration.
