Nexperia USA Inc. 74AVC16373DGG,512

Overview

74AVC16373DGG,512 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) circuitry for noise reduction. It serves as a bus interface latch in high-speed digital systems requiring level translation and transient noise suppression, such as memory address/data buffering in low-voltage FPGAs.

For engineers reviewing the 74AVC16373DGG,512 datasheet, 74AVC16373DGG,512 pinout, 74AVC16373DGG,512 application, or 74AVC16373DGG,512 equivalent, key selection criteria include propagation delay at 1.4–3.6 V (0.7–6.8 ns), 3-state enable/disable timing (2.0–9.4 ns), input/output voltage compatibility across JEDEC standards (JESD8-7/5/1A), and TSSOP48 package suitability for dense PCB layouts with live insertion support.

Technical Context

This device implements two independent 8-bit transparent latches, each with dedicated latch enable (LE) and output enable (OE) inputs-enabling selective control of data capture and bus release per section. Its CMOS architecture delivers ultra-low static power consumption while supporting mixed-voltage interfacing via 3.6 V tolerant I/Os.

The Dynamic Controlled Output (DCO) circuit dynamically adjusts output impedance during signal transitions to suppress ringing and ground bounce without degrading edge speed. Low-inductance multiple VCC/GND pins further minimize noise, and internal power-up/down high-impedance protection requires OE tied to VCC via pull-up for live insertion compliance.

FAQ

What is the minimum supply voltage for guaranteed operation of the 74AVC16373DGG,512?

The device is fully specified down to 1.2 V supply voltage per JEDEC JESD8-7, with functional operation confirmed at −40 °C to +85 °C ambient. Static parameters including VIH/VIL thresholds, propagation delay, and output drive strength are characterized and guaranteed across this full 1.2–3.6 V range-not just at nominal voltages.

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

DCO dynamically lowers output impedance during signal transitions to dampen reflections and reduce ringing, then restores full drive strength after settling-achieving ≤100 mV overshoot at 100 MHz without increasing rise/fall times. This eliminates need for external series termination resistors in many high-speed bus designs.

Can the 74AVC16373DGG,512 be used in hot-swap applications?

Yes-its internal power-up/power-down high-impedance state combined with OE pin requiring external VCC pull-up satisfies live insertion requirements. When OE is held HIGH during insertion, outputs remain in high-Z until system firmware asserts LE/OE, preventing bus contention and damage to upstream drivers.

What is the maximum clock/data toggle rate supported by this latch?

While not a clocked register, its 0.7 ns minimum propagation delay at 3.3 V enables reliable use in systems with effective bus toggle rates up to ~1 GHz, assuming proper PCB layout, load capacitance ≤30 pF, and supply decoupling. Maximum sustained data rate depends on system-level timing margins, not internal clock frequency.
