Nexperia USA Inc. 74AVC16836ADGG,118

Overview

74AVC16836ADGG,118 from Nexperia is a 20-bit registered bus driver with inverted latch enable, dynamic controlled outputs (DCO), and 3-state outputs. It operates across 1.2 V to 3.6 V supply, delivers sub-3 ns propagation delay at 3.3 V, supports live insertion via power-off output disable, and integrates DCO circuitry for noise-suppressed line driving in high-speed memory and data bus applications.

For engineers reviewing the 74AVC16836ADGG,118 datasheet, 74AVC16836ADGG,118 pinout, 74AVC16836ADGG,118 application, or 74AVC16836ADGG,118 equivalent, key selection considerations include its inverted register enable logic, TSSOP56 package pin mapping, DCO-enabled transient noise control, and JEDEC-compliant voltage scaling across 1.2–3.6 V operation.

Technical Context

This device implements a synchronous 20-bit register with separate clock (CP) and active-low latch enable (LE) inputs, enabling both edge-triggered and level-sensitive data capture modes. Its Dynamic Controlled Output (DCO) circuit dynamically modulates output impedance during signal transitions-initially lowering it for strong drive strength, then raising it to suppress ringing and ground bounce.

The architecture includes 20 independent A→Y data paths, dual active-low control inputs (OE and LE), and a dedicated CP input. All I/Os are 3.6 V tolerant regardless of VCC, and multiple distributed VCC/GND pins minimize inductance and ensure stable switching performance up to 500 MHz at 3.3 V.

FAQ

What is the purpose of the inverted latch enable (LE) input?

The LE input is active LOW, meaning data on A1–A20 is latched into the internal register on the rising edge of CP only when LE is held LOW. This inversion simplifies timing in synchronous systems where latch activation aligns with a deasserted control signal, reducing setup time constraints and eliminating need for external inverters in many FPGA- or ASIC-driven designs.

How does Dynamic Controlled Output (DCO) reduce noise without slowing down edges?

DCO dynamically lowers output impedance during initial signal transition to deliver high current for fast edge rates, then rapidly increases impedance mid-transition to dampen reflections and ringing. This two-phase behavior preserves <3 ns propagation delay while cutting peak SSN by up to 40%, as verified in Fig. 5's VOL/VOH vs. IOL/IOH curves across 1.8 V, 2.5 V, and 3.3 V supplies.

Can 74AVC16836ADGG,118 be used in 1.2 V systems with 3.3 V peripherals?

Yes - all inputs and outputs are 3.6 V tolerant regardless of VCC level. When powered from 1.2 V, the device accepts 3.3 V logic-high inputs safely and drives 3.3 V-tolerant loads with valid VOH/VOL levels per Table 6, enabling direct interconnection with legacy 3.3 V peripherals without external level-shifting circuitry.

Why are there eight GND pins and four VCC pins in the TSSOP56 package?

The distributed 8×GND and 4×VCC pins minimize loop inductance and provide low-impedance return paths for all 20 I/Os and internal logic. This layout reduces ground bounce to <50 mV peak under full 20-bit switching, ensures uniform power delivery across the die, and meets stringent noise requirements for DDR and high-speed test equipment applications as validated in the dynamic characteristics section.
