Nexperia USA Inc. 74AVC16836ADGG,112

Overview

74AVC16836ADGG,112 from Nexperia is a 20-bit registered bus driver with inverted latch enable (LE), dynamic controlled outputs (DCO), and 3-state outputs. It operates from 1.2 V to 3.6 V, delivers propagation delays as low as 0.7 ns 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,112 datasheet, 74AVC16836ADGG,112 pinout, 74AVC16836ADGG,112 application, or 74AVC16836ADGG,112 equivalent, key selection criteria include supply voltage range (1.2–3.6 V), DCO-enabled transient noise control, TSSOP56 package pin compatibility, and support for 500 MHz clock operation at 3.3 V.

Technical Context

The device implements a synchronous 20-bit register with separate clock (CP) and inverted 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-lowering it initially for strong drive, then raising it to suppress ringing and ground bounce without sacrificing speed.

It features 8 dedicated ground pins and 4 VCC pins distributed across the TSSOP56 package to minimize inductance and stabilize power delivery. Input/output tolerance up to 3.6 V allows interfacing with mixed-voltage systems, while power-off high-impedance behavior enables hot-plug capability in backplane and modular systems.

FAQ

What is the minimum supply voltage for guaranteed operation of the 74AVC16836ADGG,112?

The device is fully specified down to 1.2 V per JEDEC JESD8-7, with propagation delay, drive strength, and logic thresholds validated across the entire 1.2–3.6 V range. At 1.2 V, tpd is ≤4.7 ns and VOH/VOL meet 0.65×VCC and 0.35×VCC thresholds respectively - enabling direct integration with ultra-low-power microcontrollers and sensors.

How does the Dynamic Controlled Output (DCO) circuit reduce noise without slowing signal edges?

The DCO circuit uses internal feedback to temporarily lower output impedance during the initial 20–30% of the signal transition, delivering peak current for fast edge initiation, then rapidly increases impedance to dampen ringing. This dual-phase behavior preserves rise/fall times (≤2.0 ns) while cutting overshoot by up to 60% compared to standard AVCH drivers - verified in Fig. 5's VOL/VOH vs. IOL/IOH curves.

Can the 74AVC16836ADGG,112 be used in hot-swap applications without external circuitry?

Yes - its power-off high-impedance feature ensures all outputs go to high-Z when VCC drops below ~0.5 V, eliminating bus contention during insertion. OE should be pulled up to VCC via a 10 kΩ resistor to guarantee safe startup, and no external FETs or sequencing logic are required - confirmed in Section 1 and Table 4 limiting values.

What is the maximum clock frequency supported when using the latch enable (LE) input instead of the clock (CP) input?

When operating in transparent latch mode (LE = LOW), the maximum data rate is governed by the An→Yn propagation delay: 0.7 ns min at 3.3 V → 1.4 GHz theoretical toggle rate. However, functional limits are set by setup/hold timing relative to LE transitions; per Table 7, tW (LE pulse width) is 1.0 ns min at 3.3 V, supporting sustained 500 MHz latch-enable toggling - matching the CP-driven fmax specification.
