Nexperia USA Inc. 74ALVC16836ADGG:11

Overview

74ALVC16836ADGG:11 from Nexperia is a 20-bit registered bus driver with inverted latch enable (active LOW), 3-state outputs, and edge-triggered clock input (LOW-to-HIGH). It operates across 1.2 V to 3.6 V supply, delivers ±24 mA output drive at 3.0 V, and supports high-speed data latching in industrial control backplanes and memory interface buffers.

For engineers reviewing the 74ALVC16836ADGG:11 datasheet, 74ALVC16836ADGG:11 pinout, 74ALVC16836ADGG:11 application, or 74ALVC16836ADGG:11 equivalent, key selection criteria include its multibyte flow-through pinout, JEDEC-compliant voltage thresholds (VIH/VIL), propagation delay ≤4.2 ns at 3.3 V, and TSSOP56 package thermal derating above 55 °C.

Technical Context

This device implements a synchronous 20-bit register with independent latch enable (LE) and clock (CP) control: when LE is LOW, A→Y path is transparent; when LE is HIGH, data is captured on CP's rising edge. OE operates independently to place outputs in high-impedance state without affecting internal latch state.

It features dual-voltage compliance (JESD8-5 for 2.3–2.7 V; JESD8B/JESD36 for 2.7–3.6 V), ESD robustness (HBM >2000 V, CDM >1000 V), and low-inductance multiple VCC/GND pins to suppress ground bounce in dense PCB layouts.

FAQ

What is the correct power-up sequencing for 74ALVC16836ADGG:11 to avoid bus contention?

OE must be held HIGH (via pull-up resistor to VCC) until VCC stabilizes and control logic is ready. This ensures all Y outputs remain in high-impedance state during power ramp. The minimum pull-up resistance is determined by the driver's sink current capability-typically ≤10 kΩ for standard CMOS drivers. Do not tie OE directly to GND or leave floating.

Can 74ALVC16836ADGG:11 operate reliably at 1.2 V supply?

Yes. The device is fully specified from 1.2 V to 3.6 V per JEDEC JESD8-1A. At 1.2 V, VIH is guaranteed ≥0.66 V and VIL ≤0.36 V; propagation delay increases to ≤12 ns (typical), and output drive reduces to ±8 mA. All DC and AC parameters in Tables 5–7 are validated across this full range.

How does the inverted latch enable (LE) affect timing setup relative to the clock (CP)?

When LE is LOW, the A→Y path is transparent-data appears at Y after tpd (≤4.2 ns at 3.3 V). When LE transitions HIGH, the device enters latch mode: subsequent data changes on A are ignored until CP's rising edge captures the present A value. Setup time (tsu = 1.5 ns min) is measured from An to CP, not LE.

Is thermal derating required for continuous operation at 85 °C ambient?

Yes. Total power dissipation must be derated linearly at 8 mW/K above 55 °C. At 85 °C, maximum allowed Ptot = 600 mW − (30 K × 8 mW/K) = 360 mW. This corresponds to ~15 switching outputs at 3.3 V with 50 pF load and 10 MHz toggle rate, assuming CPD = 22 pF per buffer in clocked mode.
