Nexperia USA Inc. 74ALVC16244DGG,112

Overview

74ALVC16244DGG,112 from Nexperia is a 16-bit CMOS buffer/line driver with 3-state outputs, configured as four independent 4-bit sections each controlled by dedicated active-low output enables (1OE–4OE). It operates across 1.2 V to 3.6 V supply, supports 5.5 V-tolerant inputs, and features IOFF partial power-down protection. Used in bus interface isolation and level translation between 2.5 V/3.3 V logic domains in industrial control backplanes.

For engineers reviewing the 74ALVC16244DGG,112 datasheet, 74ALVC16244DGG,112 pinout, 74ALVC16244DGG,112 application, or 74ALVC16244DGG,112 equivalent, key selection criteria include its quad-section enable architecture, ±24 mA drive at 3.0 V, TSSOP48 package thermal profile, and bus hold absence (distinguishing it from 74ALVCH16244 variants).

Technical Context

This device implements a flow-through pinout architecture optimized for minimal signal skew across all 16 channels, with separate VCC/GND pairs per functional quadrant to suppress ground bounce. Its IOFF circuitry actively disables outputs during power-down, blocking reverse current flow when VCC = 0 V while inputs remain biased.

Each of the four 4-bit sections operates independently: asserting 1OE places Y0–Y3 in high-impedance state regardless of A0–A3 logic levels; propagation delay is 1.0–3.0 ns (VCC = 3.0–3.6 V, CL = 50 pF), and disable time is 1.0–4.1 ns under identical conditions.

FAQ

Does 74ALVC16244DGG,112 support hot-swap insertion in live backplanes?

Yes - its IOFF circuitry guarantees output disable and reverse-current blocking when VCC = 0 V, enabling safe insertion into powered backplanes. The device draws <50 μA during power-down, preventing disruption to adjacent modules. This behavior is validated per JESD78 Class II latch-up testing.

Can this buffer drive 50 Ω transmission lines at 3.3 V without external termination?

Yes - it delivers ±24 mA output current at VCC = 3.0 V, sufficient to source/sink full current into 50 Ω loads at 85 °C. Measured propagation delay remains 1.0–3.0 ns under 50 pF load, confirming signal integrity up to 300 MHz with matched impedance routing.

How does the quad-output-enable architecture improve system-level timing control?

Each OE pin controls four dedicated outputs, allowing independent gating of bus segments (e.g., address vs. data lanes). This reduces enable/disable skew to <0.5 ns between sections and eliminates contention during partial bus arbitration - critical in multi-master industrial protocols like CANopen or Profibus.

Is bus hold functionality present on 74ALVC16244DGG,112?

No - bus hold is exclusive to the 74ALVCH16244 variant. This part requires external pull-up/pull-down resistors on unused inputs to prevent floating states. The absence reduces static current consumption by ~150 μA per input compared to bus-hold versions, beneficial in battery-powered monitoring nodes.
