Product details

Overview

74LVC16244ADGG,112 from Nexperia is a 16-bit non-inverting 3-state buffer/line driver in TSSOP48 package, operating from 1.2 V to 3.6 V supply, with 5 V tolerant inputs/outputs, Schmitt-trigger inputs for noise immunity, and IOFF partial power-down protection. It supports mixed-voltage interfacing between 3.3 V and 5 V logic domains in bus buffering applications.

For engineers reviewing the 74LVC16244ADGG,112 datasheet, 74LVC16244ADGG,112 pinout, 74LVC16244ADGG,112 application, or 74LVC16244ADGG,112 equivalent, key selection criteria include its 16-bit flow-through pinout, four independent 3-state enables (1OE–4OE), bus hold capability (on 74LVCH variant only), -40 °C to +125 °C temperature range, and compliance with JEDEC JESD8-7A/5A/C standards.

Technical Context

This device implements four independent 4-bit buffer sections, each controlled by a dedicated active-low output enable (1OE–4OE). Each section passes data from A-inputs to Y-outputs when enabled, entering high-impedance state otherwise - enabling bidirectional bus sharing without external logic.

Its IOFF circuitry disables outputs and blocks backflow current when VCC = 0 V, supporting hot-insertion and partial power-down systems. Schmitt-trigger inputs ensure robust operation with slow-rising signals, while 5 V tolerance allows direct connection to legacy TTL or 5 V microcontrollers without level-shifting components.

Use Scenario: Expanding GPIO count for door lock actuators, window lift motors, and mirror controls in BCM designs.

IC Role / Device Role / Timing Role: Level-translating buffer interfaces 3.3 V MCU GPIOs with 5 V automotive load drivers and sensor feedback lines.

Use Value: Schmitt-trigger inputs reject EMI from motor commutation; -40 °C to +125 °C rating ensures reliability under hood conditions.

Test Equipment Digital Pattern Generator

Medical Diagnostic Imaging Data Bus

Use Scenario: Driving high-fanout digital stimulus patterns to DUTs in automated test equipment with mixed-voltage fixtures.

IC Role / Device Role / Timing Role: 16-bit line driver provides precise timing-aligned outputs with sub-3 ns propagation delay for deterministic pattern generation.

Use Value: Flow-through pinout simplifies impedance-controlled trace routing; 11.4 pF CPD enables accurate power modeling at 100+ MHz clock rates.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 16-bit buffer/line driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
74LVCH16244ADGG	Includes bus hold on all data inputs; identical pinout, timing, and voltage specs	Eliminates need for external pull-ups on unused inputs in floating-bus scenarios	Select when input termination is impractical and bus hold functionality is required
SN74LVC16244ADGGR	Texas Instruments variant; same 1.2–3.6 V range, 5 V tolerant, but higher typical ICC (80 μA vs. 20 μA)	Compatible in footprint and function but exhibits higher static power in always-on monitoring circuits	Prefer for TI-design ecosystems where cross-supplier qualification is already established

Compared with 74LVCH16244ADGG, the 74LVC16244ADGG lacks bus hold but offers lower quiescent current; versus SN74LVC16244ADGGR, it delivers tighter ICC spec and broader JEDEC compliance coverage, making it optimal for low-power industrial control where input termination is managed externally.

FAQ

Is the 74LVC16244ADGG,112 pin-compatible with the 74LVCH16244ADGG?

Yes - both share identical TSSOP48 (SOT362-1) pinout, electrical specifications, and functional behavior. The sole difference is that the 74LVCH16244ADGG includes bus hold circuitry on all data inputs, while the 74LVC16244ADGG does not. No PCB redesign is needed for substitution if bus hold is not required.

Can this device drive 50 Ω transmission lines directly?

No - the 74LVC16244ADGG,112 is not designed as a line driver for controlled-impedance transmission lines. Its output structure supports capacitive loads up to 50 pF and resistive loads down to 500 Ω, but it lacks the current drive strength and edge-rate control required for clean 50 Ω signaling. Use dedicated line drivers or series termination for such applications.

What is the maximum output current per pin at 3.3 V supply?

At VCC = 3.3 V, the device delivers ±24 mA per output pin under DC conditions, as specified in Table 6 (VOH/VOL). This is validated across -40 °C to +125 °C ambient and accounts for worst-case voltage drop. Sustained operation at full drive requires thermal derating per the 500 mW total power dissipation limit.

Does this part support hot-plug operation in powered-backplane systems?

Yes - the integrated IOFF circuit actively disables outputs and blocks reverse current flow when VCC = 0 V, enabling safe insertion into live backplanes. This feature complies with JEDEC JESD78 requirements for partial power-down interoperability and has been verified at ±10 μA leakage under 5.5 V applied to I/O pins during power-off.
