Product details
Overview
74LVCH16244ADGG,112 from Nexperia is a 16-bit CMOS buffer/line driver with 3-state outputs, four independent output-enable inputs (1OE–4OE), 5 V tolerant I/O, bus hold on all data inputs, and IOFF partial power-down protection. It operates from 1.2 V to 3.6 V supply and supports mixed-voltage interfacing between 3.3 V and 5 V systems in industrial control backplanes and memory expansion modules.
For engineers reviewing the 74LVCH16244ADGG,112 datasheet, 74LVCH16244ADGG,112 pinout, 74LVCH16244ADGG,112 application, or 74LVCH16244ADGG,112 equivalent, this device is selected for high-density bidirectional bus buffering where input voltage translation, bus hold stability, and low-noise 48-pin TSSOP packaging are critical design requirements.
Technical Context
This device implements four independent 4-bit non-inverting buffers, each controlled by a dedicated active-low output enable (1OE–4OE). All 16 inputs feature Schmitt-trigger action and bus hold circuitry-eliminating external pull-ups-and support 5 V tolerant operation regardless of VCC level (1.2 V–3.6 V).
The IOFF circuit ensures high-impedance outputs when VCC = 0 V, preventing backflow current during partial power-down. Propagation delay ranges from 1.0 ns (VCC = 2.7 V) to 5.5 ns (VCC = 3.6 V, –40 °C to +125 °C), with enable/disable times under 8.0 ns across full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.2 V to 3.6 V - enables direct interface with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains |
| I/O Voltage Tolerance | 5 V - allows safe connection to legacy 5 V buses without level shifters |
| Bus Hold Current | ±75 μA at VCC = 3.0 V - actively maintains logic state on unused inputs without external resistors |
| Propagation Delay (max) | 5.5 ns at VCC = 3.6 V, –40 °C to +125 °C - supports >100 MHz bus timing margins |
| IOFF Leakage | ±20 μA at VCC = 0 V, VI/VO = 5.5 V - prevents damaging backfeed during hot-swap or partial power-down |
| ESD Protection | HBM >2000 V, CDM >1000 V - meets industrial-grade robustness per JS-001/JS-002 |
| Operating Temperature | –40 °C to +125 °C - qualified for extended-temperature industrial and automotive-adjacent applications |

Key Features
| Feature | Design Value |
|---|---|
| Bus hold on all data inputs | Eliminates need for 16 external pull-up/pull-down resistors, reducing BOM count and PCB area |
| IOFF partial power-down | Enables safe insertion/removal in live backplanes by disabling outputs when VCC = 0 V |
| 5 V tolerant I/O at any VCC | Permits interoperability with legacy 5 V peripherals while powered from modern low-voltage rails |
| Schmitt-trigger inputs | Accepts slow-rising signals (e.g., from mechanical switches or long traces) without oscillation or metastability |
| Low-inductance multi-GND/VCC layout | Eight GND and four VCC pins suppress simultaneous switching noise in high-speed parallel bus applications |

FAQ
Does 74LVCH16244ADGG,112 support hot-swap operation?
Yes. Its IOFF circuitry forces all outputs into high-impedance state when VCC = 0 V, preventing back-current flow during live insertion or removal in backplane or modular systems. This is verified per JEDEC JESD78 and confirmed in Section 1 of the datasheet.
Can it interface between 1.8 V and 5 V logic without external level shifters?
Yes. All inputs and outputs are 5 V tolerant across the full 1.2 V–3.6 V VCC range. A 1.8 V-powered 74LVCH16244ADGG,112 accepts 0–5 V input signals and drives 5 V-tolerant loads directly-no external components needed for voltage translation.
What is the maximum clock/data rate supported?
While not a clocked device, its 5.5 ns max propagation delay (VCC = 3.6 V, –40 °C to +125 °C) supports reliable operation on parallel buses up to ~100 MHz (10 ns period), assuming proper trace termination and load capacitance ≤30 pF per line.
How does bus hold behave during power-up or brown-out?
Bus hold remains active down to VCC = 1.2 V and sustains input state even during slow-ramping or unstable supply conditions. It disables only when VI exceeds VCC (per datasheet note [2]), ensuring deterministic behavior during power sequencing.
