Product details
Overview
74LVCH16244ADGVJ from Nexperia is a 16-bit 3-state buffer/line driver with 5 V tolerant inputs and outputs, bus hold on all data inputs, IOFF partial power-down protection, and Schmitt-trigger inputs for noise immunity. 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 I/O expansion and memory address buffering applications.
For engineers reviewing the 74LVCH16244ADGVJ datasheet, 74LVCH16244ADGVJ pinout, 74LVCH16244ADGVJ application, or 74LVCH16244ADGVJ equivalent, this device is selected for high-density bidirectional bus buffering where input noise rejection, power-down safety, and 5 V logic compatibility are required in compact TVSOP48 packaging.
Technical Context
The device implements four independent 4-bit buffer sections, each controlled by its own active-low output enable (1OE–4OE), enabling granular bus segment control. Each section features Schmitt-trigger inputs for robust handling of slow-rising signals and bus hold circuitry on all 16 data inputs-eliminating external pull-ups.
IOFF circuitry actively disables outputs when VCC = 0 V, blocking backflow current during partial power-down. The 48-pin TVSOP package (SOT480-1) provides low-inductance multiple VCC and GND pins to minimize ground bounce and switching noise in high-speed digital interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 1.2 V to 3.6 V - enables operation across battery-powered, low-power, and standard 3.3 V logic domains |
| Input/output tolerance | 5 V - allows direct connection to legacy 5 V peripherals without level shifters |
| Propagation delay (VCC = 3.3 V) | 2.2 ns typical - supports >200 MHz bus timing in high-speed address/data latching |
| Bus hold current (VI = 0.8 V) | 75 μA at VCC = 3.0 V - maintains stable logic state on unconnected inputs without external resistors |
| IOFF leakage (VCC = 0 V) | ±10 μA max - prevents damaging back-current during hot-swap or partial system power-down |
| ESD rating (HBM) | >2000 V - meets JEDEC JS-001 Class 2 for robust handling in manufacturing and field environments |
| Operating temperature | −40 °C to +125 °C - qualified for extended industrial and under-hood embedded control applications |
Pinout & Package
74LVCH16244ADGVJ uses the SOT480-1 (TVSOP48) package: 48-pin plastic thin shrink small outline, 4.4 mm body width, 0.4 mm lead pitch, and exposed thermal pad not connected internally.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A0–1A3, 2A0–2A3, 3A0–3A3, 4A0–4A3 (pins 26–47) | Data inputs (16 total) | All feature bus hold - eliminates need for external pull-up/pull-down on unused or floating lines |
| 1Y0–1Y3, 2Y0–2Y3, 3Y0–3Y3, 4Y0–4Y3 (pins 1–23 odd/even) | 3-state buffered outputs (16 total) | High-impedance OFF-state activated by corresponding OE; compatible with shared bus topologies |
| 1OE, 2OE, 3OE, 4OE (pins 1, 24, 25, 48) | Active-low output enables | Independent control per 4-bit group - enables selective bus segmentation and power gating |
| VCC (pins 7, 18, 31, 42) | Supply voltage | Four dedicated VCC pins reduce IR drop and improve noise immunity in high-switching scenarios |
| GND (pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight GND pins provide low-inductance return paths - critical for signal integrity at >100 MHz edge rates |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Enables reliable operation with slow-rising signals (e.g., mechanical switches, long traces) without external hysteresis components |
| IOFF partial power-down | Prevents destructive back-current flow when VCC is off but I/O pins remain biased - essential for hot-plug and multi-rail systems |
| 5 V tolerant I/O | Allows seamless integration into mixed-voltage designs without discrete level translators - reduces BOM count and layout complexity |
| Bus hold on all data inputs | Eliminates 16 external pull-up resistors - saves PCB area, reduces assembly cost, and improves reliability in high-density layouts |
| Low dynamic power dissipation | CPD = 11.4 pF at VCC = 3.3 V - minimizes switching power in battery-operated and thermally constrained applications |
Applications
| Industrial PLC I/O Expansion | Memory Address Buffering |
|---|---|
|
Use Scenario: Isolating and driving 16-bit address/data buses between microcontroller and parallel SRAM or FPGA configuration memory. IC Role / Device Role / Timing Role: Bidirectional 3-state buffer with independent OE control per byte - enables time-multiplexed bus sharing and contention-free read/write cycles. Use Value: Propagation delay ≤4.1 ns at 3.3 V ensures setup/hold timing margins for 100+ MHz memory access; 5 V tolerance accommodates legacy memory ICs. |
Use Scenario: Driving high-capacitance address lines across backplane or multi-layer PCB in industrial controllers. IC Role / Device Role / Timing Role: Unidirectional line driver with Schmitt-trigger inputs - cleans up noisy or slow-rising address signals before reaching memory decoders. Use Value: Input hysteresis ≥0.35×VCC rejects noise spikes; 8-GND-pin layout suppresses ground bounce that could corrupt address decoding. |
| Automotive Body Control Module | Test Equipment Digital I/O Interface |
|
Use Scenario: Interfacing MCU GPIOs to 5 V sensor actuators (e.g., relays, solenoids) in under-hood ECUs. IC Role / Device Role / Timing Role: Voltage-level translating buffer with IOFF - safely isolates MCU during sleep mode while sensors remain powered. Use Value: −40 °C to +125 °C rating matches automotive under-hood requirements; IOFF leakage ≤20 μA prevents battery drain during extended shutdown. |
Use Scenario: Providing configurable 16-bit digital stimulus and capture channels in automated test equipment (ATE) fixtures. IC Role / Device Role / Timing Role: Programmable 3-state I/O buffer with per-group OE - enables flexible pin direction assignment and bus contention management.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC16244ADGV | No bus hold circuit; identical pinout, supply range, and 5 V tolerance | Requires external pull-up resistors on unused inputs - increases BOM and board space | Select when bus hold is unnecessary and cost minimization is prioritized over design simplicity |
| SN74ALVCH16244DGGR | Texas Instruments part; same function, 1.65–3.6 V range, no bus hold, higher drive strength (±24 mA vs ±24 mA) | Higher ICC (max 80 μA vs 20 μA) and no IOFF - unsuitable for partial power-down use cases | Select only if TI supply chain preference exists and IOFF/bus hold are not required in target system |
Compared with 74LVC16244ADGV, the 74LVCH16244ADGVJ adds bus hold and retains IOFF - reducing external components and improving power-down safety. Versus SN74ALVCH16244DGGR, it offers superior low-power operation and guaranteed back-current blocking, making it preferred for energy-sensitive and hot-swap designs.

FAQ
Does 74LVCH16244ADGVJ support hot-swap operation?
Yes - its IOFF circuitry actively disables outputs and limits back-current to ±20 μA when VCC = 0 V, enabling safe insertion/removal in live backplanes or multi-rail systems without disrupting other powered components.
Can unused inputs be left floating?
Yes - all 16 data inputs include integrated bus hold circuitry, which maintains a valid logic state without external resistors. Control inputs (OE pins) must still be actively driven HIGH or LOW per functional requirements.
What is the maximum capacitive load this buffer can drive reliably?
At VCC = 3.3 V and IO = ±24 mA, the output can drive up to 50 pF load capacitance while maintaining specified VOL/VOH levels and propagation delay - verified per JEDEC test conditions in Figure 6 and Table 9.
How does Schmitt-trigger input action improve noise immunity?
Schmitt-trigger inputs provide hysteresis (typically ≥0.35×VCC), meaning the threshold for rising-edge detection differs from falling-edge detection - rejecting short-duration noise spikes and ensuring clean transitions even with slow or noisy input waveforms.
