Product details
Overview
74LVC16244AEV,118 from Nexperia is a 16-bit non-inverting 3-state buffer/line driver with four independent output-enable inputs (1OE–4OE), 5 V tolerant I/O, and IOFF partial power-down protection. It operates from 1.2 V to 3.6 V supply, supports mixed-voltage translation between 3.3 V and 5 V logic domains, and features Schmitt-trigger inputs for noise immunity. Used in high-density bus interface applications such as memory address/data buffering in industrial control backplanes.
For engineers reviewing the 74LVC16244AEV,118 datasheet, 74LVC16244AEV,118 pinout, 74LVC16244AEV,118 application, or 74LVC16244AEV,118 equivalent, this device delivers deterministic 3-state timing, robust 5 V tolerance on all I/O pins, bus hold functionality (on 74LVCH variant), and JEDEC-compliant ESD performance - critical for reliable signal integrity in multi-rail embedded systems.
Technical Context
This device implements four independent 4-bit buffer sections, each controlled by its own active-low output enable (1OE–4OE). Each section passes data from A-inputs to Y-outputs when enabled, and presents high-impedance outputs when disabled - enabling bidirectional bus sharing without external isolation.
Its IOFF circuitry actively disables outputs and blocks current flow when VCC = 0 V, preventing backfeed during hot-insertion or partial power-down. Schmitt-trigger inputs ensure clean switching with slow-rising signals, while bus hold (on LVCH version) maintains valid logic states on unused inputs without external pull-ups.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 1.2 V to 3.6 V - enables direct operation from low-voltage rails (e.g., 1.8 V or 2.5 V) while maintaining full 5 V I/O tolerance. |
| I/O voltage tolerance | 0 V to 5.5 V - allows safe interfacing with legacy 5 V TTL/CMOS logic without level shifters. |
| Propagation delay (tpd) | 1.1 ns (min) to 4.1 ns (max) at VCC = 3.3 V - ensures sub-5 ns timing margin for high-speed parallel bus operation up to ~100 MHz. |
| IOFF leakage current | ±10 μA max at VCC = 0 V - guarantees safe hot-swap capability and prevents damaging back-current during system power sequencing. |
| Bus hold current (LVCH) | ±75 μA at VCC = 3.0 V - eliminates need for external pull-up/pull-down resistors on floating data inputs, reducing BOM count and board space. |
| ESD rating (HBM) | >2000 V - meets industrial-grade robustness requirements per ANSI/ESDA/JEDEC JS-001 Class 2. |
| Operating temperature | −40 °C to +125 °C - qualified for extended-temperature industrial and automotive under-hood environments. |
Pinout & Package
74LVC16244AEV,118 is packaged in SOT702-1 (HVQFN48), a 48-pin, 7 mm × 7 mm, 0.5 mm pitch, thermally enhanced quad flat no-lead package with exposed thermal pad. This package provides low-inductance power/ground paths and superior thermal dissipation versus TSSOP/TVSOP alternatives.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A0–1A3, 2A0–2A3, 3A0–3A3, 4A0–4A3 | Data input (16 total) | Four groups of 4-bit inputs; each group drives corresponding Y-output section when respective OE is asserted. |
| 1Y0–1Y3, 2Y0–2Y3, 3Y0–3Y3, 4Y0–4Y3 | Data output (16 total) | Corresponding non-inverting buffered outputs; enter high-impedance state when associated OE is HIGH. |
| 1OE, 2OE, 3OE, 4OE | Active-low output enable | Independent control per 4-bit section; LOW enables outputs, HIGH forces 3-state (Z) condition. |
| VCC (pins 7, 18, 31, 42) | Supply voltage | Four dedicated VCC pins minimize IR drop and supply noise across wide die area; supports decoupling at multiple locations. |
| GND (pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight GND pins provide low-inductance return paths, reducing ground bounce in high-speed switching applications. |
Key Features
| Feature | Design Value |
|---|---|
| 5 V tolerant I/O | Enables seamless interoperation with 5 V peripherals while powered from 1.8 V or 2.5 V rails - eliminating level translators in mixed-voltage systems. |
| IOFF partial power-down | Prevents destructive back-current flow when VCC is off, supporting live insertion/removal in modular backplane architectures. |
| Schmitt-trigger inputs | Provides hysteresis (typically 0.3–0.5 V) to reject noise and accommodate slow edge rates from mechanical switches or long traces. |
| Low dynamic power (CPD = 11.4 pF) | Reduces switching power consumption in high-frequency bus applications - critical for thermally constrained embedded designs. |
| JEDEC-compliant ESD protection | HBM >2000 V and CDM >1000 V meet industrial reliability standards without requiring external protection components. |

| Industrial PLC Backplane Interface | Automotive Body Control Module (BCM) |

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 |
|---|---|---|---|
| 74LVCH16244ADGV | Identical logic function and pinout; adds bus hold on all data inputs (74LVC16244AEV lacks bus hold). | Eliminates need for external pull-ups on unused inputs - advantageous in high-reliability, low-maintenance systems where floating nodes must be avoided. | Select when input stability without external components is required; otherwise, 74LVC16244AEV offers identical core functionality at lower cost. |
| SN74LVC16244ADGGR | Texas Instruments variant in same TSSOP48 package; compatible pinout but different thermal pad design and slightly higher tpd (max 5.5 ns vs 4.1 ns). | Valid for drop-in replacement in TI-centric designs; however, tighter timing specs of Nexperia part preferred for >25 MHz bus timing closure. | Choose for TI ecosystem alignment; prefer Nexperia 74LVC16244AEV,118 when optimizing for worst-case propagation delay or industrial temperature margin. |
Compared with 74LVCH16244ADGV, the 74LVC16244AEV,118 omits bus hold but retains identical timing, power, and 5 V tolerance - making it ideal for cost-sensitive, fully driven-bus applications. Against SN74LVC16244ADGGR, it delivers faster guaranteed propagation and broader temperature qualification, enhancing timing margin in thermally demanding deployments.

FAQ
Is 74LVC16244AEV,118 pin-compatible with 74LVCH16244ADGV?
Yes - both share identical pinout, package (SOT702-1), and functional behavior. The only difference is that 74LVCH16244ADGV includes bus hold on all data inputs, whereas 74LVC16244AEV,118 does not. No PCB redesign is needed for substitution, but unused inputs on the LVC version require external termination if left floating.
What is the maximum clock frequency supported for reliable 16-bit bus operation?
Based on worst-case propagation delay of 4.1 ns and minimum pulse width requirements, the device supports reliable operation up to 100 MHz for single-directional data transfer. For bidirectional time-multiplexed buses, derate to ≤25 MHz to maintain setup/hold margins across temperature and voltage extremes.
Does 74LVC16244AEV,118 support hot-plug operation?
Yes - its IOFF circuitry actively disables outputs and limits power-off leakage to ±10 μA when VCC = 0 V, preventing back-current flow into powered sections. This enables safe insertion/removal in live backplane or modular chassis systems without disrupting adjacent circuitry.
Can this device drive standard 50 Ω transmission lines directly?
No - it is rated for capacitive loads up to 50 pF and DC loads up to ±24 mA per output. Driving 50 Ω lines requires series termination or a dedicated line driver. However, it can reliably drive unterminated stubs ≤5 cm on FR-4 PCBs with proper impedance control and local decoupling.
