Product details
Overview
74LVC16240ADGG,118 from Nexperia is a 16-bit inverting buffer/line driver with 3-state outputs, 5 V tolerant I/O, and four independent output-enable inputs (1OE–4OE). It operates from 1.2 V to 3.6 V supply, supports mixed-voltage interfacing (3.3 V logic driving 5 V buses), and features IOFF partial power-down protection. It is used in address/data bus buffering for industrial controllers and FPGA I/O expansion.
For engineers reviewing the 74LVC16240ADGG,118 datasheet, 74LVC16240ADGG,118 pinout, 74LVC16240ADGG,118 application, or 74LVC16240ADGG,118 equivalent, this page delivers verified electrical specs, TSSOP48 pin mapping, real-world use cases, and validated alternatives - all grounded in Nexperia's Rev. 7 (2024) product data sheet.
Technical Context
The device implements four independent 4-bit inverting buffers, each controlled by its own active-low output enable (1OE–4OE). Each buffer section drives four inverted outputs (e.g., 1Y0–1Y3 from 1A0–1A3), with high-impedance OFF-state when OE is HIGH. The IOFF circuit disables outputs during power-down, blocking backflow current even when up to 5.5 V is applied to outputs.
All inputs and outputs tolerate 0 V to 5.5 V regardless of VCC (1.2 V–3.6 V), enabling direct interface between 3.3 V logic and legacy 5 V systems. Propagation delay is as low as 2.3 ns (typ.) at VCC = 3.0 V–3.6 V, and output skew is guaranteed ≤1.0 ns across same-package outputs switching in the same direction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 1.2 V to 3.6 V - enables operation in ultra-low-power microcontroller domains and standard 3.3 V systems. |
| I/O voltage tolerance | 0 V to 5.5 V - allows safe connection to 5 V buses without level shifters in mixed-voltage designs. |
| Propagation delay | 2.3 ns (typ.) at VCC = 3.3 V - supports >200 MHz bus timing margins for address/data latching. |
| IOFF leakage | ≤10 μA at VCC = 0 V, VI/VO = 5.5 V - prevents damaging back-current during hot-swap or partial power-down. |
| Output drive strength | ±24 mA at VCC = 3.0 V - sufficient to drive 15 pF loads over 10 cm PCB traces with clean edges. |
| Operating temperature | −40 °C to +125 °C - qualified for under-hood automotive ECUs and industrial motor drives. |
| ESD rating | HBM >2000 V, CDM >1000 V - meets IEC 61000-4-2 Level 3 robustness for board-level handling. |
Pinout & Package
TSSOP48 package (SOT362-1): plastic thin shrink small outline, 48 leads, 6.1 mm body width, 0.5 mm pitch, exposed pad not present. Pin 1 index marked by notch; pins numbered counterclockwise.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 48, 25, 24 | 1OE, 2OE, 3OE, 4OE | Active-low output enable for respective 4-bit buffer groups - HIGH forces associated Y outputs into high-Z. |
| 2–3, 5–6, 8–9, 11–12, 13–14, 16–17, 19–20, 22–23 | 1Y0–1Y3, 2Y0–2Y3, 3Y0–3Y3, 4Y0–4Y3 | Inverted buffered outputs - logic LOW input yields HIGH output and vice versa. |
| 47–46, 44–43, 41–40, 38–37, 36–35, 33–32, 30–29, 27–26 | 1A0–1A3, 2A0–2A3, 3A0–3A3, 4A0–4A3 | Buffer input terminals - accept 3.3 V or 5 V signals regardless of VCC setting. |
| 4, 10, 15, 21, 28, 34, 39, 45 | GND | Eight dedicated ground pins - minimize ground bounce across 16-bit switching events. |
| 7, 18, 31, 42 | VCC | Four distributed supply pins - reduce IR drop and improve noise immunity on wide buses. |
Key Features
| Feature | Design Value |
|---|---|
| 5 V tolerant I/O | Enables direct interconnection with 5 V peripherals (e.g., legacy ADCs, EEPROMs) without external level translators. |
| MULTIBYTE flow-through pinout | Input/output pairs aligned on opposite sides (e.g., 1A0/1Y0 at pins 47/2) - simplifies layer routing and reduces crosstalk in dense PCB layouts. |
| IOFF partial power-down | Prevents current backflow when VCC = 0 V but bus lines remain at 5 V - critical for hot-pluggable modules and fail-safe shutdown. |
| Low dynamic power | CPD = 11.4 pF (VCC = 3.3 V) - limits switching power to <1.5 mW per bit at 10 MHz, easing thermal design in fanless enclosures. |
| JEDEC-compliant voltage ranges | Validated for JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), and JESD8-C/JESD36 (2.7–3.6 V) - ensures interoperability across LVTTL, LVCMOS, and sub-1.8 V logic families. |
Applications
| Industrial PLC Backplane Buffering | FPGA I/O Expansion Interface |
|---|---|
Use Scenario: Isolating and driving 16-bit parallel address/data bus between ARM-based controller and modular I/O cards in a DIN-rail mounted PLC. IC Role / Device Role / Timing Role: Inverting 3-state buffer providing level translation (3.3 V MCU ↔ 5 V fieldbus) and bus contention control via independent OE lines. Use Value: Eliminates need for discrete level shifters; IOFF prevents bus corruption during card hot-swap; 125 °C rating supports operation in uncooled control cabinets. |
Use Scenario: Extending FPGA GPIO count to drive multiple SPI peripherals (ADCs, DACs, sensors) requiring 5 V signaling while FPGA core runs at 1.2 V. IC Role / Device Role / Timing Role: Bidirectional bus buffer with 5 V tolerant outputs, enabling FPGA to safely source/sink 5 V logic levels without violating core voltage limits.

IC Role / Device Role / Timing Role: Precision 3-state buffer ensuring signal integrity across long backplane traces, with independent OE per channel for sequential activation. Use Value: Low output skew (<1.0 ns) maintains timing alignment across multi-channel triggers; 24 mA drive sustains logic levels into 50 Ω terminated lines. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit inverting buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC16240ADGGR | TSSOP48 package, identical electrical specs, same −40 °C to +125 °C rating, RoHS-compliant lead finish differs (Nexperia uses matte Sn, TI uses NiPdAu). | No functional difference - validated drop-in replacement in existing PCB footprints. | Select if sourcing from TI-authorized distributors is required for supply chain diversification. |
| 74ALVC16240PW,118 | Same pinout, but ALVC variant offers faster tpd (1.7 ns typ. at 3.3 V) and higher drive (±24 mA at 2.5 V), yet narrower VCC range (2.3 V–3.6 V) and no 1.2 V support. | Not suitable for ultra-low-voltage (1.2 V–1.8 V) MCU interfaces; better for high-speed 3.3 V-only systems. | Choose only when speed >2.3 ns is mandatory and supply is fixed at ≥2.3 V. |
Compared with SN74LVC16240ADGGR, the 74LVC16240ADGG,118 offers identical functionality with Nexperia-specific quality screening and longer production lifecycle commitment; versus 74ALVC16240PW,118, it trades 0.6 ns speed for broader voltage flexibility and lower static current - making it superior for battery-powered or multi-rail embedded systems.

FAQ
Can 74LVC16240ADGG,118 operate at 1.2 V supply while driving 5 V-tolerant loads?
Yes. The device is fully specified down to VCC = 1.2 V and maintains 5 V tolerance on all I/O pins across that entire supply range. Input thresholds scale with VCC (e.g., VIH = 0.65×VCC at 1.65 V), and output drive remains functional - though VOL rises slightly (0.12 V max at 1.2 V) due to reduced rail headroom.
What happens to outputs when VCC = 0 V and 5 V is applied to Y pins?
With VCC = 0 V, the IOFF circuit activates automatically, disabling all outputs and limiting OFF-state leakage to ≤10 μA (per pin) even with 5.5 V applied. This prevents reverse current flow into the powered-down IC, protecting both the buffer and upstream drivers.
Is the pinout compatible with older 74LVC16244 or 74LVC16245 devices?
No. While functionally similar, 74LVC16240A has a unique MULTIBYTE flow-through layout optimized for 4-group buffering (1A0–1A3/1Y0–1Y3 on opposing edges), unlike the clustered I/O arrangement of 16244 (non-inverting) or 16245 (non-inverting, bus transceiver). PCB redesign is required for substitution.
How does the 4-output-enable architecture improve system-level bus management?
Each OE (1OE–4OE) controls exactly four outputs, enabling granular bus partitioning - e.g., one OE can isolate memory address lines while another enables data lines during DMA transfers. This eliminates contention without requiring full bus arbitration logic, reducing gate count and latency in resource-constrained controllers.
