Product details
Overview
74LVC16240ADGG,112 from Nexperia is a 16-bit inverting 3-state buffer/line driver in TSSOP48 package, featuring four independent output-enable inputs (1OE–4OE), 5 V tolerant I/O (up to 5.5 V on outputs when disabled), and operation from 1.2 V to 3.6 V supply. It supports mixed-voltage interfacing between 3.3 V and 5 V systems and includes IOFF circuitry for partial power-down protection. Used in address/data bus buffering for industrial controllers and FPGA I/O expansion.
For engineers reviewing the 74LVC16240ADGG,112 datasheet, 74LVC16240ADGG,112 pinout, 74LVC16240ADGG,112 application, or 74LVC16240ADGG,112 equivalent, key selection criteria include 5 V tolerance with 1.2 V–3.6 V VCC range, propagation delay ≤4.2 ns at 3.3 V, 3-state enable/disable timing (ten ≤5.0 ns, tdis ≤4.9 ns), and guaranteed -40 °C to +125 °C operation.
Technical Context
The device implements four independent 4-bit inverting buffers, each controlled by its own active-low output-enable input (1OE–4OE). Each buffer section drives four outputs (e.g., 1Y0–1Y3) from four corresponding inverted inputs (1A0–1A3).
IOFF circuitry ensures outputs enter high-impedance state and block backflow current when VCC = 0 V, enabling safe hot-insertion in multi-rail systems. Input and output clamping diodes support 5.5 V tolerance even during power-down, satisfying JEDEC JESD8-7A/5A/C and JESD36 compliance across voltage ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC 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 | Up to 5.5 V - Allows connection to 5 V buses without level shifters, even when device is unpowered. |

| ten / tdis (Max) | 5.0 ns / 4.9 ns at VCC = 3.3 V - Ensures tight timing control for synchronous bus gating. |
| IOFF Leakage | ±10 μA max at VI/VO = 5.5 V, VCC = 0 V - Prevents damaging back-current during partial power-down. |
| Operating Temp | -40 °C to +125 °C - Qualified for under-hood automotive modules and industrial motor drives. |

Key Features
| Feature | Design Value |
|---|---|
| 5 V tolerant I/O | Enables direct connection to legacy 5 V peripherals without external level translators in mixed-voltage systems. |
| MULTIBYTE flow-through pinout | Input/output pairs aligned on opposite sides of package - Simplifies PCB routing and reduces trace crosstalk in dense layouts. |
| IOFF partial power-down protection | Prevents reverse current flow when VCC is off but 5 V signals remain present on I/O pins - critical for hot-swap and power sequencing. |
| Low dynamic power (CPD = 11.4 pF) | Reduces switching power dissipation in high-frequency bus applications, supporting energy-efficient system design. |

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 | Same logic function and pinout; RoHS-compliant, green package; identical electrical specs and thermal performance. | No functional difference - suitable for drop-in replacement where TI sourcing is preferred or dual-sourcing required. | Select when TI's distribution network or long-term availability commitments are prioritized over Nexperia's lead times. |
| 74ALVC16240PW,118 | Higher speed (tpd ≤3.2 ns at 3.3 V), but narrower VCC range (2.3 V–3.6 V); no 1.2 V–1.95 V support. | Not suitable for ultra-low-voltage (1.2 V/1.8 V) FPGA I/O banks; better for 2.5 V/3.3 V-only systems needing faster timing. | Choose only if system operates strictly above 2.3 V and requires sub-3.5 ns propagation delay; verify IOFF and 5 V tolerance match. |
Compared with SN74LVC16240ADGGR, the 74LVC16240ADGG,112 offers identical functionality with Nexperia's extended temperature and qualification coverage; versus 74ALVC16240PW,118, it trades peak speed for broader voltage flexibility and guaranteed 1.2 V operation - critical for battery-powered or multi-supply SoC interfaces.

FAQ
What is the maximum allowable input voltage when VCC = 0 V?
When VCC = 0 V, the device's IOFF circuitry activates, allowing up to 5.5 V on any input or output pin without damage or back-current flow. This is verified per Absolute Maximum Ratings Table 4 and supported by HBM/CDM ESD ratings exceeding 2000 V and 1000 V respectively.
Can this device drive a 50 pF load at 100 MHz?
Yes - with CPD = 11.4 pF and tpd ≤4.2 ns at VCC = 3.3 V, the device supports 100 MHz operation into 50 pF loads. Dynamic power calculation (PD = CPD × VCC² × fi × N) confirms <15 mW typical dissipation under these conditions, well within the 500 mW Ptot limit.
How many independent 3-state control groups does it provide?
The device provides four independent 3-state control groups via dedicated active-low enables: 1OE controls outputs 1Y0–1Y3; 2OE controls 2Y0–2Y3; 3OE controls 3Y0–3Y3; 4OE controls 4Y0–4Y3. Each group operates autonomously, enabling segmented bus isolation.
Is the pinout compatible with older 74LVC16240 variants?
Yes - the 74LVC16240ADGG,112 uses the standard SOT362-1 (TSSOP48) pinout defined in Rev. 7 (March 2024), matching prior revisions and industry-standard 74LVC16240 footprints. Pin functions, numbering, and physical layout are identical to 74LVC16240ADGG,118 and 74LVC16240ADL variants.
