Product details
Overview
74AVC16245DGG,118 from Nexperia is a 16-bit non-inverting 3-state bus transceiver with dual direction control (1DIR/2DIR) and dual output enable (1OE/2OE), operating from 1.2 V to 3.6 V supply. It supports bidirectional data flow between two 8-bit buses or one unified 16-bit bus, features Dynamic Controlled Output (DCO) for noise reduction, and delivers sub-1.1 ns propagation delay at 3.3 V in high-speed digital interconnects.
For engineers reviewing the 74AVC16245DGG,118 datasheet, 74AVC16245DGG,118 pinout, 74AVC16245DGG,118 application, or 74AVC16245DGG,118 equivalent, key selection criteria include voltage-tolerant I/O (up to 3.6 V), live-insertion support via OE pull-up, low ground bounce from multiple VCC/GND pins, and JEDEC-compliant operation across 1.2–3.6 V rails.
Technical Context
This transceiver implements independent send/receive control per 8-bit segment using dedicated nDIR inputs and isolates buses via active-low nOE signals-enabling cascaded multi-chip bus architectures without contention. Its CMOS design ensures rail-to-rail input tolerance and ultra-low static current (≤40 µA at 3.6 V).
The integrated Dynamic Controlled Output (DCO) circuit dynamically adjusts output impedance during signal transitions to suppress simultaneous switching noise while preserving propagation speed. The TSSOP48 package includes eight GND and four VCC pins to minimize inductance and stabilize power delivery under fast switching loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.2 V to 3.6 V - enables interoperability across mixed-voltage systems (1.2 V core, 1.8 V I/O, 3.3 V legacy peripherals) |
| Propagation Delay | 0.5 ns (min) to 1.7 ns (max) at 3.0–3.6 V - supports >500 MHz bus toggle rates in high-speed interconnects |
| I/O Voltage Tolerance | Up to 3.6 V - allows safe interfacing with higher-voltage logic without level shifters |
| Output Enable Time | 0.7 ns (typ) to 3.7 ns (max) at 3.0–3.6 V - ensures rapid bus arbitration and low-latency state transitions |
| Power Dissipation Capacitance | 42 pF (enabled), 2 pF (disabled) - reduces dynamic power by >95% in 3-state standby mode |
| Operating Temperature | −40 °C to +85 °C - qualified for industrial-grade embedded and computing applications |
| Input Leakage Current | ≤2.5 µA max - minimizes standby current draw in battery-sensitive or always-on subsystems |
Pinout & Package
TSSOP48 plastic thin shrink small outline package (SOT362-1), 48-pin, body width 6.1 mm, with 8 GND and 4 VCC pins for low-noise power integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction control input (active HIGH) | Determines data flow direction per 8-bit segment: HIGH = A→B, LOW = B→A |
| 1OE, 2OE | Output enable input (active LOW) | Drives corresponding 8-bit port into high-impedance when HIGH; enables live insertion with pull-up |
| 1A0–1A7, 2A0–2A7 | Data I/O port A (side A) | First and second 8-bit bus interface; tolerant to 3.6 V regardless of VCC |
| 1B0–1B7, 2B0–2B7 | Data I/O port B (side B) | Complementary 8-bit bus interface; electrically identical to port A |
| VCC (pins 7, 18, 31, 42) | Supply voltage | Four distributed VCC pins reduce IR drop and improve transient response during switching |
| GND (pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight GND pins minimize ground bounce and ensure stable reference for all 32 I/Os |
Key Features
| Feature | Design Value |
|---|---|
| Dynamic Controlled Output (DCO) | Real-time output impedance adjustment during edge transitions suppresses SSN without sacrificing speed |
| Live Insertion Support | High-impedance default on power-up/down when nOE tied to VCC via pull-up resistor |

| Low Inductance Layout | Multiple VCC/GND pins placed adjacent to I/O banks minimize loop inductance and EMI generation |
| Rail-to-Rail Input Tolerance | Inputs accept −0.5 V to VCC + 0.5 V - eliminates need for external clamping diodes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit bus transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AVC16245DGGR | Same logic, identical pinout, but TI package (TSSOP48, SOT362-1 equivalent); slightly higher ICC max (100 µA vs 40 µA) | Valid for TI-based designs requiring same footprint; less suitable for ultra-low-power systems | Select if sourcing from TI distribution channels or aligning with existing TI BOMs |
| 74LVC16245APAG | NXP LVC variant: narrower VCC range (1.65–3.6 V); no DCO; higher tpd (2.4 ns min at 3.3 V) | Lacks live insertion support and noise suppression; acceptable only where cost outweighs performance | Choose only for legacy LVC compatibility or cost-sensitive non-critical interfaces |
Compared with SN74AVC16245DGGR, the 74AVC16245DGG,118 offers lower static power and tighter propagation delay specs; versus 74LVC16245APAG, it adds DCO, wider voltage range, and live-insertion capability-making it superior for high-speed, mixed-voltage, or hot-plug systems.

FAQ
What is the minimum supply voltage required for guaranteed operation?
The 74AVC16245DGG,118 is fully specified down to 1.2 V per JEDEC JESD8-7, with functional operation confirmed at 1.2 V supply, including VIH/VIL thresholds, propagation delay, and 3-state isolation-all validated across −40 °C to +85 °C ambient.
How does Dynamic Controlled Output (DCO) improve system-level noise performance?
DCO dynamically lowers output impedance during signal transitions to damp ringing and overshoot, reducing simultaneous switching noise (SSN) by up to 40% compared to fixed-drive transceivers-without increasing propagation delay or requiring external termination resistors.
Can this device be used for hot-swap applications, and what design precautions are needed?
Yes-tie 1OE and 2OE to VCC via ≥10 kΩ pull-up resistors to ensure high-impedance state during power-up/down. This prevents bus contention during insertion/removal. The device's 3.6 V I/O tolerance also protects against voltage transients during mating.
What is the maximum capacitive load each I/O can drive while maintaining timing specifications?
Per Nexperia's test conditions in Table 9, the device maintains full timing compliance driving up to 30 pF load capacitance (including PCB trace and probe effects) at VCC ≥ 2.3 V, with verified tpd ≤ 1.7 ns and tdis ≤ 3.7 ns under those conditions.
