Product details
Overview
74AVCH16245DGG,112 from Nexperia is a 16-bit non-inverting 3-state bus transceiver with dual direction (nDIR) and dual output-enable (nOE) controls, designed for bidirectional data flow between voltage-level-shifted or isolated buses in low-voltage systems. It operates from 1.2 V to 3.6 V, supports 3.6 V-tolerant I/O, features bus-hold on all inputs, and delivers sub-2 ns propagation delay at 3.3 V. It is used in high-speed memory expansion interfaces and FPGA-to-ASIC interconnects where signal integrity and power efficiency are critical.
For engineers reviewing the 74AVCH16245DGG,112 datasheet, 74AVCH16245DGG,112 pinout, 74AVCH16245DGG,112 application, or 74AVCH16245DGG,112 equivalent, key selection considerations include its dynamic controlled output (DCO) circuitry for noise reduction without speed penalty, live insertion support via pull-up on nOE, and dual 8-bit partitioning capability for flexible bus segmentation.
Technical Context
The device implements two independent 8-bit transceiver blocks (A↔B), each with dedicated nDIR and nOE pins enabling cascaded multi-chip bus control. Its CMOS architecture uses dynamic impedance adjustment during switching transitions to suppress simultaneous switching noise while maintaining full-speed operation.
All 32 I/O pins feature active bus-hold circuitry that maintains valid logic states on floating inputs without external resistors, and low-inductance multiple VCC/GND pins minimize ground bounce in high-density PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 1.2 V to 3.6 V - enables interoperability across mixed-voltage domains (1.2 V core, 1.8 V I/O, 3.3 V legacy peripherals) |
| Propagation delay (VCC = 3.3 V) | 0.7–2.0 ns - ensures sub-nanosecond timing margins in DDR memory buffers and high-speed serial link sideband channels |
| I/O voltage tolerance | Up to 3.6 V - allows safe interfacing with higher-voltage peripherals while powered from lower supply rails |
| Bus-hold current (VCC = 3.0 V) | ±75 µA - actively sustains logic levels on unconnected or unterminated data lines without pull resistors |
| Dynamic Controlled Output (DCO) | Real-time output impedance modulation - reduces ringing and crosstalk on transmission lines without degrading edge rate |
| Power-off leakage (VCC = 0 V) | ±10 µA - prevents back-driving of powered-down subsystems during hot-swap operations |
| Enable/disable time (VCC = 3.3 V) | 2.3–3.9 ns - supports precise timing control in synchronous bus arbitration schemes |

| 2A0–2A7 (pins 26–36) | Data port A (bank 2) | Independent 8-bit port supporting dual-bank operation or 16-bit wide data path |
| 2B0–2B7 (pins 13–23) | Data port B (bank 2) | Complementary 8-bit port enabling full 16-bit transceiver mode or split 8-bit configuration |
| VCC (pins 7, 18, 31, 42) | Supply voltage | Four distributed power pins reduce IR drop and improve PSRR in high-frequency operation |
| GND (pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight ground pins minimize ground loop inductance and suppress simultaneous switching output (SSO) noise |
Key Features
| Feature | Design Value |
|---|---|
| Dynamic Controlled Output (DCO) | Adjusts output driver impedance in real time to dampen reflections on unterminated traces without slowing edges |
| Live Insertion support | High-impedance outputs maintained during power-up/down when nOE tied to VCC via pull-up resistor |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AVCH16245DGGR | Same functionality and pinout; Texas Instruments version with identical 1.2–3.6 V operation and bus-hold | No functional difference; TI part has separate JEDEC qualification and slightly different thermal resistance (RθJA = 52 °C/W vs Nexperia's 58 °C/W) | Select based on preferred supply chain or qualification documentation requirements |
| 74LVC16245APAG | Lower drive strength (24 mA vs 32 mA), no DCO circuitry, 1.65–3.6 V only, no bus-hold on all inputs | Suitable for cost-sensitive, lower-speed applications where noise suppression and live insertion are not required | Choose only if design operates strictly above 1.65 V and does not require DCO or bus-hold functionality |
Compared with SN74AVCH16245DGGR, the 74AVCH16245DGG,112 offers tighter thermal performance margin in compact TSSOP48 layouts; versus 74LVC16245APAG, it provides essential DCO and full-voltage-range bus-hold for robustness in mixed-supply industrial systems.

FAQ
What is the minimum supply voltage for guaranteed operation?
The 74AVCH16245DGG,112 is fully specified down to 1.2 V per JEDEC JESD8-7, with static and dynamic parameters validated across −40 °C to +85 °C at this rail. Propagation delay remains under 5.4 ns and bus-hold current exceeds 25 µA at 1.2 V, ensuring reliable operation in ultra-low-power battery-backed systems.
How does the Dynamic Controlled Output (DCO) circuit improve signal integrity?
The DCO circuit dynamically adjusts output driver impedance during signal transitions to match line characteristics, suppressing reflections and overshoot without reducing edge slew rate. This eliminates the need for external series termination resistors on PCB traces up to 15 cm in length, verified by Nexperia's Figure 4 and Figure 5 output voltage vs. current curves.
Can this device be used as two independent 8-bit transceivers?
Yes - the 74AVCH16245DGG,112 contains two functionally identical 8-bit sections (1A/1B and 2A/2B), each with dedicated nDIR and nOE pins. This allows independent direction control and bus isolation, enabling use cases such as separate address/data bus segmentation or dual peripheral interfacing without shared timing constraints.
What is the recommended pull-up resistor value for nOE during live insertion?
A 10 kΩ pull-up resistor to VCC is recommended for nOE pins to ensure high-impedance outputs during power-up/power-down sequences. This value balances fast release from reset against quiescent current draw (<1 µA at 3.3 V), and is validated in Nexperia's Application Note AN10771 for hot-swap compliance in backplane systems.
