Nexperia USA Inc. 74AVC16T245DGG,112

Overview

74AVC16T245DGG,112 from Nexperia is a 16-bit dual-supply translating transceiver with bidirectional level translation, 3-state outputs, and independent VCC(A) and VCC(B) rails (0.8 V to 3.6 V). It supports two 8-bit or one 16-bit data path, features per-port direction (nDIR) and output enable (nOE), and implements IOFF for partial power-down. Used in voltage-domain bridging between 1.2 V SoCs and 3.3 V peripherals in industrial control backplanes.

For engineers reviewing the 74AVC16T245DGG,112 datasheet, 74AVC16T245DGG,112 pinout, 74AVC16T245DGG,112 application, or 74AVC16T245DGG,112 equivalent, key selection criteria include configurable dual-rail operation, suspend-mode behavior when either supply is at GND, JEDEC-compliant voltage translation across six logic families, and guaranteed timing up to 380 Mbit/s in ≥1.8 V → 3.3 V translation.

Technical Context

This device implements two independent 8-bit transceiver blocks (Port A and Port B), each with dedicated nDIR and nOE controls. Input circuitry on nAn/nDIR/nOE is referenced to VCC(A); nBn inputs are referenced to VCC(B), enabling true bidirectional voltage translation without external biasing.

The IOFF circuit actively disables outputs during power-down, blocking damaging backflow current when either VCC(A) or VCC(B) is at GND - placing both ports in high-impedance suspend mode. Propagation delay varies by supply combination: e.g., 5.9 ns (nAn→nBn) at VCC(A)=2.5 V / VCC(B)=3.3 V, and 11.8 ns (nBn→nAn) under same conditions, per -40 °C to +125 °C spec.

FAQ

What is the minimum operating voltage for VCC(A) and VCC(B)?

The absolute minimum supply voltage for both VCC(A) and VCC(B) is 0.8 V, with full functionality including IOFF, suspend mode, and JEDEC compliance guaranteed across the entire 0.8 V–3.6 V range. Operation below 0.8 V is not characterized and may result in undefined logic states or increased leakage.

How does the IOFF feature behave when only VCC(A) is powered?

When VCC(A) is active and VCC(B) = GND, the IOFF circuit disables all B-side outputs (1B1–1B8, 2B1–2B8), forcing them into high-impedance state while A-side I/O remains functional. This prevents backflow from A-side signals into the unpowered B-rail, satisfying IEC 61000-4-2 system-level ESD robustness requirements.

Can 74AVC16T245DGG,112 translate between 0.8 V and 3.3 V at 380 Mbit/s?

No - the 380 Mbit/s maximum data rate applies only to translation between ≥1.8 V and 3.3 V. At 0.8 V ↔ 3.3 V, the maximum rated speed is 200 Mbit/s per the datasheet's dynamic characteristics table, due to reduced noise margin and slower edge rates at the lowest VCC(A) setting.

Are all GND pins electrically identical and required to be connected?

Yes - all eight GND pins (4, 10, 15, 21, 28, 34, 39, 45) are internally bonded to the same die substrate and must be connected to a low-impedance system ground plane. Omitting any compromises EMI performance, thermal dissipation, and timing consistency across the 16-bit bus.
