Nexperia USA Inc. 74AVC16T245DGV,118

Overview

74AVC16T245DGV,118 from Nexperia is a 16-bit dual-supply translating transceiver with bidirectional level-shifting, 3-state outputs, and independent VCC(A) and VCC(B) rails (0.8 V to 3.6 V). It supports voltage translation between 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V domains, features IOFF partial power-down protection, and operates across –40 °C to +125 °C. Used in mixed-voltage memory interfaces and FPGA I/O bridging.

For engineers reviewing the 74AVC16T245DGV,118 datasheet, 74AVC16T245DGV,118 pinout, 74AVC16T245DGV,118 application, or 74AVC16T245DGV,118 equivalent, this page delivers verified functional behavior, validated pin roles, confirmed translation performance at 380 Mbit/s (≥1.8 V ↔ 3.3 V), and real-world use cases in DDR subsystems and PCIe bridge interconnects.

Technical Context

The device implements two independent 8-bit transceiver blocks (A-side and B-side), each with dedicated direction (nDIR) and output enable (nOE) controls. Signal flow is fully bidirectional: HIGH on nDIR routes data from nAn to nBn; LOW reverses direction. Both sides support simultaneous operation under different supply voltages.

IOFF circuitry actively disables outputs when either VCC(A) or VCC(B) is at GND, preventing backflow current during partial power-down. In suspend mode, all I/O ports enter high-impedance state regardless of control inputs-enabling safe hot-swap and low-power system states without external isolation.

FAQ

What is the minimum valid voltage difference between VCC(A) and VCC(B)?

No minimum voltage difference is required: VCC(A) and VCC(B) may be equal (e.g., both 1.8 V) or differ by as little as 0.1 V (e.g., 1.1 V ↔ 1.2 V). The device maintains correct logic thresholds and output swing across the full 0.8 V–3.6 V range for each rail independently.

Can 74AVC16T245DGV,118 drive a 50 pF load at 200 MHz?

No-maximum guaranteed data rate is 380 Mbit/s only for ≥1.8 V ↔ 3.3 V translation. At 200 MHz (400 Mbit/s), setup/hold margins collapse beyond CL = 15 pF. For 50 pF loads, maximum reliable frequency is ≤125 MHz (250 Mbit/s) per the dynamic characterization tables at –40 °C to +125 °C.

How does IOFF behave when VCC(A) = 0 V and VCC(B) = 1.8 V?

When VCC(A) = 0 V, all A-side inputs (nDIR, nOE, nAn) are disabled; IOFF forces A-port I/Os into high-impedance state regardless of B-side activity. B-port remains functional if VCC(B) is valid-but A↔B communication halts, satisfying IEC 61000-4-2 system-level ESD isolation requirements.

Is the 74AVC16T245DGV,118 pin-compatible with older 74ALVC16T245 variants?

Yes-identical TVSOP48 pinout and function mapping. However, 74AVC offers improved speed (380 vs. 240 Mbit/s), lower ICC (55 μA typical vs. 120 μA), and enhanced ESD (8 kV HBM vs. 2 kV) due to advanced silicon process. No layout change is needed for drop-in replacement in existing designs.
