概要

Description

The SN74AVC16T245DGG is TI’s 16‑bit, dual‑supply bidirectional bus transceiver and level shifter (AVC family). It translates data between two voltage domains (A side at VCCA and B side at VCCB) and buffers the data with 3‑state outputs.
Key features
- 16 independent data lines with bidirectional A↔B translation
- DIR pin selects direction (A→B or B→A)
- OE (output enable) to tri‑state both sides
- Operates between two supply rails, enabling easy interfacing of mixed‑voltage devices
Package code DGG indicates the specific TI package variant. Typical use cases
- Bridging buses between microcontrollers/MISs at different voltages (e.g., 1.8/3.3 V to 3.3/5 V)
- Interfaces between FPGAs, memories, sensors, and other peripherals across voltage rails
In short, it’s a wide, 16‑bit, two‑supply bus translator with controllable direction and tri‑state outputs for flexible mixed‑voltage systems.

Features

Here are the key features of SN74AVC16T245DGG:
- 16‑bit bidirectional bus transceiver with two 8‑bit sides (A and B)
- Dual-supply translation: VCCA and VCCB from 1.65 V to 3.6 V
- Direction control via DIR and enable via OE; 3‑state outputs
- Ioff supports partial‑power‑down (no back‑powering when one side is unpowered)
- Suitable for level shifting between different voltage domains; broad I/O compatibility
- Industrial temperature range: typically -40°C to 85°C
- Package: DGG (TI packaging code, e.g., TSSOP/VQFN family)
- Common use: bidirectional data interfacing, microcontroller/memory/bus systems requiring voltage translation
Optional notes:
- No auto-direction sensing; direction controlled by DIR
- Designed for low power and fast switching in mixed‑voltage systems

Package

The SN74AVC16T245DGG is supplied in a 48-pin VQFN (DGG) package, 6.0 mm × 6.0 mm with an exposed thermal pad.

Pinout

Pin count: 48 pins (DGG = 48-pin VQFN package).
Function (concise):
- 16-bit non‑inverting bidirectional bus transceiver/voltage‑level translator.
- Provides 16 A-side pins (A1–A16) and 16 B-side pins (B1–B16).
- Direction control via DIR input (selects A→B or B→A).
- Active‑low output enable (OE) to tri‑state outputs.
- Dual power rails (VCCA and VCCB) for interfacing different logic voltage domains; ground (GND) and thermal pad present.

Manufacturer

Manufacturer: Texas Instruments Incorporated (TI).
Type of company: TI is an American multinational semiconductor company that designs and manufactures integrated circuits and other electronic components (analog and digital ICs, embedded processors, power management, etc.), with global R&D, manufacturing (wafer fabs), and distribution operations.

Application

SN74AVC16T245DGG applications:
- Level shifting between voltage domains (A-side low voltage, B-side higher voltage)
- 16-bit bidirectional bus transceiver for MCUs/FPGA, memories, and peripherals
- I/O expansion with tri-state control on shared buses and backplanes
- Mixed-voltage automotive/industrial systems requiring bus isolation and flexible data paths

Equivalent

Direct equivalents are the generic 74AVC16T245 offered by other vendors (Nexperia, ON Semiconductor, Diodes Inc., STMicro). Functional alternatives include using two 8-bit translators (e.g. SN74AVC8T245 pair) or other bi‑directional level‑translator families such as TXB0108 / TXS0108E (8‑bit auto‑directional) or a 16‑bit bus transceiver from the 74LVC/74ALVT families—choose based on direction control, speed and VCCA/VCCB requirements.
