SN74AVCH4T245RGYR TI Voltage Level Translator | 16-VQFN (4x3.5) | 4-bit, 1.2-3.6V

Product Overview

The SN74AVCH4T245RGYR is a 4-bit non-inverting bus transceiver from Texas Instruments, designed for asynchronous communication between two voltage nodes. It features dual-supply voltages (VCCA and VCCB) ranging from 1.2V to 3.6V, enabling bidirectional level translation for mixed-voltage systems. The device is housed in a compact 16-pin VQFN package (4mm x 3.5mm) with a 0.5mm pitch, ideal for space-constrained applications. It supports partial power-down mode (Ioff) to prevent backflow current when one supply is off, and offers ±24-mA output drive at 3.3V VCC.

Detailed Technical Specifications

Key Features

• Bidirectional voltage level translation between 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V nodes
• High-speed operation with typical propagation delay of 2.5 ns
• Partial power-down mode (Ioff) prevents backflow current
• Low static power consumption (max 40 µA)
• ESD protection exceeds JESD 22 (2000-V HBM, 1000-V CDM)
• Small footprint VQFN package saves board space

Target Applications

• 5G base station control boards (e.g., interfacing FPGA with 1.8V logic to 3.3V peripheral)
• Automotive dashboard displays (e.g., connecting 1.8V MCU to 3.3V display driver)
• Industrial PLC modules (e.g., level translation between 2.5V sensor and 3.3V controller)
• Portable electronics (e.g., battery-powered IoT devices with mixed-voltage sensors)
• Networking equipment (e.g., router line cards with 1.2V core and 3.3V I/O)

產品概述

SN74AVCH4T245RGYR 是德州儀器（TI）推出的4位非反相匯流排收發器，專為兩個電壓節點之間的非同步通訊設計。它具有雙電源電壓（VCCA 和 VCCB），範圍從 1.2V 到 3.6V，支援混合電壓系統的雙向電平轉換。器件採用緊湊的 16 引腳 VQFN 封裝（4mm x 3.5mm，間距 0.5mm），適合空間受限的應用。它支援部分斷電模式（Ioff），可在一個電源關閉時防止反向電流，並在 3.3V VCC 下提供 ±24-mA 的輸出驅動能力。
