CD40109BNSR TI Voltage-Level Shifter | 16-SO | 3-18V, 4-Channel

Product Overview

The CD40109BNSR from Texas Instruments is a quad low-to-high voltage level shifter designed to convert input signals from a low voltage domain (e.g., 3V or 5V) to a higher voltage output domain (up to 18V). It features four independent level-shifting channels, each with a non-inverting buffer. The device operates from a single supply voltage (VCC) for the input side and a separate supply (VDD) for the output side, allowing flexible voltage translation. Housed in a 16-pin SO package (NS suffix), it is suitable for space-constrained applications requiring reliable level shifting.

Detailed Technical Specifications

Key Features

• Quad independent level-shifting buffers
• Wide supply voltage range: 3 V to 18 V for both VCC and VDD
• Low power consumption
• High noise immunity
• Standardized symmetrical output characteristics
• ESD protection exceeds 2000 V per MIL-STD-883

Target Applications

The CD40109BNSR is ideal for interfacing between different voltage domains in systems such as 5G base stations (e.g., translating control signals from a 3.3V FPGA to 5V RF switches), automotive dashboards (e.g., converting 5V sensor outputs to 3.3V microcontroller inputs), industrial PLCs (e.g., level shifting for 24V I/O modules), and battery management systems (e.g., translating voltage levels between a 3V MCU and 12V battery monitoring ICs).

產品概述

CD40109BNSR 是德州儀器（TI）推出的四路低電壓到高電壓電平轉換器，專為將輸入信號從低電壓域（例如 3V 或 5V）轉換為更高電壓的輸出域（最高 18V）而設計。它包含四個獨立的電平轉換通道，每個通道均為同相緩衝器。該器件使用單電源（VCC）供給輸入側，並使用獨立電源（VDD）供給輸出側，從而實現靈活的電壓轉換。採用 16 引腳 SO 封裝（NS 後綴），適用於需要可靠電平轉換的空間受限應用。

詳細技術參數

核心特性

• 四路獨立電平轉換緩衝器
• 寬電源電壓範圍：VCC 和 VDD 均為 3 V 至 18 V
• 低功耗
• 高抗噪性
• 標準化對稱輸出特性
• ESD 保護超過 2000 V（符合 MIL-STD-883）

典型應用場景

CD40109BNSR 非常適合在不同電壓域之間進行接口轉換，例如 5G 基站（將 3.3V FPGA 的控制信號轉換為 5V 射頻開關）、汽車儀表板（將 5V 傳感器輸出轉換為 3.3V 微控制器輸入）、工業 PLC（為 24V I/O 模塊進行電平轉換）以及電池管理系統（在 3V MCU 和 12V 電池監控 IC 之間轉換電壓電平）。
