PCAL6416APW,118 产品概述
一、概述
PCAL6416APW,118 是恩智浦（NXP）推出的一款 16 路 I/O 扩展器，支持 I2C/SMBus 通讯（最高 400 kHz），适用于需要增加 GPIO 数量、LED 驱动与电平兼容的系统。器件提供中断输出与复位功能，支持级联与地址扩展，工作电压范围宽（1.65V ～ 5.5V），工作温度 -40℃ ～ +85℃，封装为 TSSOP-24，适合工业与消费类产品。
二、主要特性
- 接口：I2C / SMBus（400 kHz 快速模式），简化与主控制器的总线连接。
- I/O 数量：16 路通用 I/O，可配置为输入或输出，IO 电平可配置以适应不同逻辑电平。
- 输出类型：支持推挽式与开漏输出；开漏输出适合总线/线驱动与级联功能。
- 驱动能力：每通道下拉/灌电流 IOL 达 25 mA，适合直接驱动小型 LED 或指示灯。
- 中断与复位：提供中断输出，支持事件触发减少主机轮询；内置复位功能提升系统可靠性。
- 低功耗：静态电流仅 1.5 μA，适合电池供电与低功耗设计。
- 地址扩展：支持级联与地址扩展（支持 2 个器件），便于扩展更多 I/O。
三、电气与封装信息
- 工作电压：1.65 V ～ 5.5 V，支持不同电压域间的电平兼容与移位。
- 时钟频率：最高 400 kHz，满足多数嵌入式与工业 SMBus/I2C 应用的速度需求。
- 工作温度：-40℃ ～ +85℃，适合严苛环境。
- 包装：TSSOP-24（PCAL6416APW），适合 PCB 密度与自动贴装工艺。
- 品牌：NXP（恩智浦）。
四、典型应用
- LED 指示与背光驱动（小功率 LED 指示灯）。
- 按键矩阵与键盘扫描，扩展 MCU/MPU 的输入端口。
- 工业控制与楼宇自动化中对 I/O 数量扩展的需求。
- 电平域隔离和接口转换场景（多电压系统的 GPIO 扩展）。
- 需要低功耗待机并具备中断唤醒的便携设备。
五、设计与选用建议
- 若需直接驱动较多或大电流 LED，应评估总耗电与热设计，必要时外接驱动器或限流电阻。
- 利用中断功能可显著降低主控器的轮询负担，提高系统能效与响应性。
- 在多器件并联时，注意地址配置与总线电容限制，保持 I2C 总线完整性（上拉电阻选择与走线布线）。
- 推荐在设计评审时参考厂商数据手册获取寄存器映射、电气特性曲线与典型应用电路，以确保兼容性与可靠性。
PCAL6416APW,118 以其低功耗、可配置输出、宽电压范围与内置 LED 驱动等特性，是对 I/O 资源有扩展需求且需兼顾功耗与可靠性的系统的理想选择。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
