TC7WH157FU,LJ(CT) — 产品概述

一、产品简介

TC7WH157FU 属于东芝 L‑MOS VHS 系列高速低功耗逻辑器件,面向对速度与静态功耗有较高要求的数字系统。器件为单电源供电,工作电压范围宽(2.0V 至 5.5V),适用于电池供电与多电平系统中作为数据选择/多路复用器使用(典型用途见后文)。封装为表面贴装 8 引脚(SM8),便于 PCB 高密度布置与自动化生产。

二、主要电气参数与性能

  • 电源极性:单电源
  • 工作电压范围:2.0 V ~ 5.5 V,宽电压兼容不同逻辑电平系统
  • 静态电流(Iq):典型 20 µA,低静态功耗利于待机与便携应用
  • 灌、拉电流能力:IOH = 8 mA,IOL = 8 mA,能够驱动一般的下一级 CMOS 负载或少量指示器
  • 传播延迟(tpd):典型 4.1 ns(在 VCC = 5.0 V,负载 15 pF 下测得),适合中高速数字链路
  • 工作温度范围:−40 ℃ ~ +85 ℃,满足工业级环境要求

以上参数表明该器件在保证高速响应的同时保持非常低的静态功耗,适合对延迟与功耗同时敏感的场景。

三、功能与应用场景

TC7WH157FU 常用作多路数据选择器/分配器,用于在多个数据源之间进行快速切换或在数据汇聚时进行通道选择。典型应用包括但不限于:

  • 数字信号切换与复用(CPU/FPGA 与外设间)
  • 低功耗便携设备中的数据路径选择
  • 多路输入的现场切换(传感器选择、外设多路接入)
  • 通用逻辑电平转换与信号重定向(在满足电平与驱动要求下)

四、使用与设计建议

  • 电源去耦:在器件电源引脚附近并联 0.1 µF 陶瓷电容,以抑制瞬态噪声并保证高速切换稳定性。
  • 负载与测量条件:传播延迟给出是在 15 pF 负载条件下的典型值。实际设计中若驱动更重负载或多级驱动,延迟会增加,应预留余量。
  • 驱动能力:IOH/IOL 为 8 mA,适合驱动高阻抗输入。若需驱动大电流负载,应使用缓冲或驱动级。
  • 工作温度与可靠性:器件工作温度覆盖工业级范围;在极端环境下建议做热管理与必要的可靠性验证。
  • 封装与焊接:SM8 表面贴装封装支持回流焊工艺,焊盘与过孔布线应遵循东芝封装说明书以获得良好热与电性能。

五、总结

TC7WH157FU 结合了 L‑MOS VHS 技术的高速特性与极低静态电流,单电源宽压特性及工业温度范围使其在便携与工业控制等多种场景中具备高适应性。设计中关注去耦、负载匹配及封装工艺,可充分发挥其在高速数据选择与低功耗应用中的优势。若需更详细的引脚排列、电气特性曲线及典型应用电路,建议参阅东芝原厂数据手册以获得完整规范与测试条件。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
