74LVC245A; 74LVCH245AOctal bus transceiver; 3-stateRev. 9 — 11 September 2018Product data sheet1. General descriptionThe 74LVC245A; 74LVCH245A are 8-bit transceivers featuring non-inverting 3-state buscompatible outputs in both send and receive directions. The device features an output enable(OE) input for easy cascading and a send/receive (DIR) input for direction control. OE controls theoutputs so that the buses are effectively isolated.Inputs can be driven from either 3.3 V or 5 V devices. When disabled, up to 5.5 V can be applied tothe outputs. These features allow the use of these devices in mixed 3.3 V and 5 V applications.The 74LVCH245A bus hold on data inputs eliminates the need for external pull-up resistors to holdunused inputs.2.

关于驱动芯片国产化替代方案研究发布时间：2022-01-12T02:58:04.070Z 来源：《现代电信科技》2021年第13期作者：邹宇[导读] 随着电子元器件的要求不断提高，但进口元器件存在国外禁运，停产断档的问题，还存在多种安全风险、质量与可靠性隐患及自主保障问题，为提升自主可控能力，必须寻求国产化替代。

（航天风华精密设备有限公司）摘要：面对芯片短缺给智能产业带来的影响，芯片国产化替代步伐也在不断加快。

本文从军用电子元器件国产化需求出发，并对 2 种驱动芯片为具体案例，给出国产化替代的方案，对该国产化驱动芯片进行分析，可确定为该国产化驱动芯片可功能替代进口驱动芯片。

1 引言随着电子元器件的要求不断提高，但进口元器件存在国外禁运，停产断档的问题，还存在多种安全风险、质量与可靠性隐患及自主保障问题，为提升自主可控能力，必须寻求国产化替代。

2 芯片简介本文对 SN74LVC4245APWR、SN74LVC573ADB 两种驱动芯片进行具体分析，该芯片为美国德州仪器生产，本文拟采用北京华芯微生产的 HRLVC4245M、HRALS573M 进行替代，并从电气参数、外形封装、管脚定义、质量等级、环境使用能力等方面进行分析比较。

2.1 驱动芯片 SN74LVC4245APWR 国产化替代方案SN74LVC4245APWR 是三态电平转换驱动器芯片，具有三态输出功能，实现双向的 8 位数据传输及电平转换功能，并可 3.3V 和5.0V 信号的转换。

该芯片主要用于连接串口控制器和光耦以及驱动芯片 174 之间进行电压转换，其具体电路见图 1。

图 1 SN74LVC4245APWR 的电路应用拟采用北京华芯微生产的 HRLVC4245M 进行替换。

该器件质量保证等级为 B 级，封装形式为 CSOP24 陶瓷封装。

原进口器件与拟替代的国产器件主要参数对比见表 1 所示。

DescriptionThe 74LVC240A provides two 4-bit buffers/drivers with separate output-enable (OE) inputs. When OE is low, the device passes data from the A inputs to the Y outputs. When OE is high, the outputs are in the high-impedance state.The device is designed for operation with a powersupply range of 1.65V to 3.6V.The inputs are tolerant to 5.5V allowing this device to be used in a mixed voltage environment. The device is fully specified for partial power down applications using I OFF . The I OFF circuitry disables the output preventing damaging current backflow when the device is powered down.Features∙ Supply Voltage Range from 1.65V to 3.6V ∙ Sinks or Sources 24 ma at V CC = 3V ∙ CMOS Low Power Consumption∙ I OFF Supports Partial -Power Down Operation∙ Inputs or Outputs Accept up to 5.5V∙ Inputs Can Be Driven by 3.3V or 5V Allowing for Mixed Voltage Applications∙ Schmitt Trigger Action at All Inputs∙ Typical V OLP (Quiet Output Ground Bounce) Less than 0.8V with V CC = 3.3V and T A = +25°C∙ Typical V OHV (Quiet Output dynamic VOH) Greater than 2.0V with V CC = 3.3V and T A = +25°C∙ESD Protection Tested per JESD 22▪ Exceeds 200-V Machine Model (A115)▪ Exceeds 2000-V Human Body Model (A114) ▪ Exceeds 1000-V Charged Device Model (C101) ∙ Latch-Up Exceeds 250mA per JESD 78, Class I ∙All devices are:▪ Totally Lead-Free & Fully RoHS compliant (Notes 1 & 2) ▪ Halogen and Antimony Free.“Green” Device (Note 3)Pin Assignments(Top View )TSSOP-20Top Transparent View 3245678913141217181615191120110V c c2OE 1Y22A42A31Y32A21Y42A 11Y1G N D1O E1A22Y42Y31A32Y21A42Y11A1QFN-20()terminal 1 index areaApplications∙ General Purpose Logic ∙ Bus Driving∙ Power Down Signal Isolation ∙Wide Array of Products Such as:▪ PCs, Notebooks, Netbooks, Ultrabooks▪ Networking Computer Peripherals, Hard Drives, CD/DVDROM▪ TV, DVD, DVR, Set Top BoxNotes: 1.
