产品

概览

LVT162245 和 LVTH162245 包含十六个带有 3 态输出的非反相双向缓冲器，适用于总线导向型应用。此器件为字节控制。每个字节有单独的控制输入，可一起缩短以实现完整的 16 位操作。T/R# 输入决定数据流经该器件的方向。OE# 输入将 A 和 B 端口置于高阻抗状态，从而将两者禁用。LVT162245 和 LVTH162245 设计为在 A 端口输出的 “高电平”和“低电平”状态下具有等效的 25Ω 串联电阻。此设计减少了应用中的线路噪声，例如内存地址驱动器、时钟驱动器和总线收发器/发射器。LVTH162245 数据输入包含总线槽，无需外部上拉电阻来保存未使用的输入。这些非反相收发器适用于低压 (3.3V) VCC 应用，能够提供连接到 5V 环境的 TTL 接口。LVT162245 和 LVTH162245 采用先进的 BiCMOS 工艺，可实现与 5V ABT 类似的高速运行，同时保持低功耗。

  • This product is general usage and suitable for many different applications.

  • 系统在5V VCC时的输入和输出接口能力
  • 总线保持数据输入无需外部上拉电阻即可保持未用的输入(74LVTH162245)，另外还提供不含总线保持功能的配置(74LVT162245)。
  • 允许带电插/拔
  • 上电/掉电高阻抗提供无干扰总线负载
  • A端口输出包含25ohm等效串联电阻，无需外部终端电阻，还可减少过冲和欠冲
  • A端口输出源电流/灌电流为±12 mA。 A端口输出源电流/灌电流为-32 mA/+64 mA
  • 功能上兼容74系列162245
  • 闩锁性能超过500 mA
  • 静电放电(ESD)性能：人体模型> 2000V机械模型> 200V充电器件模型> 1000V
  • 同样采用塑料微间距球栅阵列(FBGA)封装
