具有可配置电压转换和三态输出的 8 位双电源总线收发器

SN74LXCH8T245 是一款 8 位双电源同相双向电压电平转换器件，具有总线保持电路。 Ax 引脚和控制引脚（DIR 和 OE）以 VCCA 逻辑电平为基准，Bx 引脚以 VCCB 逻辑电平为基准。A 端口能够接受 1.1V 至 5.5V 的 I/O 电压，而 B 端口可接受 1.1V 至 5.5V 的 I/O 电压。如果 OE 设为低电平，DIR 上为高电平时允许数据从 A 传输到 B，DIR 上为低电平时允许数据从 B 传输到 A。OE 设为高电平时，Ax 和 Bx 引脚均处于高阻抗状态。请参阅器件功能模式，了解控制逻辑的运行摘要。 • 完全可配置的双电源轨设计可允许各个端口在 1.1V 至 5.5V 范围内运行\n• 在 3.3V 至 5.0V 范围内，支持高达 420Mbps 的速率\n• 施密特触发控制输入可实现慢速或高噪声输入\n• 高驱动强度（在 5V 时最高达 32mA）\n• 最大值 4µA (25°C)\n• VCC 隔离和 VCC 断开 特性 \n• Ioff-float 支持 VCC 断开操作\n• Ioff 支持局部断电模式运行\n• 控制逻辑（DIR 和 OE）以 VCCA 为基准\n• 闩锁性能超出 100mA，符合 JESD 78 II 类规范的要求\n• 4000V 人体放电模型\n•;
