SN74CBTLV3125中文资料具有断电保护功能的 3.3V、1:1 (SPST)、4 通道 FET 总线开关数据手册TI规格书

描述 Description

The SN74CBTLV3125 quadruple FET bus switch features independent line switches. Each switch is disabled when theassociated output-enable (OE\\) input is high.

This device is fully specified for partial-power-down applications using Ioff. The Ioff feature ensures that damaging current will not backflow through the device when it is powered down. The device has isolation during power off.

To ensure the high-impedance state during power up or power down, OE\\ should be tied to VCC through apullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

特性 Features

• Standard ’125-Type Pinout
• 5- Switch Connection Between Two Ports
• Rail-to-Rail Switching on Data I/O Ports
• Ioff Supports Partial-Power-Down Mode Operation
• Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II

简介

SN74CBTLV3125属于集成电路（IC）的信号开关多路复用器解码器。由TI制造生产的SN74CBTLV3125信号开关，多路复用器，解码器逻辑型信号开关、多路复用器和编码器 IC 可用于对以数字格式表示数据的电信号进行路由和选择。这些器件与设计用于模拟信号的类似产品有所不同，它们保留的信息表示为两个电状态之一，而不是两个外部界限内的无穷变化量。
