CXCO4332此4位非垂直转换器使用两个单独的可配置电源轨。A端口设计用于跟踪VCCA。VCCA接受1.2V到3.6V的任何电源电压。B端口设计用于跟踪VCCB。VCCB接受1.65V到5.5V的任何电源电压。这允许在1.2V、1.5V、1.8V、2.5V、3.3V和5V电压节点之间进行通用低压双向转换。VCCA不应超过VCCB。当使能输出（EO）输入低时，所有输出都处于高阻抗状态。为了确保在通电或断电期间的高阻抗状态，EO应通过下拉电阻器连接到GND；电阻器的最小值由驱动器的电流源能力决定。CXCO4332的设计使得EO输入电路由VCCA提供。此设备完全指定用于使用“关闭”的部分关机应用程序。断开电路会禁用输出，防止设备断电时损坏的电流回流。

产品概述 返回TOP
This 4-bit noninverting translator uses two separate configurable power-supply rails. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.2V to 3.6V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65V to 5.5V. This allows for universal low-voltage bidirectional translation between any of the 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5V voltage nodes. VCCA should not exceed VCCB. When the enable-output (EO) input is low, all outputs are placed in the high-impedance state. To ensure the high-impedance state during power up or power down, EO should be tied to GND through a pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver. The CXCO4332 is designed so that the EO input circuit is supplied by VCCA. This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
