CXCO4321是一款双高速比较器，针对3V或5V电源供电的系统进行了优化。该设备具有高速响应、低功耗和轨对轨输入范围。传输延迟为155ns，而电源电流仅为45μA。
CXCO4321的输入共模范围超出了两个电源轨。在没有外部上拉电路的情况下，输出拉至任一电源轨的0.1V以内，使得该器件非常适合与CMOS和TTL逻辑接口。所有输入和输出引脚都能承受任何一条轨道的持续短路故障。内部滞后确保了干净的输出开关，即使是慢动作的输入信号。
CXCO4321提供绿色SOIC-8和MSOP-8封装。额定温度在-40℃到+85℃之间。

产品概述 返回TOP
The CXCO4321 is a dual high-speed comparator optimized for systems powered from a 3V or 5V supply. The device features high-speed response, low-power consumption, and rail-to-rail input range. Propagation delay is 155ns, while supply current is only 45μA.
The input common mode range of the CXCO4321 extends beyond both power supply rails. The outputs pull to within 0.1V of either supply rail without external pull-up circuitry, making the device ideal for interface with both CMOS and TTL logics. All input and output pins can tolerate a continuous short-circuit fault condition to either rail. Internal hysteresis ensures clean output switching, even with slow-moving input signals.
The CXCO4321 is available in Green SOIC-8 and MSOP-8 packages. It is rated over the -40℃ to +85℃ temperature range.
