CXCO4323双通道高速比较器为3V或5V电源供电的系统而优化有高速响应低功耗轨对轨输入范围和开漏输出等特点传输延迟为150ns电源电流仅为22μA/通道输入共模范围超出了两个电源轨

CXCO4323是一款双通道高速比较器，专为3V或5V电源供电的系统而优化。该装置具有高速响应、低功耗、轨对轨输入范围和开漏输出等特点。传输延迟为150ns，而电源电流仅为22μA/通道。
CXCO4323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，输出电压可拉至任一供电轨的0.1V以内，使该器件非常适合与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。

•快速，150ns传播延迟（10mV超速）
•低功耗：
VS=3V时22μA/通道（典型值）
•宽电源电压范围：2.7V至5.5V
•针对3V和5V应用优化
•开漏输出
•轨对轨输入电压范围
•低偏移电压：0.8mV（典型值）
•输出摆幅185mV，输出电流4mA
•CMOS/TTL兼容输出

The CXCO4323 is a dual channels 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 and open drain output. Propagation delay is 150ns, while supply current is only 22μA/channel.

The input common mode range of the CXCO4323 extends beyond both power supply rails. The output pulls 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.

The CXCO4323 is available in Green MSOP-8 and SOIC-8 packages. It is rated over the -40℃ to +85℃ temperature range.
