MAX9144ESD

为40ns ，低功耗， 3V / 5V ，轨到轨单电源比较器 40ns, Low-Power, 3V/5V, Rail-to-Rail Single-Supply Comparators

General Description

The MAX9140/MAX9141 are single and the MAX9142/MAX9144 are dual/quad high-speed comparators optimized for systems powered from a 3V or 5V supply. The MAX9141 features latch enable and device shutdown. These devices combine high speed, low power, and rail-to-rail inputs. Propagation delay is 40ns, while supply current is only 150µA per comparator.
