SGM8740X中文资料42ns, 3V/5V, Single-Supply, Low Power, Rail-to-Rail I/O Comparator数据手册SGMICRO规格书

描述 Description

The SGM8740X is a single, high speed, low power comparator, which features a fast 42ns propagation delay. The device is optimized for low voltage operation on 3V or 5V supply, and consumes only 155μA supply current.
The SGM8740X supports rail-to-rail input and output operation. The input common mode voltage range is from -0.1V to (+VS) + 0.1V, and the output voltage swing is within 210mV of the rails without external pull-up or pull-down resistor. The device can be compatible with CMOS and TTL logics. Any input or output pin has a continuous short-circuit protection to both power supply rails. The SGM8740X has an internal hysteresis for reducing comparator sensitivity to noise, even when the input signals move slowly.
The SGM8740X is available in Green SOT-23-5 and SC70-5 packages. It is rated over the -40℃ to +125℃ temperature range.
