Low voltage ultra-high speed comparator

GT8971


The GT897X series are low-power, ultra-high-speed comparators with internal hysteresis, which feature a fast 10ns propagation delay. These devices are optimized for single +3V or +5V operation, and consume only 2mA supply current. 

The GT897X series support rail-to-rail input and output operation. The input common mode voltage range is from -0.1V to (V+) +0.1V. The GT897X series have an internal hysteresis for reducing comparator sensitivity to noise, even when the input signals move slowly. 

All features are specified over the extended -40 ° C to +125°C temperature range.


Features

- Ultra-High speed: 10ns propagation delay

- Rail to Rail input and output 

- 6mV internal hysteresis for clean switching 

- Support CMOS or TTL logic - Supply range: +2.5 V to +5.5 V 

- Quiescent current: 2 mA per comparator



Applications


- High-speed line or digital line receivers 

- High speed sampling circuits 

- High-density systems 

- Threshold detectors 

- Portable equipment
