[Product Release] GT895X Series Low-Voltage High-Speed Comparators
2025-06-26 10:47:13
Product
The GT895X series consists of low-power, high-speed comparators with internal hysteresis and a propagation delay of just 18ns. These devices are suitable for both 3V and 5V systems and consume only 160μA of quiescent current.
The GT895X series supports rail-to-rail input and output, with a common-mode input voltage range from -0.1V to (V+)+0.1V. The built-in hysteresis enhances noise immunity, even with slowly varying input signals, making the series well-suited for interfacing with CMOS and TTL logic circuits.
In terms of packaging:
GT8951 is available in SC70-5 and SOT23-5 packages.
GT8952 is available in MSOP8 and SOP8 packages.
GT8954 is available in TSSOP14 and SOP14 packages.
