TP1961

概述

The TP1961/TP1962/TP1964 are low-power, ultrahigh-speed comparators with internal hysteresis. These devices are optimized for single +3V or +5V operation. The input common-mode range extends 300mV beyond the rail, and the outputs can sink or source 4mA to within 80mV of GND and VCC. Propagation delay is 7ns (50mV overdrive), while supply current is 1mA per comparator.

The internal input hysteresis eliminates output switching due to internal input noise voltage, reducing current draw. The push-pull output supports rail-to-rail output swing, and interfaces with CMOS/TTL logic. The output toggle frequency can reach a typical of 50 MHz while limiting supply current surges and dynamic power consumption during switching.

The TP1961 single comparators are available in shout-down function, and the tiny SOT23 package for space-conservative designs. All devices are specified for the temperature range of –40°C to +125°C.
