Typical Single Supply Voltage

1.7 → 5.5 V

The STMicroelectronics TS3121 and the TS3121A single comparators permit high-speed response time at low power consumption over a supply voltage specified from 1.7 to 5.5 V. These devices operate over a wide temperature range from -40 °C to +125 °C making them ideal for industrial and automotive applications with the associated qualification. Thanks to an embedded fail-safe circuit, the TS3121 and the TS3121A can operate with input/output pins biased while the supply pin is shut down to VCC = 0 V for energy saving applications. A guaranteed start-up time ensures a stable output condition after activating the supply rail.

Low offset voltage 2 mV max 25°C A-grade version
Low power consumption 70 μA typ
Wide supply voltage 1.7 to 5.5 V
Propagation delay 60 ns
Fail safe input and output pins
Input and output pins withstand voltages higher than VCC
Fail safe architecture keeps output in high impedance when VCC = 0 V
Guaranteed start up time allows sequential on or off cycles of VCC
High ESD tolerance 4 kV HBM
Extended temperature range -40 to +125 °C
