The TLV2352 consists of two independent,
IN +
low-power comparators specifically designed for
OUT
single power-supply applications and operates
IN –
with power-supply rails as low as 2 V. When
powered from a 3-V supply, the typical supply
current is only 120 µA.
The TLV2352 is designed using the Texas Instruments LinCMOS™ technology and therefore features an extremely high input impedance (typically greater than 1012 Ω), which allows direct interfacing with high-impedance sources. The outputs are N-channel open-drain configurations that require an external pullup
resistor to provide a positive output voltage swing, and they can be connected to achieve positive-logic
wired-AND relationships. The TLV2352I is fully characterized at 3 V and 5 V for operation from – 40°C to 85°C. The TLV2352M is fully characterized at 3 V and 5 V for operation from – 55°C to 125°C.
The TLV2352 has internal electrostatic-discharge (ESD)-protection circ...
