description
The TLV2352 consists of two independent,
low-power comparators specifically designed for
single power-supply applications and operates
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
12
extremely high input impedance (typically greater than 10 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 circuits and has been classified with a
1000-V ESD rating using Human Body Model testing. However, care should be exercised in handling this device
as exposure to ESD may result in degradation of the device parametric performance.

The D package is available taped and reeled. Add the suffix R to the device type (e.g., TLV2352IDR).
The PW packages are only available left-ended taped and reeled (e.g., TLV2352IPWLE)
These devices have limited built-in protection. The leads should be shorted together or the device placed in conductive foam during
storage or handling to prevent electrostatic damage to the MOS gates.
