Dual Low Voltage LinCMOS™ Differential Comparator

The TLV2352 consists of two independent, lowpower

comparators specifically designed for single

power-supply applications and operates with powersupply

rails as low as 2V (2.7V TLV2352IDR and

TLV2352IPWR only). When powered from a 3V

supply, the typical supply current is only 120µA.

The TLV2352 is designed using the Texas

Instruments CMOS technology and therefore features

an extremely high input impedance (typically greater

than 1012Ω), 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 can be connected to achieve positivelogic

wired-AND relationships. The TLV2352I is fully

characterized at 3V and 5V for operation from –40°C

to 85°C. The TLV2352M is fully characterized at 3V

and 5V for operation from –55°C to 125°C.

The TLV2352 has internal electrostatic discharge

(ESD) protection circuits and has been classified

with a 1000V ESD rating using Human Body Model

testing. However, care must be exercised in handling

this device as exposure to ESD can result in

degradation of the device parametric performance.
