description
The TLV2354 consists of four 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 240
A.
The TLV2354 is designed using the Texas Instruments LinCMOS
TM
technology and, therefore, features an
extremely high input impedance (typically greater than 10
12
), 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 TLV2354I is fully characterized for operation from 40
C to 85
C. The TLV2354M
is fully characterized for operation from 55
C to 125
C.
The TLV2354 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., TLV2354IPW).
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.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES:
1. All voltage values, except differential voltages, are with respect to network ground.
2. Differential voltages are at the noninverting input terminal with respect to the inverting input terminal.
3. Short circuits from outputs to VDD can cause excessive heating and eventual device destruction.
