description
This device is fabricated using LinCMOS
technology and consists of two independent
voltage comparators, each designed to operate
from a single power supply. Operation from dual
supplies is also possible if the difference between
the two supplies is 1.4 V to 18 V. Each device
features extremely high input impedance
(typically greater than 10
12
), which allows direct
interface to high-impedance sources. The output
are n-channel open-drain configurations and can
be connected to achieve positive-logic wired-AND
relationships. The capability of the TLC352 to
operate from 1.4-V supply makes this device ideal
for low-voltage battery applications.
The TLC352 has internal electrostatic discharge (ESD) protection circuits and has been classified with a 2000-V
ESD rating tested under MIL-STD-883C, Method 3015. However, care should be exercised in handling this
device as exposure to ESD may result in degradation of the device parametric performance.
The TLC352C is characterized for operation from 0
°
C to 70
°
C. The TLC352I is characterized for operation over
the industrial temperature range of – 40
°
C to 85
°
C. The TLC352M is characterized for operation over the full
military temperature range – 55
°
C to 125
°
C.
