PIN DESCRIPTION
Pin Name Type Description
1 OUT 1 Output Output of comparator 1. The open−drain output requires an external pull−up resistor.
2 IN− 1 Input Inverting input of comparator 1
3 IN+ 1 Input Non−inverting input of comparator 1
4 VSS Power Negative supply
5 IN+ 2 Input Non−inverting input of comparator 2
6 IN− 2 Input Inverting input of comparator 2
7 OUT 2 Output Output of comparator 2. The open−drain output requires an external pull−up resistor.

Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality
should not be assumed, damage may occur and reliability may be affected.
1. Stresses beyond the absolute maximum ratings can lead to reduced reliability and damage.
2. Excursions of input voltages may exceed the power supply level. As long as the common mode voltage [V
CM
= (V
IN
+ + V
IN
−)/2] remains
within the specified range, the comparator will provide a stable output state. However, the maximum current through the ESD diodes of the
input stage must strictly be observed.
3. Input differential voltage is the non−inverting input terminal with respect to the inverting input terminal. To prevent damage to the gates, each
comparator includes back−to−back zener didoes between input terminals. When differential voltage exceeds 6.2 V, the diodes turn on. Input
resistors of 1 kW have been integrated to limit the current in this event.
4. This device series incorporates ESD protection and is tested by the following methods:
ESD Human Body Model tested per AEC−Q100−002 (JEDEC standard: JESD22−A114)
ESD Machine Model tested per AEC−Q100−003 (JEDEC standard: JESD22−A115)
Latch−up Current tested per JEDEC standard: JESD78.
