DUAL MICROPOWER LinCMOS™ VOLTAGE COMPARATORS
SLCS013E − NOVEMBER 1986 − REVISED MARCH 2012
APPLICATION INFORMATION
The inputs should always remain within the supply rails in order to avoid forward biasing the diodes in the
electrostatic discharge (ESD) protection structure. If either input exceeds this range, the device is not damaged
as long as the input is limited to less than 5 mA. To maintain the expected output state, the inputs must remain
within the common-mode range. For example, at 25°C with V_DD = 5 V, both inputs must remain between
−0.2 V and 4 V to ensure proper device operation.
To ensure reliable operation, the supply should be decoupled with a capacitor (0.1 μF) that is positioned as close
to the device as possible.
The TLC3702 has internal ESD-protection circuits that prevent functional failures at voltages up to 2000 V as
tested under MIL-STD-883C, Method 3015.2; however, care should be exercised in handling these devices as
exposure to ESD may result in the degradation of the device parametric performance.
