MICROPOWER QUAD COMPARATORS

POST OFFICE BOX 655303
DALLAS, TEXAS 75265
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 current 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
assure proper device operation. To assure reliable operation, the supply should be decoupled with a capacitor (0.1
μ
F) positioned as close to the device as possible.
The output and supply currents require close observation since the TLC139/TLC339 does not provide current
protection. For example, each output can source or sink a maximum of 20 mA; however, the total current to ground
has an absolute maximum of 60 mA. This prohibits sinking 20 mA from each of the four outputs simultaneously since
the total current to ground would be 80 mA.
The TLC139 and TLC339 have internal ESD-protection circuits that prevent functional failures at voltages up to
2000 V as tested under MIL-STD-883C, Method 3015.2; however, exercise care when handling these devices as
exposure to ESD may result in the degradation of the device parametric performance.
