DESCRIPTION
N
DIP14
(Plastic Package)
D
SO14
(Plastic Micropackage)
These products are precision high speed dual
comparatorsdesignedto operate overa wide range
of supply voltages down to a single 5V logic supply
and ground and have low input currents and high
gains.
The open collector of the output stage makes
compatible with TTL as well as capable of driving
lamps and relays at currents up to 25mA.
ORDER CODES
Although designed primarily for applications
requiring operation from digital logic supplies, are
fully specified for power supplies up to ±15V.
They featurefaster response thanthe LM111 at the
expenseof higherpower dissipation. However, the
high speed, wide operating voltage range and low
packagecount make the much more versatile.

Notes : 1. For supply voltages less than ±15V the absolute maximum input voltage is equal to the supply voltage.
2. These specifications apply for VCC = ±15V, unless otherwise stated. The offset voltage, offset current and
bias current specifications apply for any supply voltage from a single +5V supply up to ±15V supplies.
The offset voltages and offset current given are the maximum values required to drive the output down to 1V
or up to +14V with a 1mA load current.
Thus, these parameters define an error band and take into account the worst case effects of voltage gain
and input impedance.
3. The response time specified is for a 100mV input step with 5mV overdrive.
