HIGH SPEED DUAL BIPOLAR COMPARATORS
LM119 - LM219
LM319
HIGH SPEED DUAL COMPARATORS
. TYPICALLY 80ns RESPONSE TIME AT ± 15V
. MAXIMUM INPUT CURRENT OF 1 m A OVER
. INPUTS AND OUTPUTS CAN BE ISOLATED
FROM SYSTEM GROUND
OPERATING TEMPERATURE RANGE
. HIGH COMMON-MODE SLEW RATE
DESCRIPTION
These products are precision high speed dual
comparators designed to operate over a 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.
Although designed primarily for applications
requiring operation from digital logic supplies, are
fully specified for power supplies up to ± 15V.
They feature faster response than the LM111 at the
expense of higher power dissipation. However, the
high speed, wide operating voltage range and low
package count make the much more versatile.

Notes : 1. For supply voltages less than
15V the absolute maximum input voltage is equal to the supply volt age.
2. These specifications apply for V CC = ± 15V, unless otherwise stated. The offset voltage, offset current and
bias current specifications apply for any supply volt age 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 wit h 5mV overdrive.
