Dual Comparator
Operates from single supply Typically 80ns response time ±15V Open collector outputs High output drive current 25mA Inputs outputs isolated from system ground Minimum fan-out (each side) independent comparators
Description
LM319 dual high speed voltage comparator designed operate from single supply ±15V dual supplies. Open collector output stage makes LM319 compatible with RTL, well capable driving lamps relays currents 25mA. Typical response time 80ns with ±15V power supplies makes LM319 ideal application fast converts, level shifters, oscillators, multivibrators.
