KA319

www.fairchildsemi.com KA319 Dual Comparator Features Operates from a single 5V supply Typically 80ns response time at ±15V Open collector outputs : up to + 35V High output drive current : 25mA Inputs and outputs can be isolated from system ground Minimum fan-out of 2 (each side) Two independent comparators Description The KA319 is a dual high speed voltage comparator designed to operate from a single + 5V supply up to ±15V dual supplies. Open collector of the output stage makes the KA319 compatible with RTL, DTL and TTL as well as capable of driving lamps and relays at currents up to 25mA. Typical response time of 80ns with ±15V power supplies makes the KA319 ideal for application in fast A/D converts, level shifters, oscillators, and multivibrators. 14-DIP 1 14-SOP 1 Internal Block Diagram Rev. 1.0.2 ©2001 Fairchild Semiconductor Corporation KA319 Schematic Diagram Absolute Maximum Ratings Parameter Supply Voltage Output to Negative Supply Voltage Ground to Negative Supply Voltage Ground to Positive Supply Voltage Differential Input Voltage Input Voltage Output Short Circuit Duration Power Dissipation Operating Temperature Range KA319 Storage Temperature Range Symbol VCC VO - VEE VEE VCC VI(DIFF) VI PD TOPR TSTG Value 36 36 25 18 5 ±15 10 500 0 ~ + 70 -65 ~ + 150 Unit V V V V V V sec mW °C °C 2 KA319 Electrical Characteristics (VCC = +15V, VEE = -15V, TA = 25°C, unless otherwise specified) Parameter Input Offset Voltage (Note 1) Input Offset Curre...
