KA319D

www.fairchildsemi.com KA319 Dual Comparator Features 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 shiftiers, oscillators, and multivibrators. 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 14-DIP 1 14-SOP 1 Internal Block Diagram NC 1 14 NC NC 2 13 NC GND1 3 IN (+) 4 IN (-) 5 VEE 6 OUTPUT2 7 12 OUTPUT1 11 VCC + _ _ 10 IN2 (-) + 9 IN2 (+) 8 GND2 Rev. 1.0.3 ©2012 Fairchild Semiconductor Corporation KA319 Schematic Diagram R1 VCC R3 R2 R7 R6 Q4 Q9 Q8 Q3 Q7 IN (-) Q2 R4 IN (+) R12 Q6 C1 R5 Q1 R8 Q5 Q15 R15 Q10 OUTPUT Q14 R18 R13 R20 R23 Q21 Q13 R9 R22 Q22 R11 R10 Q16 Q11 R19 Q20 Q12 R16 R14 Q19 R25 R24 Q18 Q17 R21 R17 GND VEE Absolute Maximum Ratings Parameter Symbol Value Unit VCC 36 V Output to Negative Supply Voltage VO - VEE 36 V Ground to Negative Supply Voltage VEE 25 V Ground to Positive Supply Voltage VCC 18 V VI(DIFF) 5 V VI ±15 V Supply Voltage Differential Input Voltage Input Voltage Output Short Circuit Duration - 10 sec PD 500 mW Thermal Resistance Junction-Ambient Max.

The offset voltage and offset currents given are the maximum values required to drive the output within a volt of either supply with a 1mA load. Thus, these parameters define an error band and take into account the worst case effects of voltage gain and input impedance. 2. The response time specified is for a 100mV input step with 5mV overdrive. 3. KA319 : 0 ≤ TA ≤ +70°C 3 KA319 Typical Performance Characteristics 4 Figure 1. Input Current Figure 2.
