LM319M

www.fairchildsemi.com LM319 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 LM319 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 LM319 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 LM319 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 LM319 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 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 LM319 Electrical Characteristics (VCC = + 15V, VEE = - 15V, TA = 25°C, unless otherwise specified) Parameter Input Offset Voltage (Note 1) Input Offset Current (Note 1) Input Bias Current Voltage Gain Response Time (Note 2) Saturation Voltage Symbol VIO IIO IBIAS GV TRES VSAT VCC = ±15V VCC=15V, VEE = -15V , VI ≤ -5mV, IO = 25mA VCC = 4.5V,VEE = 0V VI ≤ -10mV, IO ≤ 3.2mA VI ≥ 5mV, VO(P) = 35V VI ≥ 10mV, VO(P) = 35V Input Voltage Range Differential Input Voltage Positive Supply Current Positive Supply Current Negative Supply Current VI(R) VI(DIFF) ICC1 ICC2 IEE VCC = 5V, VEE = 0V VCC = ±15V VCC = ±15V Note 3 VCC = ±15V VCC = 5V, VEE = 0V Note3 R S ≤ 5K Ω Conditions LM319 Min.

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. LM319 : 0 ≤ TA ≤ +70°C 3 LM319 Typical Performance Characteristics Figure 1. Input Current Figure 2.
