LM160QML LM160QML High Speed Differential Comparator Literature Number: SNOSAR0 LM160QML High Speed Differential Comparator General Description Features The LM160 is a very high speed differential input, complementary TTL output voltage comparator with improved characteristics over the μA760/μA760C, for which it is a pin-forpin replacement. The device has been optimized for greater speed, input impedance and fan-out, and lower input offset voltage. Typically delay varies only 3nS for overdrive variations of 5mV to 400mV. Complementary outputs having minimum skew are provided. Applications involve high speed analog to digital convertors and zero-crossing detectors in disk file systems. ■ ■ ■ ■ ■ ■ ■ ■ Guaranteed high speed: 20nS max Tight delay matching on both outputs Complementary TTL outputs High input impedance Low speed variation with overdrive variation Fan-out of 4 Low input offset voltage Series 74 TTL compatible Ordering Information NS Part Number SMD Part Number NS Package Number Package Description LM160H/883 5962–8767401GA H08C 8LD Metal Can (Note 1) Bare Die LM160 MD8 Note 1: FOR ADDITIONAL DIE INFORMATION, PLEASE VISIT THE HI REL WEB SITE AT: www.national.com/analog/space/level_die Connection Diagrams Metal Can Package 20155904 See NS Package Number H08C © 2010 National Semiconductor Corporation 201559 www.national.com LM160QML High Speed Differential Comparator November 30, 2010 LM160QML Schematic Diagram 20155901 www.national.com 2 LM160QML Absolute Maximum Ratings (Note 2) Positive Supply Voltage Negative Supply Voltage Peak Output Current Differential Input Voltage Input Voltage +8V −8V 20 mA ±5V V+ ≥ VI ≥ V− −55°C ≤ TA ≤ +125°C Operating Temperature Range −65°C ≤ TA ≤ +150°C Storage Temperature Range Thermal Resistance θJA Still Air 400 LF/min 165°C/W 67°C/W 25°C/W θJC Lead Temperature (Soldering, 10 sec.)
