LM160/LM360 High Speed Differential Comparator General Description Features The LM160/LM360 is a very high speed differential input, complementary TTL output voltage comparator with improved characteristics over the A760/A760C, for which it is a pin-for-pin replacement. The device has been optimized for greater speed, input impedance and fan-out, and lower input offset voltage. Typically delay varies only 3 ns for overdrive variations of 5 mV to 400 mV. Complementary outputs having minimum skew are provided. Applications involve high speed analog to digital convertors and zero-crossing detectors in disk file systems. n n n n n n n n Guaranteed high speed: 20 ns 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 Connection Diagrams Metal Can Package Dual-In-Line Package DS005707-4 Order Number LM160H/883 (Note 1) See NS Package Number H08C DS005707-5 Order Number LM360M, LM360MX or LM360N See NS Package Number M08A or N08E Note 1: Also available in SMD# 5962-8767401 (c) 2000 National Semiconductor Corporation DS005707 www.national.com LM160/LM360 High Speed Differential Comparator August 2000 LM160/LM360 Absolute Maximum Ratings (Notes 6, 8) Storage Temperature Range -65C to +150C Lead Temperature (Soldering, 10 sec.) 260C Soldering Information Dual-In-Line Package Soldering (10 seconds) 260C Small Outline Package Vapor Phase (60 seconds) 215C Infrared (15 seconds) 220C See AN-450 "Surface Mounting Methods and Their Effect on Product Reliability" for other methods of soldering surface mount devices.
