LM6511

LM6511 180 ns 3V Comparator June 1999 LM6511 180 ns 3V Comparator General Description The LM6511 voltage comparator is ideal for analog-digital interface circuitry when only a +3V or +3.3V supply is available. The open-collector output permits signal compatibility with a wide variety of digital families: +5V CMOS, +3V CMOS, TTL and so on. Supply voltage may range from 2.7V to 36V between supply voltage leads. The LM6511 operates with little power consumption (Pdiss < 9.45 mW at V+ = +2.7V and V− = 0V). This voltage comparator offers many features that are available in traditional sub-microsecond comparators: output sync strobe, inputs and output may be isolated from system ground, and wire-ORing. Also, the LM6511 uses the industry-standard, single comparator pinout configuration. Features (Typical unless otherwise noted) n Operates at +2.7V, +3V, +3.3V, +5V n Low Power consumption < 9.45 mW @ V+ = 2.7V (max) n Fast Response Time of 180 ns Applications n Portable Equipment n Cellular Phones n Digital Level Shifting Connection Diagram 8-Pin SO DS011888-1 Ordering Information Package 8-Pin Small Outline Industrial Temperature Range −40˚C to +85˚C LM6511IM NSC Package Drawing M08A © 1999 National Semiconductor Corporation DS011888 www.national.com Absolute Maximum Ratings (Note 1) If Military/Aerospace specified devices are required, please contact the National Semiconductor Sales Office/ Distributors for availability and specifications.
