MAX961MAX964/MAX997/MAX999 19-1129 Rev 4 3/99 Single/Dual/Quad, Ultra-High-Speed, +3V/+5V, Beyond-the-Rails Comparators General Description Features The MAX961MAX964/MAX997/MAX999 are low-power, Ultra-Fast, 4.5ns Propagation Delay ultra-high-speed comparators with internal hysteresis. Ideal for +3V and +5V Single-Supply Applications These devices are optimized for single +3V or +5V operation. The input common-mode range extends Beyond-the-Rails Input Voltage Range 100mV Beyond-the-Rails , and the outputs can sink Low, 5mA Supply Current (MAX997/MAX999) or source 4mA to within 0.52V of GND and V . CC Propagation delay is 4.5ns (5mV overdrive), while sup- 3.5mV Internal Hysteresis for Clean Switching ply current is 5mA per comparator. Output Latch (MAX961/MAX963) The MAX961/MAX963/MAX964 and MAX997 have a shutdown mode in which they consume only 270A TTL/CMOS-Compatible Outputs supply current per comparator. The MAX961/MAX963 270A Shutdown Current per Comparator provide complementary outputs and a latch-enable fea- (MAX961/MAX963/MAX964/MAX997) ture. Latch enable allows the user to hold a valid com- parator output. The MAX999 is available in a tiny Available in Space-Saving Packages: SOT23-5 package. The single MAX961/MAX997 and 5-Pin SOT23 (MAX999) dual MAX962 are available in space-saving 8-pin MAX 8-Pin MAX (MAX961/MAX962/MAX997) packages. 16-Pin QSOP (MAX964) Applications Ordering Information Single 3V/5V Systems PIN- SOT Portable/Battery-Powered Systems PART TEMP RANGE PACKAGE TOP MARK Threshold Detectors/Discriminators MAX961ESA -40C to +85C 8 SO GPS Receivers MAX961EUA -40C to +85C 8 MAX MAX962ESA -40C to +85C 8 SO Line Receivers MAX962EUA -40C to +85C 8 MAX Zero-Crossing Detectors MAX963ESD -40C to +85C 14 SO High-Speed Sampling Circuits MAX964ESE -40C to +85C 16 Narrow SO MAX964EEE -40C to +85C 16 QSOP MAX997ESA -40C to +85C 8 SO Selector Guide MAX997EUA -40C to +85C 8 MAX MAX999EUK-T -40C to +85C 5 SOT23-5 ACAB Pin Configurations TOP VIEW Q15 V CC MAX961 1 Yes Yes Yes 8 SO/MAX MAX999 2 GND MAX962 2 No No No 8 SO/MAX MAX963 2 Yes Yes Yes 14 SO IN+34 IN- MAX964 4 No Yes No 16 SO/QSOP MAX997 1 No Yes No 8 SO/MAX SOT23-5 MAX999 1 No No No 5 SOT23 Beyond-the-Rails is a trademark of Maxim Integrated Products, Inc.
