Single/Dual/Quad, Ultra-High-Speed, +3V/+5V,
Beyond-the-Rails Comparators
_________________General Description
____________________________Features
♦ Ultra-Fast, 4.5ns Propagation Delay
The MAX961–MAX964/MAX997/MAX999 are low-power,
ultra-high-speed comparators with internal hysteresis.
These devices are optimized for single +3V or +5V
operation. The input common-mode range extends
♦ Ideal for +3V and +5V Single-Supply Applications
♦ Beyond-the-Rails Input Voltage Range
♦ Low, 5mA Supply Current (MAX997/MAX999)
♦ 3.5mV Internal Hysteresis for Clean Switching
♦ Output Latch (MAX961/MAX963)
™
100mV Beyond-the-Rails , and the outputs can sink
or source 4mA to within 0.52V of GND and V
.
CC
Propagation delay is 4.5ns (5mV overdrive), while sup-
ply current is 5mA per comparator.
The MAX961/MAX963/MAX964 and MAX997 have a
shutdown mode in which they consume only 270µA
supply current per comparator. The MAX961/MAX963
provide complementary outputs and a latch-enable fea-
ture. Latch enable allows the user to hold a valid com-
parator output. The MAX999 is available in a tiny
SOT23-5 package. The single MAX961/MAX997 and
dual MAX962 are available in space-saving 8-pin
♦ TTL/CMOS-Compatible Outputs
♦ 270µA Shutdown Current per Comparator
(MAX961/MAX963/MAX964/MAX997)
