GENERAL DESCRIPTION

The ADCMP604/ADCMP605 are very fast comparators fabricated on the Analog Devices, Inc. proprietary XFCB2 process. These comparators are exceptionally versatile and easy to use. Features include an input range from VEE − 0.5 V to VCCI + 0.2 V, low noise, LVDS-compatible output drivers, and TTL/CMOS latch inputs with adjustable hysteresis and/or shut-down inputs.
