Ratings based on +25 °C. APPLICATION NOTES RF input is AC coupled (DC block). DTCP20231 contains a plastic packaged IC-Ultra Hi-speed comparator. DTCP20231 provides maximum performance with minimum output capacitance. A heavy capacitive load slows down the TTL output response. Connect external threshold resistor from Rcntl port to ground.
