XC2301 Series
ETR1409_001a
Tri-State Buffer ICs
GENERAL DESCRIPTIO N
The 2301 series are a group of high frequency, CMOS low power tri-state buffer ICs with input amplifier, divider and output
tri-state buffer circuits built-in.
Output can be selected from any one of the following values for fin (input frequency) : fin/1, fin/2, fin/4, fin/8.
The series is available in an ultra small SOT-26 package.
