Tri-State Buffer ICs
Series
117
1
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.
