Provldes frequency response from 0 to 1 MHz at very low power levels, as required fordriving CMOS logic of frequency counter. Diodes protect input from overload. Output impedance of frequency source should be kept below 50K to minimize noise pickup.-R. Tenny, Counter Pre-Amp Matches CMOS Logic Capability, EDN Magazine, Sept. 20, 1976, p 114 and 116.
