Intersil 7207 IC generates clock and housekeeping pulses required for frequency counter. With pin 11 grounded, gate output is high for 0.1 s and low for 0.1 s. With pin 11 high, gate is high 0.01 s and low 0.01 s.1.6-kHz square wave at pin 12 is useful for multiplexing displays. Update output is narrow negative-going pulse coincident with rising edge of gate output, for use in transferring countto display latches. Reset outputis used to reset counter.-D.
