1. General description

74AHC1G4215 is a 15-stage divider and oscillator. It consists of a chain of 15 flip-flops. Each

flip-flop divides the frequency of the previous flip-flop by two, consequently the 74AHC1G4215

counts up to 215 = 32768. The single inverting stage (X1 to X2) functions as a crystal oscillator

or an input buffer for an external oscillator. When used as a buffer the output X2 should be left

floating. The frequency of the output (Q) is the frequency applied to X1 divided by 32768.The

divider advances on the negative-going transition of X1.

The X1 input is overvoltage tolerant. This feature allows the use of this device as a voltage level

translator in mixed voltage environments.
