1. General description

74AHC1G4215-Q100 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-Q100 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.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100

(Grade 1) and is suitable for use in automotive applications.
