74AHC1G4212 12-stage divider and oscillator Product data sheet
●General description:
■74AHC1G4212 is a 12-stage divider and oscillator. It consists of a chain of 12 flip-flops. Each flip-flop divides the frequency of the previous flip-flop by two, consequently the 74AHC1G4212 counts up to 212 = 4096. 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 4096. 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.
●Features and benefits:
■Wide supply voltage range from 2.0 V to 5.5 V
■Overvoltage tolerant inputs to 5.5 V
■High noise immunity
■CMOS low power dissipation
■ESD protection:
▲HBM JESD22-A114F: exceeds 2000 V
▲CDM JESD22-C101E: exceeds 1000 V
■Latch-up performance exceeds 100 mA per JESD 78 Class II
■Specified from -40 °C to +85 °C and from -40 °C to +125 °C
