74AHC1G4214-Q100 14-stage divider and oscillator Rev. 2 13 January 2022 Product data sheet 1. General description 74AHC1G4214-Q100 is a 14-stage divider and oscillator. It consists of a chain of 14 flip-flops. Each flip-flop divides the frequency of the previous flip-flop by two, consequently the 14 74AHC1G4214-Q100 counts up to 2 = 16384. 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 16384.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. 2. Features and benefits Automotive product qualification in accordance with AEC-Q100 (Grade 1) Specified from -40 C to +85 C and from -40 C to +125 C 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: MIL-STD-883, method 3015 exceeds 2000 V HBM JESD22-A114F: exceeds 2000 V CDM JESD22-C101E: exceeds 1000 V Latch-up performance exceeds 100 mA per JESD 78 Class II 3.
