14-stage divider and oscillator

Rev. 3 — 26 April 2018

Product data sheet

1 General description

74AHC1G4214 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

74AHC1G4214 counts up to 2¹⁴= 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.

2 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
