74HC374 8 D-Flip-Flop With 3-Output State IC (74374 IC) DIP-20 Package R385 while nickel coating protects the74HC series ICs are High speed logic gates with very low power consumption that utilize advanced silicon gate CMOS technology and 74HC374 is one of them. 74HC374 ICs contain eight positive edge triggered D type flip flops with 3 Output states i. e. High, Low, and High Impedance. Which is designed specifically for driving highly capacitive or relatively low impedance loads. High Impedance comes to active low enable pin of these ICs where output enable
