High noise immunity: NIL = 30%, NIH = 30% of VCC at VCC = 5 V
وصف
The CD74HC574E 74HC574 are octal D-type flip-flops with 3-state outputs and the capability to drive 15 LSTTL loads. The eight edge-triggered flip-flops enter data into their registers on the LOW to HIGH transition of clock (CP). The output enable (OE) controls the 3-state outputs and is independent of the register operation. When OE is HIGH, the outputs are in the high-impedance state.
