Description

General part information

CD74HCT574-EP Series

The CD74HCT574 is an octal D-type flip-flop 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 the 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.
