General Description

/ordering information 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.
