3 Description

The SN74LV8T574-EP devices are octal edgetriggered

D-type flip-flops.

These devices feature 3-state outputs designed

specifically for driving highly capacitive or relatively

low-impedance loads. The devices are particularly

suitable for implementing buffer registers, I/O ports,

bidirectional bus drivers, and working registers.

On the positive transition of the clock (CLK) input, the

Q outputs are set to the logic levels set up at the data

(D) inputs.
