The SN74HC574N, SN74HCT574, SN74LS574N, SN74574 Are 8-bit positive-edge triggered D-type flip-flop with 3-state outputs. The device features a clock (CP) and output enable (OE) inputs.
The CD4515BE is consist of a 4-bit strobed latch and a 4-to-16-line decoder. The latches hold the last input data presented prior to the strobe transition from 1 to 0. Inhibit control allows all outputs to be placed at 1 regardless of the state of the dat
