74HC574 (DIP-20) High-Speed CMOS Octal D-Type Flip-Flop - (AD4521)

Description:

The HC374, HCT374, HC574, and HCT574 are octal D-type flip-flops with 3-state outputs capable of driving 15 LSTTL loads. The eight edge-triggered flip-flops enter data into their registers during 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 a high impedance state. The 374 and 574 have identical functions and differ only in their pin configuration.
