Product Summary
The 74HC574D is a high-speed Si-gate CMOS device and is pin compatible with low power Schottky TTL (LSTTL). It is specified in compliance with JEDEC standard no. 7A. The 74HC574D is a octal D-type flip-flop featuring separate D-type inputs for each flip-flop and non-inverting 3-state outputs for bus oriented applications. A clock (CP) and an output enable (OE) input are common to all flip-flops. The 8 flip-flops will store the state of their individual D-inputs that meet the set-up and hold time requirements on the LOW-to-HIGH CP transition. When OE is LOW, the contents of the 8 flip-flops are available at the outputs.
Parametrics
74HC574D absolute maximum ratings: (1)tPHL/ tPLH propagation delay CP to Qn CL = 15 pF; VCC=5 V: 14ns; (2)fmax maximum clock frequency: 123MHz; (3)CI input capacitance: 3.5pF; (4)CPD power dissipation capacitance per flip-flop: 22 pF.
