Part Number : HD74HC564P
Function : Octal D-type Flip-Flops (with 3-state outputs)
Package : DIP 20 Pin type
Maker : Renesas Electronics
Pinouts : 
Description :
These devices are positive edge triggered flip-flops. The difference between HD74HC564, HD74HC564P and HD74HC574 is only that the former has inverting outputs and the latter has noninvertering outputs.
Data at the D inputs, meeting the set-up and hold time requirements, are transferred to the Q or outputs on positive going transitions of the clock (CK) input. When a high logic level is applied to the output control (OC) input, all outputs go to a high impedance state, regardless of what signals are present at the other inputs and the state of the storage elements.
Features
• High Speed Operation: tpd (Clock to Output) = 13 ns typ (CL = 50 pF)
• High Output Current: Fanout of 15 LSTTL Loads
• Wide Operating Voltage: VCC = 2 to 6 V
• Low Input Current: 1 μA max
