HD74HCT574 - Octal D-type Flip-Flops (with 3-state outputs)
These devices are positive edge triggered flip-flops.
The difference between HD74HCT564 and HD74HCT574 is only that the former has inverting outputs and the latter has non-inverting outputs.
Data at the D inputs, meeting the set-up and hold time requirements, are transferred to the Q or Q outputs on
HD74HCT574 Features
* LSTTL Output Logic Level Compatibility as well as CMOS Output Compatibility High Speed Operation: tpd (D to Q, Q) = 15 ns typ (CL = 50 pF) High Output Current: Fanout of 15 LSTTL Loads Wide Operating Voltage: VCC = 4.5 to 5.5 V Low Input Cu
