74HC574

The 74HC574 is designed as high-speed si-gate CMOS devices and are pin compatible with low power schottky TTL (LSTTL). It is specified in compliance with JEDEC standard no. 7A. It is octal D-type flip-flops 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 six features of the 74HC574. The first one is 3-state non-inverting outputs for bus oriented applications. The second one is 8-bit positive edge-triggered register. The third one is common 3-state output enable input. The fourth one is independent register and 3-state buffer operation. The fifth one is its output capability would be bus driver. The sixth one is its ICC category would be MSI. That are all the main features.

Some important AC characteristics and specifications of the 74HC574 have been concluded into several points as follow.For Tamb=25°C the first one is about its propagation delay CP to Qn which would be typ 47ns and max 150ns at Vcc=2.0V and would be typ 17ns and max 30ns at Vcc=4.5V and would be typ 14ns and max 26ns at Vcc=6.0V. The second one is about its 3-state output enable time OE to Qn which would be typ 44ns and max 140ns at Vcc=2.0V and typ 16ns and max 28ns at Vcc=4.5V and would be typ 13ns and max 24ns at Vcc=6.0V. The third one is about its 3-state output disable time OE to Qn which would be typ 39ns and max 125ns at Vcc=2.0V and typ 14ns and max 25ns at Vcc=4.5V and would be typ 11ns and max 21ns at Vcc=6.0V. The fourth one is about its output transition time which would be typ 14ns and max 60ns at Vcc=2.0V and typ 5ns and max 12ns at Vcc=4.5V and would be typ 4ns and max 10ns at Vcc=6.0V. And so on.
