Description

The SN74HCS574 contains eight D-type flip-flops. All inputs include Schmitt-trigger architecture. All channels share a rising edge triggered clock (CLK) input and active low output enable (OE) input. This device has a flow-through pinout which allows for easier bus routing. The SN74HCS574 contains eight D-type flip-flops. All inputs include Schmitt-trigger architecture.
