Working Principles

The SN74ALS874BNSRE4 is an 8-bit D-type flip-flop with 3-state outputs. It operates synchronously with a common clock pulse input (CP). The data inputs (D0-D7) are latched into the flip-flops on the rising edge of the clock pulse. The clear input (CLR) is asynchronous and active LOW, allowing for the clearing of all flip-flops when activated. The output enable input (OE) is active LOW and controls the 3-state outputs (Q0-Q7), enabling or disabling their functionality.
