Working Principles

M74HC73TTR operates as a dual 4-bit transparent latch. It latches the input data when the clock pulse (CP) signal transitions from low to high. The latch can be cleared using the clear (CLR) input or asynchronously reset using the master reset (MR) input. The outputs (Q0-Q3) reflect the state of the corresponding data inputs (D0-D3) when the latch is enabled by the clock pulse.

Detailed Application Field Plans

M74HC73TTR finds applications in various digital electronic circuits, including but not limited to: - Data storage systems - Address decoding - Multiplexing - Counters - Registers
