Working Principles

The SN74HCT373DBRG4 is an octal transparent latch that stores data when the latch enable (LE) signal is high. The stored data can be transferred to the outputs when the output enable (OE) signal is low. The latch operates on positive clock pulses (CP), capturing the data inputs (D0-D7) and holding them until the next clock pulse.

Detailed Application Field Plans

The SN74HCT373DBRG4 is commonly used in various digital applications, including but not limited to: - Data storage and transfer in microcontrollers - Address decoding in memory systems - Bus interfacing in communication protocols - Register-based operations in arithmetic circuits
