Working Principles

The 74ACT11373NSRE4 operates as an octal transparent latch with individual D-type flip-flop inputs. When the latch enable (LE) signal is high, the input data is transferred to the outputs. The output enable (OE) signal controls the state of the outputs, allowing bidirectional data flow when enabled.

The latch operates within a specified voltage range (2.0V to 5.5V) and has a propagation delay time of 6.5ns (typical). It is designed to provide high-speed operation, making it suitable for time-critical applications.

Detailed Application Field Plans

The 74ACT11373NSRE4 can be used in various digital logic applications, including but not limited to: - Data storage and retrieval systems - Address decoding circuits - Bus interface units - Multiplexers and demultiplexers - Register banks

Its high-speed operation, bidirectional data flow capability, and compatibility with different logic families make it a versatile choice for these applications.
