Working Principles

The 74AHCT373D,118 is an octal D-type transparent latch with 3-state outputs. It stores data based on the input signals received at the data inputs (D0-D7). The latch enable (LE) input controls when the data is latched and stored. The output enable (OE) input enables or disables the outputs (Q0-Q7) to drive external circuitry.

When the latch enable (LE) signal is active, the data inputs are transparently transferred to the outputs. When the latch enable (LE) signal is inactive, the outputs hold their previous state. The output enable (OE) signal determines whether the outputs are enabled (driving) or disabled (high impedance state).

Detailed Application Field Plans

The 74AHCT373D,118 can be used in various applications, including but not limited to: 1. Microprocessor-based systems 2. Data storage and retrieval systems 3. Address and data buses in digital systems 4. Communication systems 5. Industrial control systems
