• Operating temperature range (-40°C to 85°C) may restrict usage in extreme environments

Working Principles

The SN74ALS374ADWRG4 is a D-type transparent latch that stores data on the rising edge of the clock signal. When the clock enable (CLK) input is high, the latch transfers the data from the input pins (D0-D7) to the corresponding output pins (Q0-Q7). The latch can be disabled by setting the output enable (OE) pin low, which puts all the outputs in a high-impedance state.

Detailed Application Field Plans

The SN74ALS374ADWRG4 is commonly used in various digital systems where data storage and synchronization are required. Some specific application fields include:

1. Microprocessors and microcontrollers
2. Data communication systems
3. Memory modules
4. Industrial automation
5. Automotive electronics
