• TSSOP package may be challenging to solder for inexperienced users.

Working Principles

The SN74ALVCH16374DL is a D-type flip-flop that stores and transfers digital data. It operates based on positive edge-triggered clock inputs. When the clock signal transitions from low to high, the data present at the D inputs is transferred to the Q outputs. The output enable (OE) input controls whether the outputs are active or in a high-impedance state. The master reset (MR) input resets all flip-flops to a known state when activated.

Detailed Application Field Plans

The SN74ALVCH16374DL is commonly used in various digital systems, including:

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

Its high-speed operation, low-voltage capability, and 3-state outputs make it suitable for applications requiring efficient data storage and transfer.
