Functional Features

• Quad D-type latch: HCF4042BEY consists of four independent D-type latches, allowing for simultaneous storage and retrieval of data.
• 3-state outputs: The IC offers three output states - high, low, and high impedance, providing flexibility in connecting multiple devices.
• Output Enable (/OE): The /OE pin enables or disables the outputs, allowing for efficient control of data flow.
• Clear (/CLR) input: The /CLR pin resets all latch outputs to a known state, facilitating system initialization.
• Parallel Load (/PL) input: The /PL pin loads the data present at the D1-D4 inputs into the latches when activated.

Advantages and Disadvantages

Advantages

• Versatile functionality with quad D-type latches.
• Wide operating voltage range.
• High noise immunity.
• Low power consumption.
• Compact package for easy integration.

Disadvantages

Working Principles

HCF4042BEY operates based on the principles of digital logic. Each D-type latch stores a single bit of information. When the /PL input is activated, the data present at the D1-D4 inputs is loaded into the corresponding latches. The stored data can be retrieved from the Q1-Q4 outputs. The /OE pin controls the output enable/disable state, while the /CLR input resets all latch outputs.
