The MC14042BALD is a Quad Clocked D Latch manufactured by Freescale Semiconductor (now NXP). It is a CMOS integrated circuit consisting of four independent D-type latches. The state of each D input is transferred to the corresponding output when the clock input is high. When the clock input is low, the output retains the last state.

Applications:

• Data storage
• Sample-and-hold circuits
• Input/Output port expansion
• Register files
• Memory elements

Features:

• Quad D-Type Latches
• Independent Latch Enable (Clock) for Each Latch
• Wide Operating Voltage Range: 3.0V to 18V
• Low Power Consumption
• High Noise Immunity
• Standardized Symmetrical Output Characteristics

Benefits:

• Provides temporary storage of data.
• Versatile building block for digital systems.
• Low power consumption makes it suitable for battery powered applications.

Additional Details:

The MC14042BALD is available in a 16-pin DIP package. Each latch is independent, allowing for flexible data storage. The device utilizes CMOS technology, which provides high input impedance and excellent noise immunity. Data sheets are readily available for detailed specifications, timing diagrams, and application circuits. These latches can be cascaded for multi-bit storage applications. They are also commonly used in microprocessor systems for interface applications.
