MC14042BCPG

Latches Overview

The MC14042BCPG is a quad transparent latch from the onsemi 4000 series, housed in a 16-pin PDIP package. It features four independent data inputs sharing a common clock and polarity control input. The device operates within a supply voltage range of 3.0 Vdc to 18.0 Vdc and supports an ambient temperature range of -55 °C to +125 °C. It provides both Q and Q outputs for each latch stage.

Latches Feature Summary

• Quad transparent latch architecture with buffered data inputs
• Common clock input with polarity control for strobing direction
• Double diode input protection against high static voltages
• Capable of driving low-power TTL or Schottky TTL loads

Latches Applications

• Data storage and buffering in digital logic circuits
• Interface between different logic families
• Timing signal latching applications

Latches Procurement Notes

Verify the component marking matches MC14042BCP or MC14042BCPG to confirm the manufacturer and lead-free status. Ensure the package type corresponds to the required PCB footprint. Confirm that the operating environment stays within the specified voltage and temperature limits to maintain reliability.

Latches Selection Notes

Select this component when a multi-bit parallel data storage solution is needed with flexible clocking options. The polarity control feature allows adaptation to system timing requirements without additional logic. Consider the wide supply voltage range for compatibility with various power rails.

Latches Part Context

This part belongs to the MC14042B family of quad transparent latches manufactured by onsemi. It is designed using MOS enhancement mode devices in a monolithic structure. The device is part of the standard 4000 series logic family, offering broad industry compatibility.

Latches Replacement Considerations

Compatible substitutes include MC14042BD (SOIC-16) and MC14042BFEL (SOEIAJ-16). Verify pinout compatibility and package dimensions before substitution.
