MC14042BDR2

Latches Overview

The MC14042BDR2 is a quad transparent latch from the onsemi 4000B series, constructed with MOS P-channel and N-channel enhancement mode devices. It features four independent data inputs sharing a common clock line. The device supports a supply voltage range of 3.0 Vdc to 18 Vdc and operates within an ambient temperature range of -55°C to +125°C. Propagation delay times vary by voltage: at 5V, typical delay is 220 ns (max 440 ns); at 10V, typical is 90 ns (max 180 ns); at 15V, typical is 60 ns (max 120 ns).

Latches Feature Summary

• Features buffered data inputs and double diode input protection for signal integrity.
• Includes a polarity control input to reverse clock strobing between high and low levels.
• Provides both Q and Q complementary outputs for each latch channel.

Latches Applications

• Data storage in digital logic circuits requiring parallel-to-serial conversion.
• Interface buffering between different logic families such as CMOS and TTL.
• Timing control applications utilizing shared clock distribution.

Latches Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and compliance status. Ensure the procurement source provides valid RoHS material declarations. Confirm that the component matches the exact part number specifications before integration into production designs.

Latches Selection Notes

Latches FAQ

How does the polarity input affect data transfer?

When the polarity input is logic '0', data transfers during the low clock level. When it is logic '1', data transfers during the high clock level.

What is the maximum power dissipation per package?

The maximum power dissipation is 500 mW per package.
