MC14514BCP

Overview

The MC14514BCP is a 4-bit transparent latch and 4-to-16 line decoder manufactured by onsemi. It features R-S type flip-flop latches that hold input data prior to the strobe transition from high to low. The device presents a logical '1' at the selected output, distinguishing it from active-low variants. Constructed with N-channel and P-channel enhancement mode devices in a single monolithic structure, it operates within a supply voltage range of 3.0 Vdc to 18 Vdc. It is capable of driving two low-power TTL loads or one low-power Schottky TTL load.

Feature Summary

• Combines 4-bit transparent latching with 4-to-16 line decoding functionality
• Active-high output logic for selected lines
• High noise immunity and low power dissipation characteristics
• Compatible with standard TTL logic loading requirements

Applications

• Decoding applications requiring low power dissipation
• Systems demanding high noise immunity
• Digital signal routing with latched address inputs

Procurement Notes

Verify the specific suffix 'CP' against the manufacturer's current package specifications to confirm pinout and physical dimensions. Ensure the component meets the required temperature range and that Pb-free packaging compliance aligns with project standards. Cross-reference the datasheet revision date to confirm electrical parameter consistency before integration into final designs.

Selection Notes

Select this part when an active-high decoded output is required alongside input latching capabilities. Compare against the MC14515B if active-low outputs are needed instead. Consider the operating voltage range and drive capability relative to downstream TTL loads. Verify package availability and thermal performance for the intended environmental conditions.

Part Context

This component belongs to the MC14514/MC14515 family of CMOS digital logic devices. It serves as a complementary counterpart to the active-low MC14515B variant. Both share identical internal architecture but differ in output polarity. The family is designed for general-purpose decoding and latching in battery-powered and noise-sensitive electronic systems.

Replacement Considerations

The MC14515B is the primary functional substitute within the same family, differing only in active-low output polarity. Other generic 4-to-16 decoders may require level shifting or logic inversion. Verify pin compatibility and output drive strength before substituting with non-family parts.
