MC14514BCPG

Overview

The MC14514BCPG is a CMOS logic integrated circuit belonging to the 4000B series, manufactured by onsemi. It functions as a 4-bit transparent latch and a 4-to-16 line decoder with latched inputs. The device features R-S type flip-flops that hold input data prior to a strobe transition from high to low. It operates within a supply voltage range of 3 V to 18 V and supports an operating temperature range from -55 °C to +125 °C. The component is housed in a 14-pin PDIP package.

Feature Summary

• Integrates a 4-bit transparent latch with a 4-to-16 line decoder for simultaneous data storage and decoding.
• Utilizes R-S type flip-flops to maintain input state until the strobe signal transitions from logical high to low.
• Constructed using N-channel and P-channel enhancement mode devices for low power dissipation and high noise immunity.

Applications

• Decoding applications requiring low power dissipation
• Systems demanding high noise immunity
• Driving two low-power TTL loads or one low-power Schottky TTL load

Procurement Notes

Verify the specific suffix 'CPG' confirms the PDIP package and lead-free status against the official datasheet. Confirm the active status and availability directly with onsemi or authorized distributors, as component lifecycle states can change. Ensure the required operating temperature range aligns with your system specifications before procurement.

Selection Notes

Select this component when a combined latch and decoder function is required in a single package. It is suitable for designs needing to drive standard TTL loads while maintaining CMOS input characteristics. Consider the 14-pin PDIP form factor for through-hole assembly requirements. Verify compatibility with the 3 V to 18 V supply voltage range of the target application.

Part Context

This part belongs to the MC14514/MC14515 family of 4-bit latch/decoders. The MC14514B variant specifically provides active-high outputs, whereas the complementary MC14515B offers active-low outputs. Both share identical internal latch structures but differ in output polarity. The MC14514BCPG represents the commercial grade version in a plastic dual in-line package.

Replacement Considerations

MC14515BCPG: Identical functionality but with active-low outputs instead of active-high. CD4514BM: Pin-compatible alternative from Texas Instruments offering the same 4-bit latch and 4-to-16 decoder features.
