MC14515BCPG

Overview

The MC14515BCPG is a 4-to-16 line decoder manufactured by onsemi, belonging to the 4000B logic series. It features latched inputs and inverted (active-low) outputs, housed in a 24-pin PDIP package for through-hole mounting. The device operates on a single power supply ranging from 3 V to 18 V. It supports an operating temperature range of -55 °C to +125 °C. The internal circuitry utilizes N-channel and P-channel enhancement mode devices.

Feature Summary

• Features R-S type flip-flop latches that retain input data during strobe transitions
• Provides active-low decoded outputs for selected address lines
• Constructed with complementary CMOS technology for monolithic integration

Applications

• Memory address decoding systems
• Control signal routing in digital circuits
• Peripheral selection interfaces

Procurement Notes

Verify the specific suffix 'BCPG' against the manufacturer's current datasheet to confirm pinout compatibility and lead finish specifications. Confirm availability status as distribution records indicate this part may be discontinued or obsolete. Ensure the active-low output configuration aligns with system requirements before procurement.

Selection Notes

Select this component when a 4-bit latch with inverted outputs is required for address decoding. Compare with the MC14514BCPG if active-high outputs are needed instead. Verify that the 24-pin DIP package fits the target PCB layout constraints. Ensure the voltage supply remains within the specified 3 V to 18 V operational limits.

Part Context

This component is part of the standard 4000B CMOS logic family, known for wide voltage operation and high noise immunity. It serves as a specialized variant within the decoder category, distinguished by its integrated input latching capability which prevents glitches during address changes.

Replacement Considerations

The MC14514BCPG is the primary functional substitute, offering identical latching and decoding capabilities but with active-high outputs. Verify pin compatibility and output polarity requirements before substitution.
