Key Features
- 8:1 single-channel multiplexing with 3-bit select input routes one of 8 digital inputs to the output in standard 4000-series CMOS logic
- Wide 3 V to 15 V supply range enables use in both 5 V TTL-compatible and 12 V industrial control systems without redesign
- 16-pin SOIC package with 50 pF load drive capability suits PCB designs requiring compact data-routing logic with low standby current
Applications
CD4512BM is used in data routing, bus switching, and signal selection circuits where one of 8 digital sources must be connected to a single output under microcontroller or logic control. It suits industrial PLCs, test equipment multiplexers, and legacy 4000-series CMOS redesigns that need a 3 V to 15 V tolerant 8:1 selector in a compact SOIC-16 package. The device also serves audio and digital communication boards where channel selection across 8 inputs with low standby current is required.

Frequently Asked Questions
Over what supply voltage range does CD4512BM operate, and how many inputs can it select from?
CD4512BM operates from 3 V to 15 V supply voltage and can select any one of 8 digital inputs using a 3-bit binary address, with a dedicated enable pin that tri-states the output when deasserted, making it compatible with both 5 V TTL logic systems and 12 V industrial controllers.
How does CD4512BM's enable input improve bus multiplexing in a multi-board industrial design?
The active-high enable pin on CD4512BM places the output in a high-impedance state when deasserted, allowing multiple CD4512BM devices to share a common output bus without contention; each device drives the bus only when its enable is high, supporting up to 64 inputs multiplexed onto 1 wire with 8 cascaded ICs at supply voltages up to 15 V.
For a legacy 4000-series CMOS redesign, what board space does the CD4512BM SOIC-16 package occupy?
The SOIC-16 package of CD4512BM measures approximately 9.9 mm × 3.9 mm with a 1.27 mm pitch, which is about 60% smaller than the equivalent DIP-16 package at 19.3 mm × 6.35 mm, allowing engineers to shrink legacy 4000-series designs significantly while retaining full 3 V to 15 V supply compatibility and 50 pF output drive capability.
