MC14512BDR2G

Overview

The MC14512BDR2G is an 8-channel data selector and multiplexer manufactured by onsemi. It operates within a supply voltage range of 3V to 18V and features a single circuit configuration with 1 x 8:1 functionality. The device utilizes a 16-SOIC surface-mount package, measuring 0.154 inches (3.90mm) in width. It supports high-level and low-level output currents of 8.8mA each. The component is designed for operation across an extended temperature range from -55°C to +125°C and complies with RoHS3 standards.

Feature Summary

• Provides 8-channel data selection and multiplexing capabilities via three address inputs.
• Features a tri-state output controlled by an enable input for bus interfacing.
• Includes an inhibit function that forces the output into a high-impedance state.

Applications

• Data routing in digital communication systems
• Signal selection in measurement instrumentation
• Address decoding in microprocessor-based systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct packaging and tape-and-reel specifications. Confirm compliance requirements such as RoHS3 status and moisture sensitivity level prior to procurement. Cross-reference the part number with official distributor catalogs to validate availability and lead times. Ensure the selected variant matches the required operating temperature range and package dimensions for your PCB layout.

Selection Notes

Select this component when an 8-to-1 multiplexer with tri-state outputs is required in CMOS logic applications. Consider the 3V to 18V supply range compatibility with your system voltage. Evaluate the 16-SOIC package constraints against your board space limitations. Verify that the 8.8mA output drive capability meets the load requirements of the downstream circuitry.

Part Context

This part belongs to the MC14512 family of 8-channel data selectors. It is part of onsemi's broader portfolio of CMOS logic devices designed for general-purpose digital applications. The device shares functional similarities with other multiplexers but offers specific pinout and electrical characteristics defined by the 4000B series standards.

Replacement Considerations

Check for direct pin-compatible alternatives within the MC14512 family or equivalent 8-channel multiplexers from other manufacturers. Verify that any substitute maintains the same supply voltage range, output current capabilities, and package dimensions. Ensure logical functionality and pin assignments match exactly to avoid redesign efforts.
