MC14551BFEL

Analog Switches, Multiplexers, Demultiplexers Overview

The MC14551BFEL is a quad bilateral analog switch manufactured by onsemi, housed in a 16-SOEIAJ surface-mount package. It operates as a 2:1 multiplexer/demultiplexer with four independent SPDT circuits. The device supports a supply voltage range of 3V to 18V and draws a maximum supply current of 10 µA. Key electrical characteristics include a maximum on-resistance of 280 ohms, a channel-to-channel matching tolerance of 10 ohms, and an off-state leakage current of 100 nA. It features a -3dB bandwidth of 17 MHz and low channel capacitance of 5 pF. The component functions reliably across an extended temperature range from -55°C to 125°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

This part number is officially obsolete and no longer manufactured by onsemi. Verification of availability requires checking authorized distributors for remaining stock or approved replacement components. Ensure that any substitute devices meet the original pinout and electrical specifications to maintain system compatibility without redesign.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Designers should verify that the required on-resistance and bandwidth specifications are met by available alternatives, as the MC14551BFEL is discontinued. Consider the operating temperature range and supply voltage requirements when selecting a replacement. Confirm that the substitute package matches the 16-SOEIAJ footprint if board space is constrained.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MC14551BFEL belongs to the MC14551B family of CMOS analog switches. This series is designed for general-purpose signal switching applications requiring low power consumption and high isolation. The BFEL suffix indicates a specific tape-and-reel packaging configuration for automated assembly processes.
