MC14077BDR2G

Inverter Gates Overview

The MC14077BDR2G is a quad exclusive-NOR gate integrated circuit manufactured by onsemi, formerly Fairchild Semiconductor. It operates within a supply voltage range of 3V to 18V and features four independent two-input XNOR gates in a 14-pin SOIC package. The device supports low-level input voltages from 1.5V to 4V and high-level input voltages from 3.5V to 11V. It provides output currents of 8.8mA for both high and low states with a maximum quiescent current of 1µA. Propagation delay is specified at 110ns at 15V with a 50pF load. Operating temperatures range from -55°C to 125°C.

Inverter Gates Procurement Notes

Verify the manufacturer designation carefully as onsemi acquired Fairchild Semiconductor's operations. Confirm the specific suffix 'BDR2G' indicates the tape and reel packaging format suitable for automated surface-mount assembly. Ensure compliance with RoHS3 standards if required by your environmental regulations. Cross-reference the datasheet revision to confirm pinout and electrical characteristics match your design requirements before finalizing procurement.

Inverter Gates Selection Notes

Select this component when a compact solution for multiple XNOR functions is needed in surface-mount designs. The 14-SOIC package offers a balance between pin count and board space efficiency. Consider the propagation delay specifications against your system clock speeds to ensure timing margins are met. Verify that the input voltage levels align with your logic family drivers to guarantee reliable switching performance under all operating conditions.

Inverter Gates Part Context

This part belongs to the MC14000B series of CMOS logic devices, known for wide voltage operation and compatibility with various digital systems. The MC14077 specifically implements the XNOR function, which outputs true only when inputs are identical. This series is widely used in general-purpose digital applications where robustness and low power consumption are prioritized over high-speed switching capabilities found in advanced logic families.

Inverter Gates Replacement Considerations

The MC14077BDG serves as a tube-packaged alternative within the same functional family. Other MC14077 variants may exist but require verification of package type and electrical parameters. Ensure any substitute maintains the 14-SOIC footprint and compatible voltage ratings to avoid redesigning the PCB layout or power supply constraints.
