MC14049BDR2G

Inverter Gates Overview

The MC14049BDR2G is a hex inverting buffer and line driver from the onsemi 4000 series CMOS logic family. It features six independent inverting channels housed in a 16-lead SOIC surface-mount package. The device operates within a supply voltage range of 3 V to 18 V, supporting wide input voltage levels that can exceed the positive supply rail. Key electrical parameters include a maximum low-level output current of 30 mA and a high-level output current of -4.7 mA. Propagation delay varies with supply voltage, specified at 140 ns at 5 V, 80 ns at 10 V, and 60 ns at 15 V. The component supports an operating temperature range from -55°C to +125°C.

Inverter Gates Feature Summary

• Provides six independent inverting buffer channels for signal inversion and buffering.
• Accepts input voltages exceeding the positive supply voltage (VCC), enabling direct logic level translation between different voltage domains.
• Capable of driving two Low-power TTL loads or one Low-power Schottky TTL load directly over the rated temperature range.
• Features diode protection on all inputs to safeguard against transient voltage events.

Inverter Gates Applications

• Converting COS/MOS logic signals to DTL/TTL logic levels.
• Driving digital displays and indicator loads.
• Waveform shaping and irregular digital signal conditioning.
• General-purpose signal buffering in mixed-voltage systems.

Inverter Gates Procurement Notes

Verify the specific suffix 'DR2G' corresponds to the SOIC-16 tape-and-reel packaging configuration. Confirm RoHS compliance status as indicated by the 'G' suffix in procurement records. Ensure the ordering part number matches the exact manufacturer designation to avoid pinout or electrical specification mismatches during integration.

Inverter Gates Selection Notes

Select this component when hex inverting functionality is required alongside the ability to handle input voltages higher than the system's VCC rail. It is suitable for applications requiring moderate drive strength (30 mA sink) and wide temperature operation. Consider alternative packages if through-hole mounting is preferred, or other logic families if faster propagation speeds are necessary.

Inverter Gates Part Context

This device belongs to the standard 4000 series CMOS logic family, known for wide supply voltage ranges and high noise immunity. The MC14049B variant specifically provides inverting buffers, distinguishing it from non-inverting counterparts like the CD4049. It serves as a foundational building block for digital interface circuits requiring signal inversion and level shifting capabilities.

Inverter Gates Replacement Considerations

The MC14049BDR2G is a pin-for-pin replacement for the CD4049B. Verify compatibility with HEF4049BT equivalents if sourcing from different manufacturers. Ensure substitute parts maintain the same SOIC-16 footprint and electrical characteristics regarding input voltage tolerance and output drive capability.
