TC4049BF-ELNF

Inverter Gates Overview

The TC4049BF-ELNF is a hex buffer/converter (inverting type) from the Toshiba 4000B series. It operates on a DC supply voltage of 3V to 18V with an operating temperature range of -40°C to 85°C. The device features six independent inverting circuits, each with one input and push-pull output. It provides high-level output currents up to 28mA at 15V and low-level output currents up to 48mA at 15V. Propagation delay times range from 15ns to 60ns depending on the supply voltage.

Inverter Gates Feature Summary

• Inverts logic signals using a three-stage inverter circuit design for ideal switching characteristics.
• Accepts input voltages up to VSS + 18V regardless of the supply voltage level.
• Capable of directly driving TTL or DTL loads due to large output current capability.
• Functions as a level converter between different CMOS/TTL logical systems.

Inverter Gates Applications

• Interfacing from CMOS to TTL or DTL logic families
• Converting 15V or 10V CMOS systems to 5V CMOS/TTL systems
• General-purpose hex buffer applications requiring signal inversion

Inverter Gates Procurement Notes

Verify the specific suffix ELNF against the manufacturer's official documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status and environmental restrictions before procurement. Ensure the component meets the required operating temperature range and voltage ratings for the intended application environment.

Inverter Gates Selection Notes

Select this component when an inverting hex buffer is required for interfacing between different logic families. Consider the wide input voltage tolerance relative to the supply voltage. Evaluate the propagation delay and output drive strength requirements against the datasheet specifications for the target supply voltage.

Inverter Gates Part Context

This part belongs to the TC4049B/TC4050B family of CMOS digital integrated circuits. The TC4049B is the inverting version, while the TC4050B is non-inverting. Both contain six buffer circuits designed for high-speed operation and robust interfacing capabilities within the 4000B series architecture.

Inverter Gates Replacement Considerations

Check for direct pin-compatible alternatives such as the TC4049BP variant if leaded packaging is acceptable. Verify functional equivalence with other manufacturers' 4000B series hex inverters, ensuring matching voltage ranges and electrical characteristics.
