The MC14049UBPC is a Hex Inverting Buffer/Converter manufactured by Freescale Semiconductor (now NXP). This CMOS integrated circuit contains six independent inverting buffers. It is primarily used to convert CMOS logic levels to TTL logic levels or to provide high-current drive capability. It can also be used as a standard inverting buffer.

Applications:

• CMOS to TTL logic level conversion
• High-current drivers
• Inverting buffers
• LED drivers
• Relay drivers

Features:

• High Sink Current: 6 mA at VOUT = 0.5 V (typ) at VDD = 5 V
• CMOS Logic Level Conversion
• Supply Voltage Range = 3.0 V to 18 V
• High Noise Immunity: 0.45 VDD (typ)
• Low Power Consumption

Benefits:

• Enables interfacing between CMOS and TTL logic families.
• Provides high current drive for external loads.
• Reduces the number of components in a system.
• Offers a wide operating voltage range.

Additional Details:

The MC14049UBPC is available in a 16-pin DIP package. Each of the six inverters is independent. The device can sink significantly more current than standard CMOS gates, making it suitable for driving LEDs, relays, and other high-current loads. Detailed datasheets are available online for more information on specific characteristics, application notes, and circuit diagrams. It should be noted that these are unbuffered inverters; therefore, propagation delay can vary as a function of voltage and load.
