Texas Instruments 6-Channel Inverting Voltage Buffer & Converter Combination Circuit, 16-Pin SOIC CD4049UBD

Texas Instruments CD4049UBD is a 6-channel inverting voltage buffer and converter combination circuit housed in a compact 16-pin SOIC package. It belongs to the 4000 CMOS logic family designed for reliable voltage buffering and conversion with inverting polarity output. This device operates over a broad supply voltage range of 3 to 18 volts, with a maximum supply voltage tolerance of 20 volts, making it suitable for versatile electronic and semiconductor applications.

The CD4049UBD features six channels with single-ended input type, providing voltage output with inversion. Its typical maximum propagation delay time is 120 nanoseconds under a specified load capacitance, supporting responsive circuit timing. The device supports an operating temperature range from -55°C to 125°C, ensuring stable performance under harsh industrial or environmental conditions. Its ultra-low supply current consumption of only 1 microampere enhances power efficiency in battery-powered or low energy systems.

This surface-mount component is designed with a 16-pin Small Outline Integrated Circuit (SOIC) package, featuring compact dimensions of 1.58 mm height and 9.9 mm length, enabling efficient PCB space utilization. The maximum high-level output current is -5.2 mA, and the maximum low-level output current is 26 mA, allowing it to drive various loads effectively. The device lacks Schmitt trigger input, which means it uses standard buffer logic compatible with the 4000 series logic family.
