Frequently Asked Questions
How much output current can the CD4050BD source or sink per channel?
Each of the 6 buffer channels in the CD4050BD can sink up to 18 mA (I_ol = 0.018 A), making it suitable for driving TTL inputs and moderately capacitive loads without additional driver stages.
Can the CD4050BD interface CMOS logic outputs to TTL inputs in a 5 V system?
Yes, the CD4050BD is specifically designed for CMOS-to-TTL level shifting. Its 18 mA sink current meets TTL input current requirements, and operating at 5 V ensures output high and low levels are within standard TTL thresholds for reliable interfacing.
What is the maximum load capacitance the CD4050BD can drive reliably?
The CD4050BD is rated for a 50 pF load capacitance per channel, which accommodates typical PCB trace capacitance and TTL or CMOS gate inputs. For higher capacitance loads exceeding 50 pF, propagation delay increases and additional buffering may be required.
Which package is the CD4050BD available in and what are its pin count dimensions?
The CD4050BD comes in a 16-pin Small Outline Package (SO-16 / SOIC-16) with standard 1.27 mm pitch, offering a compact footprint of approximately 10 mm x 4 mm, suitable for space-constrained PCB layouts in industrial and consumer electronics designs.
