Frequently Asked Questions
What bandwidth does the CD74HC4351EE4 support for analog signal switching?
The CD74HC4351EE4 provides a nominal bandwidth of 180 MHz, enabling it to route high-frequency analog signals with minimal attenuation, making it suitable for video, audio, and RF-adjacent multiplexing applications.
Can the CD74HC4351EE4 operate from a dual supply, and what voltage range is supported?
Yes, the CD74HC4351EE4 can operate from a dual supply with VCC-VEE range of 2 V to 10 V, and also works from a single supply of 2 V to 6 V, offering flexibility across different analog front-end designs.
How many analog channels does the CD74HC4351EE4 switch, and what package is used?
The CD74HC4351EE4 provides 8 analog channels in a 20-pin DIP package, allowing selection of one of 8 single-ended inputs or outputs through a 3-bit binary address, suitable for through-hole prototyping boards.
In what applications is the CD74HC4351EE4 preferred over a lower-channel-count multiplexer?
The CD74HC4351EE4 is preferred in data acquisition systems requiring 8 sensor inputs sharing a single ADC, reducing component count compared to using multiple 4-channel or 2-channel multiplexers with separate address decoding logic.
