Frequently Asked Questions
How does the CD74HC4051M96 select one of its 8 analog input channels?
The CD74HC4051M96 uses a 3-bit binary address on pins A, B, and C to select any one of 8 analog channels connected to I/O pins. For example, address 000 connects channel 0, while 111 connects channel 7. This allows a microcontroller to multiplex 8 sensor signals to a single ADC input, reducing pin count and cost.
What on-resistance does the CD74HC4051M96 exhibit and how does it affect signal accuracy?
The CD74HC4051M96 has a typical on-resistance of approximately 70 Ω when operating at 5 V supply. In high-impedance ADC front-ends, this on-resistance causes a small voltage drop that must be budgeted in the error analysis. For 12-bit ADC accuracy, the source impedance plus the 70 Ω switch resistance should be low relative to the ADC input impedance.
Can the CD74HC4051M96 handle bidirectional analog signals in demultiplexer mode?
Yes, the CD74HC4051M96 operates bidirectionally, functioning as either a multiplexer or demultiplexer. In demultiplexer mode, the common I/O port receives an analog signal and routes it to one of 8 output channels selected by the 3-bit address. The analog signal range must stay within the supply rails (2 V to 6 V) for linear operation.
