PRODUCTION DATA
The CD4051B-Q1 line of multiplexers and demultiplexers can accept a wide range of digital and analog signal levels. Digital signals range from 3V to 20V, and analog signals are accepted at levels ≤ 20V. The devices have low ON resistance, typically 125Ω over 15VP-P signal input range for VDD – VEE = 18V. This feature allows for very little signal loss through the switch.
The CD4051B-Q1 devices also have high OFF resistance, which keeps from the devices from wasting power when the switch is in the OFF position, with typical channel leakage of ±100pA at VDD – VEE = 18V.
Binary address decoding on the chip makes channel selection simple. When channels are changed, a break-before-make system eliminates channel overlap.
