CD4051BE Description

Short technical summary and product information.

The CD4051BE from RCA is a versatile CMOS analog multiplexer and demultiplexer. This device features an 8:1 configuration, allowing for the selection of one of eight analog or digital input signals.

Key electrical specifications include a wide single supply voltage range from 3V to 20V and a dual supply range of ±3V to ±10V. It offers a low ON resistance of typically 125Ω at VDD = 15V and a low channel leakage current of ±10pA typical at VDD = 15V. The bandwidth is rated at 20MHz, making it suitable for various signal routing applications.

Designed for broad compatibility, the CD4051BE supports digital signal levels from 3V to 20V and analog signal levels up to 20VP-P. It operates across a wide temperature range of -55°C to 125°C. The device also features break-before-make switching and ESD protection.

Available in multiple package options including SOIC, TSSOP, PDIP, and SOP, the CD4051BE offers flexibility for different PCB designs. Its pin compatibility with industry-standard 4051 devices simplifies upgrades and replacements.
