The 74HC/HCT4051 is a high-speed silicon-gate complementary metal-oxide-semiconductor (CMOS) device that is designed to be pin compatible with the "4051" of the "4000B" series. It is compliant with JEDEC standard no. 7A.

Features:

Wide analog input voltage range: ±5V
Low "ON" resistance:
80Ω (typical) at VCC−VEE = 4.5 V
70Ω (typical) at VCC−VEE = 6.0 V
60Ω (typical) at VCC−VEE = 9.0 V
Logic level translation: Allows communication between 5 V logic and ±5 V analog signals
Typical "break before make" behavior built-in
Non-standard output capability
ICC category: Medium-scale integration (MSI)
