To all our customers
Regarding the change of names mentioned in the document, such as Hitachi
Electric and Hitachi XX, to Renesas Technology Corp.
The semiconductor operations of Mitsubishi Electric and Hitachi were transferred to Renesas
Technology Corporation on April 1st 2003. These operations include microcomputer, logic, analog
and discrete devices, and memory chips other than DRAMs (flash memory, SRAMs etc.)
Accordingly, although Hitachi, Hitachi, Ltd., Hitachi Semiconductors, and other Hitachi brand
names are mentioned in the document, these names have in fact all been changed to Renesas
Technology Corp. Thank you for your understanding. Except for our corporate trademark, logo and
corporate statement, no changes whatsoever have been made to the contents of the document, and
these changes do not constitute any alteration to the contents of the document itself.

HD74LV4066A
Quad. Analog Switches / Quad. Multiplexers
ADE-205-285B (Z)
3rd. Edition
July 2001
Description
The HD74LV4066A handles both analog and digital signals, and enables signals of either type with
amplitudes of up to 5.5 V (peak) to be transmitted in either direction (at VCC = 0 V to 5.5 V).
Each switch section has its own enable input control (C). A high-level voltage applied to C turns on the
associated switch section.
Applications include signal gating, chopping, modulation or demodulation (modem), and signal
multiplexing for analog-to-digital and digital-to-analog conversion systems.
Features
• VCC = 2.0 V to 5.5 V operation
• All control inputs VIH (Max.) = 5.5 V (@VCC = 0 V to 5.5 V)
