Overview
The 74HCT4066DB,118 is a quad single-pole single-throw analog switch produced by Nexperia USA Inc. This integrated circuit is part of the 74HC/74HCT family and is designed to handle analog signals. Each switch within the IC features two input/output terminals (nY and nZ) and an active HIGH enable input (nE). When the enable input (nE) is LOW, the analog switch is turned off. The device includes clamp diodes on the inputs, allowing the use of current limiting resistors to interface with voltages exceeding VCC.
The 74HCT4066DB,118 operates with TTL logic levels and is specified to work within a supply voltage range of 4.5 V to 5.5 V. It is available in a 14-lead SSOP package and is rated for operation over a temperature range of -40°C to +125°C.
