DESCRIPTION

· The 74HC4852; 74HCT4852 are dual single-pole quad-throw analog switches (SP4T) designed for 4:1 multiplexer/demultiplexer applications in analog or digital systems. Each switch includes four independent inputs/outputs and a common input/output, controlled by a digital enable input and two digital select inputs. The device features injection-current effect control, allowing signals at disabled analog input channels to exceed the supply voltage without affecting the enabled channel, eliminating the need for external diode/resistor networks. Inputs include clamp diodes, enabling the use of current limiting resistors to interface inputs to voltages beyond VCC.
