74HC4852
Dual 4-channel analog multiplexer/demultiplexer with injection-current effect control
Rev. 02 -- 30 May 2007 Product data sheet

1. General description
The 74HC4852 is a high-speed Si-gate CMOS device and is specified in compliance with JEDEC standard no. 7A. The 74HC4852 is a dual 4-channel analog multiplexer or demultiplexer with common select inputs (S0 and S1). Both multiplexers have a common active LOW enable input (E), four independent inputs/outputs (pins nY0 to nY3) and a common input/output (pin nZ). The device features injection-current effect control, which has excellent value in automotive applications where voltages in excess of the supply voltage are common. With E LOW, two of the eight switches are selected (low impedance ON-state) by S0 and S1. With E HIGH, all switches are in the high-impedance OFF-state, independent of S0 and S1. The injection-current effect control allows signals at disabled analog input channels to exceed the supply voltage without affecting the signal of the enabled analog channel. This eliminates the need for external diode/resistor networks typically used to keep the analog channel signals within the supply-voltage ra
nge.
