NXP Semiconductors Analog Switches, Multiplexers, Demultiplexers 74HC4851D,112

The 74HC4851D is an 8-channel analog multiplexer/demultiplexer designed for high-speed applications, compliant with JEDEC standard no. 7A. It features three digital select inputs (S0 to S2) and an active-LOW enable input (E), allowing one of the eight independent inputs/outputs (Y0 to Y7) to be selected for low impedance ON-state operation. When the enable input is HIGH, all switches are in a high-impedance OFF-state. This device incorporates injection-current effect control, which is particularly beneficial in automotive applications where input voltages may exceed the supply voltage. The low ON-state resistance varies with supply voltage, with typical values of 59Ω at 6.0V, 76Ω at 4.5V, and 400Ω at 2.0V. The supply voltage range is from 2.0V to 6.0V, making it versatile for various applications. Additionally, it offers robust ESD protection exceeding 2000V for HBM and 1000V for CDM, along with latch-up performance exceeding 100mA per JESD 78 Class II level A. The 74HC4851D is suitable for analog and digital multiplexing, signal gating, and is particularly recommended for automotive applications.
