- NXP 74HC4051D,  652,  The 74HC4051D is an 8-channel analog multiplexer/demultiplexer with three digital select inputs (S0 to S2),  an active-LOW enable input (E),  eight independent inputs/outputs (Y0 to Y7) & a common input/output (Z). With E LOW,  one of the eight switches is selected (low impedance ON-state) by S0 to S2. With E HIGH,  all switches are in the high-impedance OFF-state,  independent of S0 to S2.VCC & GND are the supply voltage pins for the digital control inputs (S0 to S2,  & E). The VCC to GND ranges are 2.0 V to 10.0 V. The analog inputs/outputs (Y0 to Y7,  & Z) can swing between VCC as a positive limit & VEE as a negative limit. VCC
- VEE may not exceed 10.0 V. The 74HC4051 is a high-speed Si-gate CMOS device & is pin compatible with Low-power Schottky TTL (LSTTL). The device is specified in compliance with JEDEC standard no. 7A. NXP 74HC4051D,  652 SMD HCMOS 8-Channel Analogue Multi-/ Demultiplexer SO-16
