74HCT4051D,118

The 74HCT4051D is a single-pole octal-throw (SP8T) Analog Switch suitable for use in analog or digital 8:1 multiplexer/demultiplexer applications. The switch features three digital select inputs (S0, S1 and S2), eight independent inputs/outputs (Yn), a common input/output (Z) and a digital enable input (E\). When E\ is high, the switches are turned off. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.

• Logic level translation to enable 5V logic to communicate with ±5V analog signals
• Typical break before make built-in
• Complies with JEDEC standard No. 7A
