描述 Description

The 74HC4051; 74HCT4051 is a single-pole octal-throw analog switch (SP8T) 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.

特性 Features

• Wide analog input voltage range from -5 V to +5 V
• CMOS low power dissipation
• High noise immunity
• Complies with JEDEC standards
• JESD8C (2.7 V to 3.6 V)
• JESD7A (2.0 V to 6.0 V)

• Latch-up performance exceeds 100 mA per JESD 78 Class II Level B
