Product data sheet
1 General 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.
2 Features and benefits
• Wide analog input voltage range from -5 V to +5 V • Complies with JEDEC standard no. 7A • Low ON resistance:
– 80 Ω (typical) at VCC - VEE = 4. 5 V – 70 Ω (typical) at VCC - VEE = 6. 0 V – 60 Ω (typical) at VCC - VEE = 9. 0 V • Logic level translation: to enable 5 V logic to communicate with ±5 V analog signals • Typical ‘bre...
