7. 74HC4052 brief introduction:
The M74HCT4052 is a dual four-channel analog MULTIPLEXER/DEMULTIPLEXER
fabricated with silicon gate C2MOS technology and it is pin to pin compatible with the equivalent
metal gate CMOS4000B series. It contains 8 bidirectional and digitally controlled analog
switches.
Feature:
•
Low power dissipation:
ICC = 4mA (MAX.) at TA=25°C
•Logic level translation to enable
TTL logic signal to communicate
With ±5V analog signal
• Low "ON" resistance:
70W TYP. (VCC - VEE = 4.5V)
50W TYP. (VCC - VEE = 9V)
•Wide analog input voltage range: ±6V
•Fast switching: tpd = 13ns (TYP.) at TA = 25 °C
• Low crosstalk between switches
• High ON/OFF output voltage ratio
•Wide operating supply voltage range (VCC - VEE) = 2V TO 12V
• Low sine wave distortion: 0.02% at VCC - VEE = 9V
•Compatible with TLL outputs: VIH = 2V(MIN.) VIL = 0.8V (MAX.)
• PIN and function compatible with 74 series 4052
