1. General description
The 74HC4052; 74HCT4052 is a dual single-pole quad-throw analog switch (2 × SP4T) suitable
for use in analog or digital 4:1 multiplexer/demultiplexer applications. Each switch features four
independent inputs/outputs (nY0, nY1, nY2 and nY3) and a common input/output (nZ). A digital
enable input (E) and two digital select inputs (S0 and S1) are common to both switches. 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
• CMOS low power dissipation
• High noise immunity
• Latch-up performance exceeds 100 mA per JESD 78 Class II Level B
• 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 ‘break before make’ built-in
• Complies with JEDEC standards:
• JESD8C (2.7 V to 3.6 V)
• JESD7A (2.0 V to 6.0 V)
• Input levels:
• For 74HC4052: CMOS level
