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

? For 74HCT4052: TTL level

? ESD protection:

? HBM JESD22-A114F exceeds 2000 V

? MM JESD22-A115-A exceeds 200 V

? CDM JESD22-C101E exceeds 1000 V

? Specified from -40 °C to +85 °C and -40 °C to +125 °C

3. Applications
