General description

The 74HC4052; 74HCT4052 is a dual single-pole quad-throw analog switch (2x 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.

Features and benefits

 Wide analog input voltage range from 5 V to +5 V

 Low ON resistance:

 80  (typical) at VCC  VEE = 4.5 V

 70  (typical) at VCC  VEE = 6.0 V

 60  (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 standard no. 7A

 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

Applications

 Analog multiplexing and demultiplexing

 Digital multiplexing and demultiplexing

 Signal gating
