Description

The 74HCT4052D,112 is a dual SP4T (single-pole quad-throw) analog switch commonly used as a 4:1 multiplexer/demultiplexer in both analog and digital applications. It features two switches, each with four inputs/outputs and a common input/output. The switch has a digital enable input and two digital select inputs, all of which are shared between both switches. The switch is turned off when the digital enable input is high. Input clamping diodes make it easy to interface the inputs with voltages in excess of VCC, by allowing the use of current limiting resistors.

Specifications and features

The 74HCT4052D,112 has:

• Wide analog input voltage range from -5 V to +5 V
• Low ON resistance of 60-80 ohms (typical)
• Logic level translation allows 5 V logic to communicate with ±5 V analog signals
• 'Break before make' built-in to prevent both switches from being on at the same time
• Compliance with JEDEC standard no. 7A
• Input levels: CMOS for 74HC4052 and TTL for 74HCT4052
• ESD protection that exceeds 1000V
• Operating temperature ranges from -40°C to +85°C and -40°C to +125°C

Application Scenarios

The 74HCT4052D,112 is commonly used in the following applications:

• Analog multiplexing and demultiplexing
• Digital multiplexing and demultiplexing
• Signal gating

Comparison

• Wide analog input voltage range allows for greater flexibility in selecting voltages
• Low ON resistance minimizes signal attenuation and distortion
• 'Break before make' feature prevents signal overlap and crosstalk between switches
• ESD protection that exceeds 1000V reduces the risk of damage to the switch during handling or operation
• Compliance with JEDEC standard no. 7A simplifies design requirements and ensures compatibility with other components

• This model may not be suitable for applications that require more than two switches
• The selection of input and output pins may not be as intuitive as other multiplexer/demultiplexer chips
