NXP 74HCT4052BQ Dual 4-channel Analog Multiplexer/Demultiplexer

The NXP 74HCT4052BQ is a high-performance, dual 4-channel analog multiplexer and demultiplexer that is part of the 74HCT family. This integrated circuit (IC) is designed for multiplexing and demultiplexing digital or analog signals. It is particularly useful in applications where multiple signal lines need to be controlled by a single control signal, making it ideal for data acquisition systems, signal routing, and communication systems.

This versatile device features two independent four-channel multiplexers/demultiplexers with common select logic. Each multiplexer/demultiplexer has four independent inputs/outputs (nY0 to nY3), a common input/output (nZ), and two common binary address inputs (nS0 and nS1). The 74HCT4052BQ operates on a wide voltage range from 2V to 6V, which makes it compatible with TTL levels and capable of interfacing with 5V logic levels with ease.

The device's low "ON" resistance and very low quiescent power dissipation make it efficient for power-sensitive designs. Additionally, the 74HCT4052BQ's low crosstalk between switches and its capability to handle both digital and analog signals up to 10 MHz make it a flexible choice for a wide range of applications.

Key features of the NXP 74HCT4052BQ include:

• Wide analog input voltage range from -5V to +5V
• Low "ON" resistance: 70 Ω (typical) at VCC - VEE = 4.5V
• Logic level translation capability to enable 5V logic to communicate with ±5V analog signals
• Binary address decoding on chip
• Low crosstalk between switches
• Typical break-before-make built-in feature
• ESD protection: HBM JESD22-A114E exceeds 2000V

The 74HCT4052BQ is housed in a DHVQFN16 package, which is a leadless, plastic package with 16 terminals and a body size of 2.5 x 3.5 x 0.85 mm. This compact form factor is suitable for space-constrained applications. The device is specified for operation from -40°C to +125°C, ensuring reliable performance across a wide range of environmental conditions.

With its robust design and versatile functionality, the NXP 74HCT4052BQ is a smart choice for designers looking to implement efficient signal routing in their digital or analog systems.
