NXP 74HCT4051 8-channel Analog Multiplexer/Demultiplexer

The NXP 74HCT4051 is a high-speed Si-gate CMOS device that is pin compatible with low-power Schottky TTL (LSTTL). It is specified in compliance with JEDEC standard no. 7A. The 74HCT4051 is an 8-channel analog multiplexer/demultiplexer with three binary control inputs (S0, S1, and S2), an active-low enable input (E), eight independent inputs/outputs (Yn), a common input/output (Z), and a digital select input, which can be used to connect any one of the eight channels to the common input/output.

This versatile device is useful for multiplexing and demultiplexing digital or analog signals. It features low ON resistance and low OFF leakage current. Control of analog signals up to 20Vpp can be achieved by digital signal amplitudes of 4.5 to 5.5V (from VCC to GND). The device has an ESD protection HBM JESD22-A114E exceeds 2000V and MM JESD22-A115-A exceeds 200V.

The 74HCT4051 operates in a wide temperature range from -40°C to +125°C, making it suitable for a variety of applications in the industrial, communications, and consumer electronics sectors. The multiplexer/demultiplexer can be used in signal gating, modulation/demodulation, and signal multiplexing for analog-to-digital and digital-to-analog conversion systems.

The 74HCT4051 is available in multiple package options, including DIP, SO, SSOP, TSSOP, and DHVQFN. This provides flexibility for various types of circuit boards and space requirements. Its logical behavior is guaranteed over the full voltage range, ensuring reliable operation in a wide range of circuits and applications.

In summary, the NXP 74HCT4051 is a versatile and reliable component for your analog and digital signal processing needs. With its robust ESD protection and wide operating temperature range, it is designed to meet the stringent requirements of modern electronic systems, providing both flexibility and performance.
