Product Overview: 74HC4351D by NXP Semiconductors

The 74HC4351D is a high-speed Si-gate CMOS device and is pin compatible with the HEF4051B. It is part of a range of analog multiplexers/demultiplexers from NXP Semiconductors, which includes devices with different numbers of channels and varying electrical characteristics. This particular model, the 74HC4351D, is an 8-channel analog multiplexer/demultiplexer with three digital select inputs (S0, S1, and S2), an active LOW enable input (E), eight independent inputs/outputs (Yn), a common input/output (Z), and a digital common ground (Vss).

The device features low ON resistance and low OFF leakage current. It is capable of handling both digital and analog signals, allowing it to pass frequencies up to 70 MHz. This makes it suitable for a variety of applications, including signal gating, channel selection, and mixing in consumer electronics, telecommunications, and data acquisition systems.

The 74HC4351D operates over a recommended VDD to VSS range of 2.0 to 10.0 V and has a VDD to VEE range of 2.0 to 10.0 V. It can be used in analog applications such as multiplexing and demultiplexing of signals, sample and hold circuits, and in digital applications to perform boolean functions. The device's low power consumption makes it ideal for battery-operated devices.
