The SN74AHCT158PWR is a 16-bit CMOS switch. It belongs to the ‘Analog Multiplexers – Logic – Signal Switches,Multiplexers, Decoders’ family, which are suitable for use in many applications, predominantly in industrial automation,wireless or wired communication. The main features of this chip include high operating temperature range and lowinput current (only 1μA). It also has an adjustable power supply and an integrated level shifter which can switchfrom between 2.7V to 5V.

The SN74AHCT158PWR is a perfect choice for applications that require high bandwidth and low DC power consumption.It has a wide range of uses in consumers, medical, industrial and communications sectors, including motor controllers,sensors, and other mixed-signal applications. It is suitable for use in communications systems such as Ethernet, USB, andBluetooth. It can also be used as a general-purpose switch, as well as in robotics applications.

The SN74AHCT158PWR is a 16-bit analog multiplexer/demultiplexer with an internal power supply. It operates with2.7V, 3.3V, or 5V. It can be used in applications such as switching, signal routing, and multiplexing. Internally, itcontains 16 analog inputs, 16 analog outputs and can be operated in either parallel or serial mode. The SN74AHCT158PWRcan be configured to multiplex four 8-bit buses, allowing 8-bit data to be routed between 4 different control signals,making it ideal for communication system applications. Additionally, it includes a built-in low-voltage differentialsignaling (LVDS) as well as a power drop detection circuit.

The SN74AHCT158PWR also provides a low-power solution for applications that require high switching speeds. Itutilizes a half-bridge switching architecture to minimize the supply voltage, allowing for a maximum power consumption ofonly 1mA. It also offers adjustable power down and level shifting features. The internal logic level shifter allows theSN74AHCT158PWR to operate with either 2.7V, 3.3V, or 5V supplies. Adjustable power down enables designers to reducepower consumption while not in use.

The SN74AHCT158PWR features an internal CMOS logic gate structure, which provides fast switching speeds and improvednoise immunity. The multiplexer and demultiplexer are based on two 8-bit-wide multiplexers. Each multiplexer is capableof connecting either one of the sixteen input channels to one of the sixteen output channels. This allows for simultaneousswitching between different logic levels, achieving a wide range of switching speeds. Additionally, the SN74AHCT158PWRfeatures an optional logic output buffer which can be connected to the 8-bit multiplexer’s output. The integratedhigh-speed differential inputs enable fast switching speeds.

The SN74AHCT158PWR is also capable of driving high voltage/current loads (up to 50V/100mA). These loads can bedriven at rates up to 80MHz. A driver circuit is included to drive the multiplexer output lines. In addition, theSN74AHCT158PWR contains a power down feature, allowing the multiplexer to be placed in a low-power state when not inuse. This can be beneficial when using the device in power-sensitive applications.

The SN74AHCT158PWR demonstrates excellent versatility, making it suited for a wide variety of applications. Itbelongs to the ‘Analog Multiplexers – Logic – Signal Switches, Multiplexers, Decoders’ family, and is suitable for usein many industrial automation, wireless and wired communication applications. It is ideal for applications requiringhigh bandwidth and low DC power consumption, and can be used in motor controllers, sensors, and other mixed-signalapplications. It also provides a low-power solution for applications that require high switching speeds, and featuresan adjustable power down and level shifting feature.
