Product Overview: SN74HC158PWT

The SN74HC158PWT is a high-performance, quadruple 2-line to 1-line data selector/multiplexer designed and manufactured by Texas Instruments. This integrated circuit is part of the HC family, which is well-known for its high-speed CMOS technology. The device is specifically engineered to operate with a 2V to 6V power supply, making it versatile for various applications.

The SN74HC158PWT comes in a TSSOP (Thin Shrink Small Outline Package) with 16 pins, ensuring a compact footprint on printed circuit boards. It features four identical data selectors/multiplexers, each with two input lines (A and B), one output line (Y), and a common data select input (S). When the select input (S) is low, the A input is selected and passed to the output, whereas a high select input causes the B input to be routed to the output.

One of the key attributes of this multiplexer is its high-speed performance, which is characterized by a typical propagation delay time of only 13 ns with a 5V power supply. This makes the SN74HC158PWT an excellent choice for high-speed data processing and communication systems.

Additional features of the SN74HC158PWT include:

• Low power consumption: The device has a typical quiescent power consumption of only 80 µA, making it suitable for battery-operated equipment.
• High noise immunity: The HC family is known for its excellent noise immunity, which is crucial for maintaining signal integrity in noisy environments.
• Wide operating temperature range: The device can operate over a temperature range of -40°C to 85°C, accommodating industrial and automotive applications.

This multiplexer is commonly used in digital signal routing, data selection, and various forms of signal processing where multiple input signals need to be directed to a single output line. Its high-speed and low-power characteristics, along with robust noise immunity, make the SN74HC158PWT an ideal choice for designers looking for a reliable and efficient data selector/multiplexer for their digital systems.
