Functional Features

The SN74HC158PWT is a 4-to-1 data selector/multiplexer IC. It allows the selection of one out of four input lines (A0-A3) based on the binary value of the control inputs (E, OE). The selected input is then routed to the output pin (Y). It operates at high speed and consumes low power, making it suitable for various applications.

Advantages and Disadvantages

Advantages: - High-speed operation - Low power consumption - Wide supply voltage range - Compact TSSOP-16 package

Disadvantages: - Limited number of input lines (4-to-1)

Working Principles

The SN74HC158PWT uses a combination of control inputs (E, OE) and address inputs (A0-A3) to select one of the four data inputs (B, C, D) and route it to the output pin (Y). When the enable input (E) is high, the multiplexer is enabled. The output is determined by the binary value of the address inputs. The output remains in the high-impedance state when the output enable input (OE) is low.

Detailed Application Field Plans

The SN74HC158PWT can be used in various applications, including but not limited to: - Data routing and selection in digital systems - Address decoding in microcontrollers - Signal multiplexing in communication systems - Input selection in analog-to-digital converters
