SN74AHC158PW is a 16-bit high-speed CMOS multiplexer integrated circuit made with silicon-gate CMOS technology. It is suitable for bi-directional data exchange and has high reliability, low noise, and speed up processing. The SN74AHC158PW is a member of the Texas Instruments Logic - Signal Switches, Multiplexers, Decoders series and has various applications in communication, computer, peripheral accessories, and other electronic equipment.

The SN74AHC158PW is composed of four 8-bit multiplexers, the input and output are arranged in two separate 16-line platforms. The two input platform signals are named A and B, and the two output platforms are named D and D#. The D output platform is the data bit output, and the #D output platform is the inverse bit output. The working and selection signals are called S0, S1, S2 and S3, respectively, and the enable signal is called E. When the enable signal is high level, the multiplexer is in the working state and the data will be successfully output.

The SN74AHC158PW is an asynchronous signal, which means that the output level (D, #D) is determined only by the input data bits, and no clock is required. In terms of performance parameters, the SN74AHC158PW has high switching speed, low propagation delay, low noise, and good electromagnetic compatibility. The logic level is 2V, the supply voltage is 1.65V-3.6V, the power dissipation is 0.3W, the dynamic current is ±12mA, the static current is 1µA, and the storage temperature range is –50°C to 150°C.

The SN74AHC158PW has various applications and works with other related devices to help in the transmission and exchange of data. Some of the most common applications include communication interface applications and peripheral device connections. In communication interfaces, the SN74AHC158PW can be used as a data switch, data multiplexer, data separator, and other similar applications. In peripheral device connections, the SN74AHC158PW can be used as part of a serial port, signal processor, and other similar applications. Additionally, the SN74AHC158PW is compatible with many related devices and can be used in multiplexer products and signal switching products.

In terms of the operating principle ofSN74AHC158PW, it is based on the presence of PMOS and NMOS FET transistors. When an Enable signal is given, the PMOS FETs and NMOS FETs will change their internal resistance and a data bit is established. The data bit is output thrugh a signal, that is, the SN74AHC158PW willoutputdata for directly related devices which are connected in the inside. When the Enable signal changes, the internal resistance of the PMOS FETs and NMOS FETs changes, the internal voltage of the device changes, and the data output of theSN74AHC158PW changes. The advantage of this operating principle is that power consumption is low and the size of the circuits is small.

In conclusion, the SN74AHC158PW is a 16-bit high-speed CMOS multiplexer integrated circuit designed for data transmission and exchange. It has various applications and works with other related devices to help in the transmission and exchange of data. The operating principle of theSN74AHC158PW is based on the change of internal resistance caused by the Enable signal and the data bit established by the change in resistance. The advantage of theSN74AHC158PW is that power consumption is low and the size of the circuits is small. Therefore, it is suitable for applications that require low-power data transmission and exchange.
