The SN74AHCT158DGVR is a logic device belonging to the category of Logic - Signal Switches, Multiplexers, and Decoders. It is a 16-bit multiplexer/demultiplexer device with output enable pins. This device is designed to work with LVTTL and LVCMOS logic families and operates over the industrial temperature range of -40°C to +125°C. The pin-out diagram of the device is provided below.

The SN74AHCT158DGVR is widely used in applications such as networking, datacommunication, as well as interface with analog and digital signals. It is also suitable for data transmission and communication interfaces, signaling switches, and bus arbitrations. The device has the following unique features.

• TTL/CMOS Logic Compatible
• Wide Operating Voltage 3V to 5V
• Low Power Consumption
• High Speed Response
• Low On State Resistance, Low Cost

In terms of its working principle, the SN74AHCT158DGVR has four data input ports and two output ports. The data input ports are used to supply the logic inputs to the multiplexer. The outputs are controlled by two output enable pins, OEA and OEB. These pins provide the control signals necessary to activate the appropriate output. When OEA is low, the output will be activated and when OEB is low, the output will be deactivated. Upon receiving a high-level logic signal from the input port, the output will be set to the high-level logic signal. This process is called multiplexing, which is the use of a single channel to send multiple logic signals.

Additionally, the SN74AHCT158DGVR also features an output latched and latch control pin (LC). The LC pin provides the ability to latch the multiplexer output when the device is used in sequential mode. When the device is used in non-sequential mode, the LC pin will be used to read the output state of the device. Lastly, the device has two active low reset pins, RSTA and RSTB, which can be used to reset the device to its power-on state.

In conclusion, the SN74AHCT158DGVR is a versatile logic device that belongs to the category of Logic - Signal Switches, Multiplexers, and Decoders. It is suitable for applications where data transmission, communication interface, signaling, and bus arbitration is required. The device has four data input ports and two output ports, and is designed to work with LVTTL and LVCMOS logic families. Additionally, the device also features a reset and latch pin to provide enhanced control on its operation.
