The SN74HC138PWR three-state, high-speed CMOS logic device is a multiplexer/demultiplexer logic integrated circuit with eight data outputs and three binary address inputs. It is designed with a logic level ‘0’ or ‘1’ input on all of its inputs, and due to its active-low output enable (OE) signal, the device can be used to select and multiplex up to eight different data signals into one output. Its main applications include data multiplexing, memory multiplexing, address decoding, interfacing of logic families at different logic levels, and power-on reset circuits.

The SN74HC138PWR is a multiplexer/demultiplexer logic integrated circuit that is able to select and multiplex up to eight different data signals into one output. It has a 3-state, active low output enable which allows it to sample the data signal on one of its 8 data inputs. The data input is selected by the three binary address inputs A, B, and C. It can accept a logic level ‘0’ or ‘1’ input on any of its inputs and can be used to multiplex up to 8 different data signals into one output.

The SN74HC138PWR is a 16-pin dual-in-line package (DIP) with a VCC maximum voltage of 6 Volts, a logic low threshold voltage of 0.8 Volts (VIL), and a logic high threshold voltage of 2.0 Volts (VIH). The logic low and logic high thresholds can be adjusted using external resistors. The device features an active low output enable (OE) signal, which allows the device to switch the data signal on one of its 8 data input pins to the device’s output (Q) pin when OE is set to logic ‘0’.

The SN74HC138PWR is used in many electronic circuits to convert several binary signals into one data signal. It is also used for address decoding and for interfacing logic families at different logic levels. It is a single-ended input device which allows it to be used in address decoding and multiplexing applications. In these applications, the device is able to take up to eight single-ended logic level inputs and combine them into one data output.

The SN74HC138PWR is also used in many power-on reset circuits. It can be used as a reset controller which can detect a drop in the system’s power and trigger the reset signal. It is also used as a reset circuit which can be used to reset the logic units in a system when the power supply to the system is turned on.

In summary, the SN74HC138PWR is a versatile logic integrated circuit which can be used for multiplexing and demultiplexing data, address decoding, and power-on reset circuits. It is a 3-state, active-low output enable device which allows it to accept up to eight input signals and multiplex them into one data output. The device is available in a 16-pin dual-in-line package (DIP) with a logic level low and logic level high threshold voltage of 0.8 Volts and 2.0 Volts respectively. It features an active low output enable (OE) signal, which allows the device to switch the data signal on one of its 8 data input pins to the device’s output (Q) pin when OE is set to logic ‘0’.
