Logic - Signal Switches, Multiplexers and Decoders are used in many electronic systems for signal control and management. Among them, the 74HC4514PW is a high-speed CMOS 4-to-16 line decoder/demultiplexer. It is used to convert binary data from a 4-bit code in one group of inputs, referred to as the A input lines, to one of 16 mutually exclusive outputs to be activated in the Y output lines.

The 74HC4514PW offers low power dissipation, high noise immunity and high speed logic operations, making it ideal for multi-dimensional motion control, opto-isolated video displays, serial port address decoding, as well as many other applications.

The 74HC4514PW contains four 1-of-16 decoders and is designed with a priority-encoded address. The A0–A3 inputs select 1 of 16 output terminals (Y0–Y15). When HIGH on A0–A3 is encountered, the outputs are disabled. The output enable (OE) input when LOW places the outputs in the high-impedance OFF-state, regardless of the logic levels of the A0–A3 inputs. The 74HC4514PW also contains clock and inverse inputs (CLK and CLK). These are provided in order to give the device decoding abilities.

The working principle of the 74HC4514PW is quite simple. All of the A0–A3 inputs are connected to the decoders, and the decoders activate the output lines according to the pre-programmed instruction bits. The priority-encoded inputs allow for multiple input codes to be decoded to the same output line. The CLK and CLK inputs allow for the device to store and delay the inputs until the next clock trigger is generated, allowing for further decoding functions.

The 74HC4514PW is used in many different applications, such as motion control systems, opto-isolated video displays, serial port address decoding, decoder/multiplexer for addressable switches, and data communications systems. The device can be used to output a digital signal based on the binary input code, and can be used to control and manage multiple digital inputs.

In summary, the 74HC4514PW is a high-speed CMOS 4-to-16 line decoder/demultiplexer. It is used in many applications, such as motion control systems, opto-isolated video displays, and serial port address decoding. It contains four 1-of-16 decoders and is designed with a priority-encoded address. The working principle of the device is quite simple, as the A0–A3 inputs are connected to the decoders, and the decoders activate the output lines according to the pre-programmed instruction bits. The CLK and CLK inputs allow for the device to store and delay the inputs until the next clock trigger is generated, allowing for further decoding functions.
