For N-bit serial to parallel convertor, N number of D flip-flops will be required. Go ahead-use your existing parallel printer with your serial PC The converter is powered from the RS-232 interface, which makes it easy to use. The 8251A is a USART and is capable of Full Duplex communication. The basic structural component of the shift register is negative edge triggered D flip-flop. >Parallel Converter is the perfect solution for day-to-day print jobs when all you need are reliable printouts. There are three types of serial -to-parallel/parallel -to-serial converter chips (1) Universal Synchronous Receiver/ Transmitter (USRT), (2) Universal Asynchronous Receiver/Transmitter (UART), and (3) Universal Synchronous/Asynchronous Receiver/Transmitter (USART). Serial to parallel convertor can also be considered as a serial-in parallel-out shift register. is a leading manufacturer of IT connectivity solutions, including Serial ATA and Ultra ATA Controllers, FireWire, USB, and legacy I/O adapters.

A serial to parallel converter comes to rescue in these situations. A device that converts a spatial distribution of signals that represent information into a corresponding time sequence of signals that represent the same information, such that each of the parallel input signals requires a separate channel, i.e., a parallel port, while the serial output requires only a single channel, i.e., a serial port.

Note: Parallel-to-serial converters are used in electronic and fiber optic transmission systems, such as electronic or fiber optic links. A digital device that converts a group of simultaneous inputs on two or more parallel channels, often constituting a specific data unit, such as a byte or a word, into corresponding time-sequenced signal elements on a single channel.
