The SN74AS286N is a parity generator/checker family device typically used for generating even parity and for checking odd parity or even parity. This device is designed for applications using three-state outputs in silicon-gate technology.
The SN74AS286N generates and checks 8-bit data frame parity for data transfers between data frames with different bit orderings. Parity is generated or checked on inputs by selecting the incoming data of the 8 bits and performing the logic operation determined by the chosen parity type. Similarly, the device can be used to check parity on output or generate a parity check data to be compared against an incoming data stream. The alert pin indicates a parity mismatch when generating or detecting parity.
The SN74AS286N is a low-power, easy-to-use device that offers a wide range of parity-generating and checking capabilities. It is pin-compatible with similar devices and is suitable for applications that require an efficient and cost-effective parity-generating and checking solution.
The SN74AS286N operates in two modes: generation mode for output parity generation and detection mode for parity checking of incoming data bits. The operating configuration and modes are selected using two select pins, SEL0 and SEL1. The parity type to be generated or checked is also determined by these pins. The output pin indicate parity mismatch (alert pin) if an invalid data frame detected in detection mode.
The SN74AS286N uses an optimized combination of silicon-gate CMOS technology and gate count to deliver high-performance, low-power parity-check solutions in both single-chip and serial-port configurations. The device can be applied to both generator or checker applications, due to its two operating modes. In addition, the specific configurations provide up to 8-bit data word parity generation/detection.
The SN74AS286N requires a supply voltage of 4.75 to 5.25V and a maximum of 10mA of current. It is completely static and only requires a low clock frequency to operate. The SN74AS286N has a low pin count and consists of two 8-bit I/O buffers, an 8-bit parity generator/checker, and an alert pin.
A typical application of the SN74AS286N is for error detection and control in data frame transfers. It can generate/check parity on 8-bit frames and detect any incorrect data frames when used in detection mode. The SN74AS286N can be used in various other applications, such as providing parity protection to data storage, digital video signal processing, and communication devices that require parity protection.
