General Description The DP8343/NS32443 provides complete decoding of data for high speed serial data communications. In specific, the DP8343/NS32443 receiver recognizes biphase serial data sent from its complementary chip, the DP8342 transmitter, and converts it into 8 bits of parallel data. These devices are easily adapted to generalized high speed serial data trans-mission systems that operate at bit rates up to 3.5 MHz. The DP8343/NS32443 receiver and the DP8342 transmitter are designed to provide maximum flexibility in system deigns. The separation of transmitter and receiver functions allows addition of more receivers at one end of the biphase line without the necessity of adding unused transmitters. This is advantageous in control units where the data is typically multiplexed over many lines and the number of receivers generally exceeds the number of transmitters. The separation of transmitter and receiver function provides an additional advantage in flexibility of data bus organization. The data bus outputs of the receiver are TRI-STATED, thus enabling the bus configuration to be organized as either a common transmit/receive (bi-directional) bus or as separate transmit and receive busses for higher speed. Features DP8343/NS32443 receives 8-bit data bytes Separate receiver and transmitter provide maximum system design flexibility Even parity detection High sensitivity input on receiver easily interfaces to coax line Standard TTL data input on receiver provides generalized transmission line interface and also provides hysteresis Data holding register Multi-byte or single byte transfers TRI-STATE receiver date outputs provide flexibility for common or separated transmit/receive data bus operation Data transmission error detection on receiver provides for both error detection and error type definition Bipolar technology provides TTL input/output compatibility with excellent drive characteristics Single 5V power supply operation
