DESCRIPTION

The HEF4755V transceiver is a circuit for serial data communication. It provides maximum transmission security and effectiveness. Therefore, in addition to the normal precautions, it contains a programmable digital bit-check, a programmable CRC (Cyclic Redundancy Check; Hamming distance 4 or 6) and format protection.

FEATURES

• Transmission rate:

• Inputs: standard LOCMOS

• Outputs: TTL compatible (1 TTL load)

• Operating ambient temperature range: −40 to + 85 °C

• Transmit or receive a serial binary data stream

• Start bit generation and recognition

• Format protection and checking

• Redundancy byte generation and checking

• Digital bit check

• Error recognition and error distinguishing

• 8-bit parallel input/output transfer
