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
