The MC75451P is an integrated circuit (IC) component that belongs to the MC75451 series of quadruple differential line receivers. It is primarily designed to receive and convert differential signals present on twisted-pair or ribbon cable lines into corresponding TTL-compatible outputs.
Key features of the MC75451P include:
1. Quad Differential Line Receiver: The IC consists of four separate differential line receivers within a single chip. Each receiver provides a high-input impedance and high common-mode rejection ratio (CMRR).
2. TTL-Compatible Outputs: The MC75451P integrates output buffers that convert the received differential signals into TTL-compatible logic levels. The outputs are capable of directly driving standard TTL loads without requiring additional external components.
3. Wide Operating Voltage Range: This IC operates over a wide power supply voltage range of 4.75V to 5.25V, making it compatible with standard TTL levels.
4. High-Speed Operation: The MC75451P is designed for high-speed data transmission applications, with a maximum data rate of up to 20 Mbps. It is well-suited for applications involving serial data communication, such as RS-422 or RS-485 networks.
5. ESD Protection: The IC incorporates built-in ESD protection on the inputs, which safeguards against electrostatic discharges that may occur during handling or operation
