SN75176BP Differential Bus Transceiver 5V 60mA IC DIP-8 (ORIGNAL)
The SN75176BP is a differential bus transceiver IC designed for bidirectional data communication over balanced transmission lines. It integrates both a differential line driver and a differential line receiver in a single device, enabling half-duplex communication based on RS-485 and RS-422 standards.
Manufactured by Texas Instruments, this device is optimized for reliable data transmission in electrically noisy environments, making it ideal for industrial communication systems. The transceiver supports multipoint bus configurations, allowing multiple devices to communicate over the same differential bus.
Features:
- Bidirectional transceivers.
- Meets or exceeds the requirements of ANSI standards TIA/EIA-422-B and TIA/EIA-485-A and ITU Recommendations V.11 and X.27.
- Designed for multipoint transmission on long bus lines in noisy environments.
- 3-state driver and receiver outputs.
- Individual driver and receiver enables.
- Wide positive and negative input/output bus voltage ranges.
- ±60mAm maximum driver output capability.
- Thermal shutdown protection.
- Driver positive and negative current limiting.
- 12kΩ minimum receiver input impedance.
- ±200mV receiver input sensitivity.
- 50mV typical receiver input hysteresis.
- Operates from a single 5V supply.
