The SN75HVD11PG4 is an integrated circuit developed by Texas Instruments for applications as a differential line driver and line receiver. This ultra low-power device is specifically designed for RS-485 communication systems and features a thermal shutdown protection system that guards against bus contention and thermal runaway conditions. This device operates from a single supply between 2.7 and 5.5V, supporting data rates up to 250kbit per second.

As a differential line driver, the SN75HVD11PG4 can send and receive both balanced (differential) and unbalanced (single-ended) signals. It is also capable of driving up to 32 transceivers on the same bus line, using a combination of 75Ω and 80Ω cable. This device has a bus termination that can cope with different bus impedances, and its output is able to withstand up to 12V in high impedance mode.

The SN75HVD11PG4 features single-wire differential line drivers that are capable of transmitting a high-voltage differential signal up to the edge of the repeater junction. The differential line drivers are constructed with advanced Schottky thin film technology that allows for low-loss operation. The device also features an adjustable line receiver offset voltage, which allows for precise adjustment of the receiver’s input threshold. Additionally, the receiver has a low-voltage differential threshold for improved noise immunity.

In order to minimize power consumption, the SN75HVD11PG4 is equipped with a low-power standby mode. This mode allows the device to enter a reduced state of power consumption when it is in standby, while still maintaining the data integrity of the bus line. The device is also designed to reduce the effects of noise and electromagnetic interference on the bus, utilizing internal filters and shielding to minimize the effects of external electrical noise on the bus.

Applications of the SN75HVD11PG4 include PoE (power-over-Ethernet) connections, as well as full-duplex and/or half-duplex communications. The device is also widely used in motor control systems, factory automation and other applications where high-speed data communication is required.
