TI SN75HVD12P

SN65HVD10, SN75HVD10, SN65HVD11, SN75HVD11, SN65HVD12, and SN75HVD12 bus transceivers each integrate a three-state differential line driver and a differential-input line receiver operating from a single 3.3V supply. These devices are designed for balanced transmission lines and meet or exceed ANSI standard TIA/EIA-485-A and ISO 8482:1993. These differential bus transceivers are monolithic ICs intended for bidirectional data communications on multipoint bus transmission lines. The driver and receiver have active-high and active-low enable inputs that can be externally connected together for direction control. Extremely low standby supply current can be achieved by disabling both the driver and receiver.

The driver differential outputs and receiver differential inputs are internally connected to form a differential I/O bus port, designed to present minimum loading on the bus when the driver is disabled or VCC = 0. These devices feature a wide common-mode voltage range in both polarities, making them suitable for party-line applications.
