SN75HVD07DR

Texas Instruments · RS-485 / RS-422 ICs · SOIC-8

SN75HVD07DR from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 R output Receiver output, which is enabled by the active-low receiver enable RE as stated in the datasheet's receiver enable description.
2 RE input Active-low receiver enable; the datasheet states that DE and RE can be externally connected together to function as direction control.
3 DE input Active-high driver enable; the datasheet states that DE and RE can be externally connected together to function as direction control.
4 D input Driver data input that drives the differential I/O bus port (A and B) when the driver is enabled.
5 GND power_in Ground reference pin for the device.
6 A bidirectional Bus pin of the differential I/O bus port, where the driver outputs and receiver inputs connect internally; the datasheet states the port offers minimum loading to the bus when the driver is disabled or not powered.
7 B bidirectional Bus pin of the differential I/O bus port, where the driver outputs and receiver inputs connect internally; the datasheet states the port offers minimum loading to the bus when the driver is disabled or not powered.
8 VCC power_in Positive supply pin for the device; the supply voltage limits are given in the Absolute Maximum Ratings and Recommended Operating Conditions, which are not in the pages provided.
