SN65HVD78DRBR

Texas Instruments · RS-485 / RS-422 ICs · SON-8-EP(3x3)

SN65HVD78DRBR from Texas Instruments, in a SON-8-EP(3x3). 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 Receive data output (digital output) from the bus receiver.
2 RE input Active-low receiver enable digital input; the datasheet specifies VIH of 2 V minimum and VIL of 0.8 V maximum for this input.
3 DE input Active-high driver enable digital input; the datasheet specifies VIH of 2 V minimum and VIL of 0.8 V maximum for this input.
4 D input Driver data input (digital input); the datasheet specifies VIH of 2 V minimum and VIL of 0.8 V maximum, with absolute maximum voltage of -0.3 V to 5.7 V.
5 GND power_in Local device ground, the reference potential for the device.
6 A bidirectional Bus I/O: driver output or receiver input, complementary to B; voltage at A or B is limited to -13 V to 16.5 V per the absolute maximum ratings.
7 B bidirectional Bus I/O: driver output or receiver input, complementary to A; voltage at A or B is limited to -13 V to 16.5 V per the absolute maximum ratings.
8 VCC power_in Supply pin; the datasheet specifies 3 V to 3.6 V (3.3 V nominal), with absolute maximum of -0.5 V to 5 V.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
