SN65HVD24DR from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | R | output | Receive data output (digital output). Recovered logic-level data from the differential bus. Enters high-impedance state when RE is deasserted (high). Includes failsafe circuit that drives a high-level output within 250 µs after loss of input signal. |
| 2 | RE | input | Receiver enable, active low (digital input). When held low, the receiver drives the R pin with recovered bus data. When held high, R is placed in high-impedance state. |
| 3 | DE | input | Driver enable, active high (digital input). When high, the differential driver drives the A and B bus outputs from the D input. When low, the driver outputs enter high-impedance state. |
| 4 | D | input | Driver data input (digital input). Logic-level TTL/CMOS input whose state determines the differential polarity driven onto the A/B bus when DE is asserted. |
| 5 | GND | power_in | Local device ground (reference potential, 0 V). |
| 6 | A | bidirectional | Non-inverting RS-485 bus I/O. Driver output or receiver input, complementary to B. Supports common-mode voltage range of -20 V to 25 V and >16 kV HBM ESD. |
| 7 | B | bidirectional | Inverting RS-485 bus I/O. Driver output or receiver input, complementary to A. Supports common-mode voltage range of -20 V to 25 V and >16 kV HBM ESD. |
| 8 | VCC | power_in | Supply voltage input, 4.5 V to 5.5 V (nominal 5 V). Bypass with a 100 nF ceramic capacitor placed close to the pin between VCC and GND. |
