**Texas Instruments** · Buffers, Drivers, Receivers, Transceivers · DIP-8

SN75119P from Texas Instruments, in a DIP-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 | DI | input | Driver data input, TTL-compatible; absolute maximum input voltage is 5.5 V. |
| 2 | B | bidirectional | Bus terminal B, the driver output and receiver input; receiver inputs are limited to 0 to 6 V and neither receiver input may be taken negative with respect to GND. |
| 3 | A | bidirectional | Bus terminal A, the driver output and receiver reference input; receiver inputs are limited to 0 to 6 V and neither receiver input may be taken negative with respect to GND. |
| 4 | GND | power_in | Network ground terminal to which all device voltages are referenced. |
| 5 | RE | input | Active-low receiver output enable; when high, the receiver output RY is placed in the high-impedance state. |
| 6 | RY | tri_state | TTL-compatible receiver output with 3-state control via RE; it is high impedance when RE is high. |
| 7 | DE | input | Active-high driver enable; when low the driver output is high impedance, with VIH min 2 V and VIL max 0.8 V. |
| 8 | VCC | power_in | Single 5 V supply, recommended 4.5 V to 5.5 V (5 V nominal) with an absolute maximum of 7 V. |
