SN75158PSR from Texas Instruments, in a SOIC-8-208mil. 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 | 1Z | output | Inverting output of the differential driver on channel 1; TTL totem-pole output that is high impedance when the device is powered off, rated for IOH of -40 mA and IOL of 40 mA. |
| 2 | 1Y | output | Non-inverting output of the differential driver on channel 1; TTL totem-pole output that is high impedance when the device is powered off, rated for IOH of -40 mA and IOL of 40 mA. |
| 3 | 1A | input | Single-ended data input for channel 1; VIH minimum 2 V and VIL maximum 0.8 V. |
| 4 | GND | power_in | Device ground, the network ground reference for all voltages. |
| 5 | 2A | input | Single-ended data input for channel 2; VIH minimum 2 V and VIL maximum 0.8 V. |
| 6 | 2Y | output | Non-inverting output of the differential driver on channel 2; TTL totem-pole output that is high impedance when the device is powered off, rated for IOH of -40 mA and IOL of 40 mA. |
| 7 | 2Z | output | Inverting output of the differential driver on channel 2; TTL totem-pole output that is high impedance when the device is powered off, rated for IOH of -40 mA and IOL of 40 mA. |
| 8 | VCC | power_in | 5 V power supply positive terminal; recommended supply range 4.75 V to 5.25 V, absolute maximum 7 V. |
