DS26C32ATMX from Texas Instruments, in a SOIC-16. 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 | -IN A | input | Inverting differential input of receiver channel A; input resistance 5.0-11 kΩ and common-mode range ±7V per the input sensitivity spec, with an input voltage rating up to ±14V absolute maximum. |
| 2 | +IN A | input | Non-inverting differential input of receiver channel A, differential input voltage sensitivity is ±0.2V (200 mV) over the common-mode range with typical hysteresis of 60 mV. |
| 3 | OUTPUT A | tri_state | TRI-STATE output of receiver channel A capable of sourcing 6 mA (VOH ≥ 3.8V min) and sinking 6 mA (VOL ≤ 0.3V max), controlled by ENABLE (pin 4). |
| 4 | ENABLE | input | Active-high enable input common to receivers A and C; VIH ≥ 2.0V enables the outputs and VIL ≤ 0.8V forces them to TRI-STATE, with max input current ±1.0 µA. |
| 5 | OUTPUT C | tri_state | TRI-STATE output of receiver channel C, sourcing 6 mA / sinking 6 mA with the same VOH/VOL limits as the other receiver outputs, controlled by ENABLE (pin 4). |
| 6 | +IN C | input | Non-inverting differential input of receiver channel C with ±0.2V input sensitivity over the ±7V common-mode input voltage range. |
| 7 | -IN C | input | Inverting differential input of receiver channel C; input resistance 5.0-11 kΩ depending on grade, with pull-up/pull-down bias that keeps outputs from oscillating when unused. |
| 8 | GND | power_in | Ground reference pin for the device; all voltages are referenced to this pin. |
| 9 | -IN D | input | Inverting differential input of receiver channel D; inputs do not load the line even when VCC = 0V. |
| 10 | +IN D | input | Non-inverting differential input of receiver channel D with ±0.2V sensitivity over the ±7V common-mode voltage range. |
| 11 | OUTPUT D | tri_state | TRI-STATE output of receiver channel D, sourcing 6 mA / sinking 6 mA with VOH/VOL limits per the DC electrical characteristics, controlled by ENABLE-bar (pin 12). |
| 12 | ENABLE-bar | input | Active-low enable input common to receivers B and D; a logic low enables the outputs and a logic high forces them to TRI-STATE, VIH/VIL thresholds of 2.0V/0.8V apply. |
| 13 | OUTPUT B | tri_state | TRI-STATE output of receiver channel B, sourcing 6 mA / sinking 6 mA with the same VOH/VOL limits as the other outputs, controlled by ENABLE-bar (pin 12). |
| 14 | +IN B | input | Non-inverting differential input of receiver channel B with ±0.2V differential sensitivity over the ±7V input common-mode range. |
| 15 | -IN B | input | Inverting differential input of receiver channel B; absolute maximum differential input voltage is ±14V. |
| 16 | VCC | power_in | Positive supply pin, operating range 4.50V to 5.50V, with quiescent supply current of 16 mA typical / 23 mA max (DS26C32AT) at VCC = max. |
