DS26C32ATMX

Texas Instruments · RS-485 / RS-422 ICs · SOIC-16

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.
