DS26C32ATM

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

DS26C32ATM 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 A, with ±0.2V sensitivity over the ±7V common-mode range.
2 +IN A input Non-inverting differential input of receiver A, with ±0.2V sensitivity over the ±7V common-mode range.
3 OUT A tri_state TRI-STATE output of receiver A with 6 mA source and sink capability.
4 ENABLE input Active-high enable common to all four receivers; outputs are TRI-STATE when ENABLE is low and ENABLE (bar) is high, with VIH min 2.0V and VIL max 0.8V.
5 OUT C tri_state TRI-STATE output of receiver C with 6 mA source and sink capability.
6 +IN C input Non-inverting differential input of receiver C, with ±0.2V sensitivity over the ±7V common-mode range.
7 -IN C input Inverting differential input of receiver C, with ±0.2V sensitivity over the ±7V common-mode range.
8 GND power_in Ground reference for the device.
9 -IN D input Inverting differential input of receiver D, with ±0.2V sensitivity over the ±7V common-mode range.
10 +IN D input Non-inverting differential input of receiver D, with ±0.2V sensitivity over the ±7V common-mode range.
11 OUT D tri_state TRI-STATE output of receiver D with 6 mA source and sink capability.
12 ENABLE̅ input Active-low enable common to all four receivers; outputs are TRI-STATE when ENABLE is low and this pin is high, with VIH min 2.0V and VIL max 0.8V.
13 OUT B tri_state TRI-STATE output of receiver B with 6 mA source and sink capability.
14 +IN B input Non-inverting differential input of receiver B, with ±0.2V sensitivity over the ±7V common-mode range.
15 -IN B input Inverting differential input of receiver B, with ±0.2V sensitivity over the ±7V common-mode range.
16 VCC power_in Positive supply, 4.50V to 5.50V recommended operating range (7V absolute maximum).
