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).
