AM26C31IDBR

Texas Instruments · RS-485 / RS-422 ICs · SSOP-16-208mil

AM26C31IDBR from Texas Instruments, in a SSOP-16-208mil. 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 1A input Driver 1 input.
2 1Y output Driver 1 output (non-inverted side of the differential pair).
3 1Z output Driver 1 inverted output (complementary side of the differential pair).

5 2Z output Driver 2 inverted output (complementary side of the differential pair).
6 2Y output Driver 2 output (non-inverted side of the differential pair).
7 2A input Driver 2 input.
8 GND power_in Ground pin (network ground reference for all voltages in the Absolute Maximum Ratings).
9 3A input Driver 3 input.
10 3Y output Driver 3 output (non-inverted side of the differential pair).
11 3Z output Driver 3 inverted output (complementary side of the differential pair).
12 G input Active-low enable input for drivers 3 and 4 (the G pin at pin 12 is the active-low enable per Table 4-1).
13 4Z output Driver 4 inverted output (complementary side of the differential pair).
14 4Y output Driver 4 output (non-inverted side of the differential pair).
15 4A input Driver 4 input.
16 VCC power_in Supply pin; recommended supply is 4.5 V to 5.5 V (5 V nominal), absolute maximum 7 V.
