AM26C31MDREP

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

AM26C31MDREP 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 1A input Driver 1 logic input; high-level input voltage min 2 V, low-level max 0.8 V.
2 1Y tri_state Driver 1 non-inverting 3-state output, rated for IOH of -20 mA and IOL of 20 mA, high-impedance when disabled or powered off.
3 1Z tri_state Driver 1 complementary (inverting) 3-state output, rated for IOH of -20 mA and IOL of 20 mA, high-impedance when disabled or powered off.
4 G input Active-high enable input common to all four drivers; outputs are active when G is high.
5 2Z tri_state Driver 2 complementary (inverting) 3-state output, rated for IOH of -20 mA and IOL of 20 mA, high-impedance when disabled or powered off.
6 2Y tri_state Driver 2 non-inverting 3-state output, rated for IOH of -20 mA and IOL of 20 mA, high-impedance when disabled or powered off.
7 2A input Driver 2 logic input; high-level input voltage min 2 V, low-level max 0.8 V.
8 GND power_in Ground terminal, the reference for all voltage values.
9 3A input Driver 3 logic input; high-level input voltage min 2 V, low-level max 0.8 V.
10 3Y tri_state Driver 3 non-inverting 3-state output, rated for IOH of -20 mA and IOL of 20 mA, high-impedance when disabled or powered off.
11 3Z tri_state Driver 3 complementary (inverting) 3-state output, rated for IOH of -20 mA and IOL of 20 mA, high-impedance when disabled or powered off.
12 G̅ input Active-low enable input common to all four drivers; outputs are active when this pin is low.
13 4Z tri_state Driver 4 complementary (inverting) 3-state output, rated for IOH of -20 mA and IOL of 20 mA, high-impedance when disabled or powered off.
14 4Y tri_state Driver 4 non-inverting 3-state output, rated for IOH of -20 mA and IOL of 20 mA, high-impedance when disabled or powered off.
15 4A input Driver 4 logic input; high-level input voltage min 2 V, low-level max 0.8 V.
16 VCC power_in Supply voltage, 4.5 V to 5.5 V recommended (5 V nominal), absolute maximum 7 V.
