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

AM26LV31ESDREP 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 Data input for channel 1; accepts 0-5.5 V logic levels with 3.3-V supply, VIH ≥ 2 V, VIL ≤ 0.8 V, input current ±10 µA max.
2 1Y tri_state Non-inverting 3-state differential output of channel 1; VOH ≥ 2.4 V at IOH = −20 mA, VOL ≤ 0.4 V at IOL = 20 mA, high-impedance when disabled.
3 1Z tri_state Inverting 3-state differential output of channel 1; VOH ≥ 2.4 V at IOH = −20 mA, VOL ≤ 0.4 V at IOL = 20 mA, ±15-kV HBM ESD protection on bus pin.
4 G input Active-high output enable shared by all four channels; G = H enables outputs, G = L forces all Y/Z outputs to high impedance; VIH ≥ 2 V, VIL ≤ 0.8 V.
5 2Z tri_state Inverting 3-state differential output of channel 2; VOH ≥ 2.4 V at IOH = −20 mA, VOL ≤ 0.4 V at IOL = 20 mA, ±15-kV HBM ESD protection on bus pin.
6 2Y tri_state Non-inverting 3-state differential output of channel 2; VOH ≥ 2.4 V at IOH = −20 mA, VOL ≤ 0.4 V at IOL = 20 mA, high-impedance when disabled.
7 2A input Data input for channel 2; accepts 0-5.5 V logic levels with 3.3-V supply, VIH ≥ 2 V, VIL ≤ 0.8 V, input current ±10 µA max.
8 GND power_in Ground reference (0 V) for all internal circuitry; continuous current through GND pin up to ±200 mA absolute maximum.
9 3A input Data input for channel 3; accepts 0-5.5 V logic levels with 3.3-V supply, VIH ≥ 2 V, VIL ≤ 0.8 V, input current ±10 µA max.
10 3Y tri_state Non-inverting 3-state differential output of channel 3; VOH ≥ 2.4 V at IOH = −20 mA, VOL ≤ 0.4 V at IOL = 20 mA, high-impedance when disabled.
11 3Z tri_state Inverting 3-state differential output of channel 3; VOH ≥ 2.4 V at IOH = −20 mA, VOL ≤ 0.4 V at IOL = 20 mA, ±15-kV HBM ESD protection on bus pin.
12 /G input Active-low output enable shared by all four channels; /G = L enables outputs, /G = H forces all Y/Z outputs to high impedance; VIH ≥ 2 V, VIL ≤ 0.8 V.
13 4Z tri_state Inverting 3-state differential output of channel 4; VOH ≥ 2.4 V at IOH = −20 mA, VOL ≤ 0.4 V at IOL = 20 mA, ±15-kV HBM ESD protection on bus pin.
14 4Y tri_state Non-inverting 3-state differential output of channel 4; VOH ≥ 2.4 V at IOH = −20 mA, VOL ≤ 0.4 V at IOL = 20 mA, high-impedance when disabled.
15 4A input Data input for channel 4; accepts 0-5.5 V logic levels with 3.3-V supply, VIH ≥ 2 V, VIL ≤ 0.8 V, input current ±10 µA max.
16 VCC power_in Positive supply voltage; recommended operating range 3.0 V to 3.6 V (nominal 3.3 V), absolute maximum 6 V, quiescent supply current 100 µA typ (no load, enabled).
