Texas Instruments · Buffers, Drivers, Receivers, Transceivers · SOIC-16

AM26C31QDR 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 input; accepts logic signals with recommended levels 0.8V to 2.0V.
2 1Y tri_state Driver 1 complementary output; tri-state with minimum VOH = 2.2V and maximum VOL = 0.4V at -40 to +125°C.
3 1Z tri_state Driver 1 inverted output; tri-state with minimum VOH = 2.2V and maximum VOL = 0.4V at -40 to +125°C.
4 G input Active high enable input for Drivers 1 and 2; enables outputs when VIH ≥ 2.0V.
5 2Z tri_state Driver 2 inverted output; tri-state with minimum VOH = 2.2V and maximum VOL = 0.4V at -40 to +125°C.
6 2Y tri_state Driver 2 complementary output; tri-state with minimum VOH = 2.2V and maximum VOL = 0.4V at -40 to +125°C.
7 2A input Driver 2 input; accepts logic signals with recommended levels 0.8V to 2.0V.
8 GND power_in Ground pin; network ground terminal for voltage reference.
9 3A input Driver 3 input; accepts logic signals with recommended levels 0.8V to 2.0V.
10 3Y tri_state Driver 3 complementary output; tri-state with minimum VOH = 2.2V and maximum VOL = 0.4V at -40 to +125°C.
11 3Z tri_state Driver 3 inverted output; tri-state with minimum VOH = 2.2V and maximum VOL = 0.4V at -40 to +125°C.
12 G input Active low enable input for Drivers 3 and 4; enables outputs when VIL ≤ 0.8V.
13 4Z tri_state Driver 4 inverted output; tri-state with minimum VOH = 2.2V and maximum VOL = 0.4V at -40 to +125°C.
14 4Y tri_state Driver 4 complementary output; tri-state with minimum VOH = 2.2V and maximum VOL = 0.4V at -40 to +125°C.
15 4A input Driver 4 input; accepts logic signals with recommended levels 0.8V to 2.0V.
16 VCC power_in Power pin; supply voltage range 4.5V to 5.5V for single 5V supply operation.
