SN74AHC126DBR

Texas Instruments · Buffers, Drivers, Receivers, Transceivers · SSOP-14-208mil

SN74AHC126DBR from Texas Instruments, in a SSOP-14-208mil. 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 1OE input Channel 1 output enable; the Y output is in the high-impedance state when OE is low and follows A when OE is high.
2 1A input Channel 1 A input; unused inputs must be held at VCC or GND, with an input range of 0 to 5.5 V.
3 1Y output Channel 1 3-state Y output, recommended IOH/IOL of ±8 mA at VCC = 5 V ± 0.5 V.
4 2OE input Channel 2 output enable; the Y output is in the high-impedance state when OE is low and follows A when OE is high.
5 2A input Channel 2 A input; unused inputs must be held at VCC or GND, with an input range of 0 to 5.5 V.
6 2Y output Channel 2 3-state Y output, recommended IOH/IOL of ±8 mA at VCC = 5 V ± 0.5 V.
7 GND power_in Ground; continuous current through VCC or GND is limited to ±50 mA.
8 3Y output Channel 3 3-state Y output, recommended IOH/IOL of ±8 mA at VCC = 5 V ± 0.5 V.
9 3A input Channel 3 A input; unused inputs must be held at VCC or GND, with an input range of 0 to 5.5 V.
10 3OE input Channel 3 output enable; the Y output is in the high-impedance state when OE is low and follows A when OE is high.
11 4Y output Channel 4 3-state Y output, recommended IOH/IOL of ±8 mA at VCC = 5 V ± 0.5 V.
12 4A input Channel 4 A input; unused inputs must be held at VCC or GND, with an input range of 0 to 5.5 V.
13 4OE input Channel 4 output enable; the Y output is in the high-impedance state when OE is low and follows A when OE is high.
14 VCC power_in Positive supply with a recommended range of 2 V to 5.5 V and an absolute maximum of 7 V.
