SN74LVTH126DR

Texas Instruments · Buffers, Drivers, Receivers, Transceivers · SOIC-14

SN74LVTH126DR from Texas Instruments, in a SOIC-14. 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 Output enable input for buffer 1; output is high-impedance when low
2 1A input Data input for buffer 1; TTL-compatible, input voltage 0 to 5.5V
3 1Y tri_state Three-state data output for buffer 1; follows input when 1OE is high, high-impedance when low
4 2OE input Output enable input for buffer 2; output is high-impedance when low
5 2A input Data input for buffer 2; TTL-compatible, input voltage 0 to 5.5V
6 2Y tri_state Three-state data output for buffer 2; follows input when 2OE is high, high-impedance when low
7 GND power_in Ground reference (0V)
8 3Y tri_state Three-state data output for buffer 3; follows input when 3OE is high, high-impedance when low
9 3A input Data input for buffer 3; TTL-compatible, input voltage 0 to 5.5V
10 3OE input Output enable input for buffer 3; output is high-impedance when low
11 4Y tri_state Three-state data output for buffer 4; follows input when 4OE is high, high-impedance when low
12 4A input Data input for buffer 4; TTL-compatible, input voltage 0 to 5.5V
13 4OE input Output enable input for buffer 4; output is high-impedance when low
14 VCC power_in Supply voltage, 2.7V to 3.6V recommended operating range
