SN74LVTH125DR

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

SN74LVTH125DR 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; drives output 1Y to high-impedance state when high.
2 1A input Data input for buffer 1; drives output 1Y when buffer is enabled.
3 1Y tri_state Data output for buffer 1; high-impedance when 1OE is high, otherwise follows 1A.
4 2OE input Output-enable input for buffer 2; drives output 2Y to high-impedance state when high.
5 2A input Data input for buffer 2; drives output 2Y when buffer is enabled.
6 2Y tri_state Data output for buffer 2; high-impedance when 2OE is high, otherwise follows 2A.
7 GND power_in Ground, 0 V reference.
8 3Y tri_state Data output for buffer 3; high-impedance when 3OE is high, otherwise follows 3A.
9 3A input Data input for buffer 3; drives output 3Y when buffer is enabled.
10 3OE input Output-enable input for buffer 3; drives output 3Y to high-impedance state when high.
11 4Y tri_state Data output for buffer 4; high-impedance when 4OE is high, otherwise follows 4A.
12 4A input Data input for buffer 4; drives output 4Y when buffer is enabled.
13 4OE input Output-enable input for buffer 4; drives output 4Y to high-impedance state when high.
14 VCC power_in Supply voltage input; 2.7 V to 3.6 V recommended for SN74LVTH125.
