SN74LVTH126PWR

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

SN74LVTH126PWR from Texas Instruments, in a TSSOP-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 Active-low output enable for buffer 1; when OE is low the 1Y output is in the high-impedance state, and it should be tied to GND through a pulldown resistor to keep the output high-impedance above 1.5 V.
2 1A input Data input of buffer 1 with active bus-hold that holds an unused or undriven input at a valid logic state, and the input accepts up to 5.5 V.
3 1Y tri_state 3-state output of buffer 1 that is high-impedance when 1OE is low and is held high-impedance during power up and power down.
4 2OE input Active-low output enable for buffer 2; when OE is low the 2Y output is in the high-impedance state.
5 2A input Data input of buffer 2 with active bus-hold that holds an unused or undriven input at a valid logic state, and the input accepts up to 5.5 V.
6 2Y tri_state 3-state output of buffer 2 that is high-impedance when 2OE is low and is held high-impedance during power up and power down.
7 GND power_in Ground reference for the device.
8 3Y tri_state 3-state output of buffer 3 that is high-impedance when 3OE is low and is held high-impedance during power up and power down.
9 3A input Data input of buffer 3 with active bus-hold that holds an unused or undriven input at a valid logic state, and the input accepts up to 5.5 V.
10 3OE input Active-low output enable for buffer 3; when OE is low the 3Y output is in the high-impedance state.
11 4Y tri_state 3-state output of buffer 4 that is high-impedance when 4OE is low and is held high-impedance during power up and power down.
12 4A input Data input of buffer 4 with active bus-hold that holds an unused or undriven input at a valid logic state, and the input accepts up to 5.5 V.
13 4OE input Active-low output enable for buffer 4; when OE is low the 4Y output is in the high-impedance state.
14 VCC power_in Supply voltage, specified from 2.7 V to 3.6 V for recommended operation.
