SN74LV125ATDBR

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

SN74LV125ATDBR 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 Output Enable 1, active low input; output 1Y is high-impedance when this pin is high
2 1A input Data input 1A; logic level transferred to output 1Y when 1OE is low
3 1Y tri_state Tri-state output 1Y; follows input 1A when 1OE is low, high-impedance when 1OE is high
4 2OE input Output Enable 2, active low input; output 2Y is high-impedance when this pin is high
5 2A input Data input 2A; logic level transferred to output 2Y when 2OE is low
6 2Y tri_state Tri-state output 2Y; follows input 2A when 2OE is low, high-impedance when 2OE is high
7 GND power_in Ground connection
8 3Y tri_state Tri-state output 3Y; follows input 3A when 3OE is low, high-impedance when 3OE is high
9 3A input Data input 3A; logic level transferred to output 3Y when 3OE is low
10 3OE input Output Enable 3, active low input; output 3Y is high-impedance when this pin is high
11 4Y tri_state Tri-state output 4Y; follows input 4A when 4OE is low, high-impedance when 4OE is high
12 4A input Data input 4A; logic level transferred to output 4Y when 4OE is low
13 4OE input Output Enable 4, active low input; output 4Y is high-impedance when this pin is high
14 VCC power_out Positive power supply voltage; operating range 4.5 V to 5.5 V per section 5.3
