SN74ABT241APWR

Texas Instruments · Buffers, Drivers, Receivers, Transceivers · TSSOP-20

SN74ABT241APWR from Texas Instruments, in a TSSOP-20. 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 buffers 1A1 to 1A4 (outputs 1Y1 to 1Y4); when high, the outputs go to high impedance, and it should be tied to VCC through a pullup resistor so the outputs stay high-Z during power up or power down.
2 1A1 input Data input to buffer channel 1 (drives 1Y1); unused inputs must be held high or low to prevent them from floating.
3 2Y4 tri_state Three-state output of buffer channel 4 in the 2A group (follows 2A4 when 2OE is high); high-drive output rated -32 mA IOH and 64 mA IOL.
4 1A2 input Data input to buffer channel 2 (drives 1Y2); unused inputs must be held high or low to prevent them from floating.
5 2Y3 tri_state Three-state output of buffer channel 3 in the 2A group (follows 2A3 when 2OE is high); high-drive output rated -32 mA IOH and 64 mA IOL.
6 1A3 input Data input to buffer channel 3 (drives 1Y3); unused inputs must be held high or low to prevent them from floating.
7 2Y2 tri_state Three-state output of buffer channel 2 in the 2A group (follows 2A2 when 2OE is high); high-drive output rated -32 mA IOH and 64 mA IOL.
8 1A4 input Data input to buffer channel 4 (drives 1Y4); unused inputs must be held high or low to prevent them from floating.
9 2Y1 tri_state Three-state output of buffer channel 1 in the 2A group (follows 2A1 when 2OE is high); high-drive output rated -32 mA IOH and 64 mA IOL.
10 GND power_in Ground reference for the device.
11 2A1 input Data input to buffer channel 1 of the 2A group (drives 2Y1); unused inputs must be held high or low to prevent them from floating.
12 1Y4 tri_state Three-state output of buffer channel 4 in the 1A group (follows 1A4 when 1OE is low); high-drive output rated -32 mA IOH and 64 mA IOL.
13 2A2 input Data input to buffer channel 2 of the 2A group (drives 2Y2); unused inputs must be held high or low to prevent them from floating.
14 1Y3 tri_state Three-state output of buffer channel 3 in the 1A group (follows 1A3 when 1OE is low); high-drive output rated -32 mA IOH and 64 mA IOL.
15 2A3 input Data input to buffer channel 3 of the 2A group (drives 2Y3); unused inputs must be held high or low to prevent them from floating.
16 1Y2 tri_state Three-state output of buffer channel 2 in the 1A group (follows 1A2 when 1OE is low); high-drive output rated -32 mA IOH and 64 mA IOL.
17 2A4 input Data input to buffer channel 4 of the 2A group (drives 2Y4); unused inputs must be held high or low to prevent them from floating.
18 1Y1 tri_state Three-state output of buffer channel 1 in the 1A group (follows 1A1 when 1OE is low); high-drive output rated -32 mA IOH and 64 mA IOL.
19 2OE input Output enable for buffers 2A1 to 2A4 (outputs 2Y1 to 2Y4); per the function table, outputs are enabled when this pin is high and go to high impedance when it is low.
20 VCC power_in Supply voltage, 4.5 V minimum to 5.5 V maximum recommended operating range.
