Texas Instruments · Buffers, Drivers, Receivers, Transceivers · SSOP-20-208mil

SN74ABT2244ADBR from Texas Instruments, in a SSOP-20-208mil. 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 Active-low output enable for buffer group 1 (1Y1-1Y4); high puts outputs in high-impedance state.
2 1A1 input Data input A1 of group 1, drives 1Y1 (pin 18); unused inputs must be held high or low.
3 2Y4 output 3-state output Y4 of group 2 with equivalent 25-ohm series resistor, follows 2A4; sinks up to 12 mA.
4 1A2 input Data input A2 of group 1, drives 1Y2 (pin 16); unused inputs must be held high or low.
5 2Y3 output 3-state output Y3 of group 2 with equivalent 25-ohm series resistor, follows 2A3; sinks up to 12 mA.
6 1A3 input Data input A3 of group 1, drives 1Y3 (pin 14); unused inputs must be held high or low.
7 2Y2 output 3-state output Y2 of group 2 with equivalent 25-ohm series resistor, follows 2A2; sinks up to 12 mA.
8 1A4 input Data input A4 of group 1, drives 1Y4 (pin 12); unused inputs must be held high or low.
9 2Y1 output 3-state output Y1 of group 2 with equivalent 25-ohm series resistor, follows 2A1; sinks up to 12 mA.
10 GND power_in Ground.
11 2A1 input Data input A1 of group 2, drives 2Y1 (pin 9); unused inputs must be held high or low.
12 1Y4 output 3-state output Y4 of group 1 with equivalent 25-ohm series resistor, follows 1A4; sinks up to 12 mA.
13 2A2 input Data input A2 of group 2, drives 2Y2 (pin 7); unused inputs must be held high or low.
14 1Y3 output 3-state output Y3 of group 1 with equivalent 25-ohm series resistor, follows 1A3; sinks up to 12 mA.
15 2A3 input Data input A3 of group 2, drives 2Y3 (pin 5); unused inputs must be held high or low.
16 1Y2 output 3-state output Y2 of group 1 with equivalent 25-ohm series resistor, follows 1A2; sinks up to 12 mA.
17 2A4 input Data input A4 of group 2, drives 2Y4 (pin 3); unused inputs must be held high or low.
18 1Y1 output 3-state output Y1 of group 1 with equivalent 25-ohm series resistor, follows 1A1; sinks up to 12 mA.
19 2OE input Active-low output enable for buffer group 2 (2Y1-2Y4); high puts outputs in high-impedance state.
20 VCC power_in Supply voltage, 4.5 V to 5.5 V recommended (absolute maximum -0.5 V to 7 V).
