SN74ACT241PWR

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

SN74ACT241PWR 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 Output enable 1 (active low): when 1OE is low the 1Y outputs pass the 1A data, and when 1OE is high the 1Y outputs go to the high-impedance state.
2 1A1 input Data input 1A1 of buffer channel 1; inputs are TTL-compatible and accept voltages up to 5.5 V.
3 2Y4 tri_state 3-state output 2Y4 of buffer channel 2, high-impedance when 2OE is low.
4 1A2 input Data input 1A2 of buffer channel 1; inputs are TTL-compatible and accept voltages up to 5.5 V.
5 2Y3 tri_state 3-state output 2Y3 of buffer channel 2, high-impedance when 2OE is low.
6 1A3 input Data input 1A3 of buffer channel 1; inputs are TTL-compatible and accept voltages up to 5.5 V.
7 2Y2 tri_state 3-state output 2Y2 of buffer channel 2, high-impedance when 2OE is low.
8 1A4 input Data input 1A4 of buffer channel 1; inputs are TTL-compatible and accept voltages up to 5.5 V.
9 2Y1 tri_state 3-state output 2Y1 of buffer channel 2, high-impedance when 2OE is low.
10 GND power_in Ground pin.
11 2A1 input Data input 2A1 of buffer channel 2; inputs are TTL-compatible and accept voltages up to 5.5 V.
12 1Y4 tri_state 3-state output 1Y4 of buffer channel 1, high-impedance when 1OE is high.
13 2A2 input Data input 2A2 of buffer channel 2; inputs are TTL-compatible and accept voltages up to 5.5 V.
14 1Y3 tri_state 3-state output 1Y3 of buffer channel 1, high-impedance when 1OE is high.
15 2A3 input Data input 2A3 of buffer channel 2; inputs are TTL-compatible and accept voltages up to 5.5 V.
16 1Y2 tri_state 3-state output 1Y2 of buffer channel 1, high-impedance when 1OE is high.
17 2A4 input Data input 2A4 of buffer channel 2; inputs are TTL-compatible and accept voltages up to 5.5 V.
18 1Y1 tri_state 3-state output 1Y1 of buffer channel 1, high-impedance when 1OE is high.
19 2OE input Output enable 2 (active high): when 2OE is high the 2Y outputs pass the 2A data, and when 2OE is low the 2Y outputs go to the high-impedance state.
20 VCC power_in Supply voltage, 4.5 V to 5.5 V recommended; bypass close to this pin per the datasheet guidance (0.1 µF for a single supply).
