SN74LVTH541PWR

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

SN74LVTH541PWR 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 OE1 input Active-low output enable input; all outputs are driven to high-impedance state when this input is high
2 A1 input Data input to buffer channel 1 with internal bus-hold circuitry; supports input voltage up to 5.5 V
3 A2 input Data input to buffer channel 2 with internal bus-hold circuitry; supports input voltage up to 5.5 V
4 A3 input Data input to buffer channel 3 with internal bus-hold circuitry; supports input voltage up to 5.5 V
5 A4 input Data input to buffer channel 4 with internal bus-hold circuitry; supports input voltage up to 5.5 V
6 A5 input Data input to buffer channel 5 with internal bus-hold circuitry; supports input voltage up to 5.5 V
7 A6 input Data input to buffer channel 6 with internal bus-hold circuitry; supports input voltage up to 5.5 V
8 A7 input Data input to buffer channel 7 with internal bus-hold circuitry; supports input voltage up to 5.5 V
9 A8 input Data input to buffer channel 8 with internal bus-hold circuitry; supports input voltage up to 5.5 V
10 GND power_in Ground reference, 0 V
11 Y8 tri_state Tri-state data output from buffer channel 8; high-impedance when output-enable inputs are high, otherwise drives bus line
12 Y7 tri_state Tri-state data output from buffer channel 7; high-impedance when output-enable inputs are high, otherwise drives bus line
13 Y6 tri_state Tri-state data output from buffer channel 6; high-impedance when output-enable inputs are high, otherwise drives bus line
14 Y5 tri_state Tri-state data output from buffer channel 5; high-impedance when output-enable inputs are high, otherwise drives bus line
15 Y4 tri_state Tri-state data output from buffer channel 4; high-impedance when output-enable inputs are high, otherwise drives bus line
16 Y3 tri_state Tri-state data output from buffer channel 3; high-impedance when output-enable inputs are high, otherwise drives bus line
17 Y2 tri_state Tri-state data output from buffer channel 2; high-impedance when output-enable inputs are high, otherwise drives bus line
18 Y1 tri_state Tri-state data output from buffer channel 1; high-impedance when output-enable inputs are high, otherwise drives bus line
19 OE2 input Active-low output enable input; all outputs are driven to high-impedance state when this input is high
20 VCC power_in Positive supply voltage; rated 2.7 V to 3.6 V for recommended operation
