SN74LVC573AQDWRQ1

Texas Instruments · Latches · SOIC-20-300mil

SN74LVC573AQDWRQ1 from Texas Instruments, in a SOIC-20-300mil. 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 OE input Buffered output-enable input (active low); when low, outputs follow latch state; when high, all outputs are high-impedance
2 1D input Data input for latch 1; sampled when LE transitions from high to low
3 2D input Data input for latch 2; sampled when LE transitions from high to low
4 3D input Data input for latch 3; sampled when LE transitions from high to low
5 4D input Data input for latch 4; sampled when LE transitions from high to low
6 5D input Data input for latch 5; sampled when LE transitions from high to low
7 6D input Data input for latch 6; sampled when LE transitions from high to low
8 7D input Data input for latch 7; sampled when LE transitions from high to low
9 8D input Data input for latch 8; sampled when LE transitions from high to low
10 GND power_in Ground; negative supply rail (0 V reference)
11 LE input Latch-enable input; when high, Q outputs follow D inputs; when low, Q outputs latch current D input state
12 8Q tri_state 3-state output for latch 8; active high/low when OE=low, high-impedance when OE=high
13 7Q tri_state 3-state output for latch 7; active high/low when OE=low, high-impedance when OE=high
14 6Q tri_state 3-state output for latch 6; active high/low when OE=low, high-impedance when OE=high
15 5Q tri_state 3-state output for latch 5; active high/low when OE=low, high-impedance when OE=high
16 4Q tri_state 3-state output for latch 4; active high/low when OE=low, high-impedance when OE=high
17 3Q tri_state 3-state output for latch 3; active high/low when OE=low, high-impedance when OE=high
18 2Q tri_state 3-state output for latch 2; active high/low when OE=low, high-impedance when OE=high
19 1Q tri_state 3-state output for latch 1; active high/low when OE=low, high-impedance when OE=high
20 VCC power_in Supply voltage; positive supply rail (2.7 V to 3.6 V operating range)
