SN74LVTH573PWR

Texas Instruments · Latches · TSSOP-20

SN74LVTH573PWR 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 OE input Output Enable, active low; selects normal output state (low) or high-impedance state (high)
2 1D input Data input for first transparent latch
3 2D input Data input for second transparent latch
4 3D input Data input for third transparent latch
5 4D input Data input for fourth transparent latch
6 5D input Data input for fifth transparent latch
7 6D input Data input for sixth transparent latch
8 7D input Data input for seventh transparent latch
9 8D input Data input for eighth transparent latch
10 GND power_in Ground reference (0 V)
11 LE input Latch Enable, active high; when high Q outputs are transparent and follow D inputs, when low Q outputs latch
12 8Q tri_state Output from eighth latch; driven when OE is low, high-impedance when OE is high
13 7Q tri_state Output from seventh latch; driven when OE is low, high-impedance when OE is high
14 6Q tri_state Output from sixth latch; driven when OE is low, high-impedance when OE is high
15 5Q tri_state Output from fifth latch; driven when OE is low, high-impedance when OE is high
16 4Q tri_state Output from fourth latch; driven when OE is low, high-impedance when OE is high
17 3Q tri_state Output from third latch; driven when OE is low, high-impedance when OE is high
18 2Q tri_state Output from second latch; driven when OE is low, high-impedance when OE is high
19 1Q tri_state Output from first latch; driven when OE is low, high-impedance when OE is high
20 VCC power_in Power supply, 2.7 V to 3.6 V nominal
