TOSHIBA · Latches · DIP-20

TC74HC573APF from TOSHIBA, in a DIP-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 Active-low output enable input; when high the eight Q outputs are in a high-impedance state.
2 D0 input Data input 0 to the D-type latch; unused inputs must be tied to VCC or GND.
3 D1 input Data input 1 to the D-type latch; unused inputs must be tied to VCC or GND.
4 D2 input Data input 2 to the D-type latch; unused inputs must be tied to VCC or GND.
5 D3 input Data input 3 to the D-type latch; unused inputs must be tied to VCC or GND.
6 D4 input Data input 4 to the D-type latch; unused inputs must be tied to VCC or GND.
7 D5 input Data input 5 to the D-type latch; unused inputs must be tied to VCC or GND.
8 D6 input Data input 6 to the D-type latch; unused inputs must be tied to VCC or GND.
9 D7 input Data input 7 to the D-type latch; unused inputs must be tied to VCC or GND.
10 GND power_in Ground (0 V) supply pin.
11 LE input Latch enable input; Q follows D while high and outputs are latched when LE goes low.
12 Q7 tri_state 3-state latch output 7 with
13 Q6 tri_state 3-state latch output 6 with
14 Q5 tri_state 3-state latch output 5 with
