lingxingic · Flip Flops · DIP-16

SN74HC173N from lingxingic, in a DIP-16. 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 input (active LOW); outputs are 3-state and go high-impedance when 1OE or 2OE is HIGH.
2 2OE input Output enable input (active LOW); outputs are 3-state and go high-impedance when 1OE or 2OE is HIGH.
3 Q0 tri_state 3-state flip-flop output.
4 Q1 tri_state 3-state flip-flop output.
5 Q2 tri_state 3-state flip-flop output.
6 Q3 tri_state 3-state flip-flop output.
7 CP input Clock input, LOW-to-HIGH edge triggered.
8 GND power_in Ground (0 V).
9 1E input Data enable input (active LOW).
10 2E input Data enable input (active LOW).
11 D3 input Data input.
12 D2 input Data input.
13 D1 input Data input.
14 D0 input Data input.
15 MR input Asynchronous master reset (active HIGH); clears the register.
16 VCC power_in Supply voltage; recommended 2.0 V to 6.0 V for SN74HC173 (absolute maximum 7.0 V).
