74F377AD

Philips Semicons · Flip Flops · SOIC-20-300mil

74F377AD from Philips Semicons, 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 E input Active-Low enable input; it must be stable one set-up time before the Low-to-High clock transition for predictable operation.
2 Q0 output Data output of flip-flop 0; rated 50/33 U.L., with 1.0 mA high-state and 20 mA low-state current.
3 D0 input Data input of flip-flop 0; high-impedance input of 20 µA in both Low and High states (1.0/0.033 U.L.).
4 D1 input Data input of flip-flop 1; high-impedance input of 20 µA in both Low and High states (1.0/0.033 U.L.).
5 Q1 output Data output of flip-flop 1; rated 50/33 U.L., with 1.0 mA high-state and 20 mA low-state current.
6 Q2 output Data output of flip-flop 2; rated 50/33 U.L., with 1.0 mA high-state and 20 mA low-state current.
7 D2 input Data input of flip-flop 2; high-impedance input of 20 µA in both Low and High states (1.0/0.033 U.L.).
