SN74LS75DR

Texas Instruments · Latches · SOIC-16

SN74LS75DR from Texas Instruments, in a SOIC-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 1Q̅ output Complementary output of latch 1.
2 1D input Data input of latch 1, transferred to 1Q when enable 1C,2C is high.
3 2D input Data input of latch 2, transferred to 2Q when enable 1C,2C is high.
4 3C, 4C input Common enable input for latches 3 and 4; data passes when high and is retained when low.
5 VCC power_in Supply voltage; absolute maximum 7 V.
6 3D input Data input of latch 3, transferred to 3Q when enable 3C,4C is high.
7 4D input Data input of latch 4, transferred to 4Q when enable 3C,4C is high.
8 4Q̅ output Complementary output of latch 4.
9 4Q output True output of latch 4.
10 3Q output True output of latch 3.
11 3Q̅ output Complementary output of latch 3.
12 GND power_in Ground; reference terminal for voltage ratings.
13 1C, 2C input Common enable input for latches 1 and 2; data passes when high and is retained when low.
14 2Q̅ output Complementary output of latch 2.
15 2Q output True output of latch 2.
16 1Q output True output of latch 1.
