CD74HCT75M

Texas Instruments · Latches · SOIC-16

CD74HCT75M 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 1Q0̅ output Complementary output of latch 0 of the first 2-bit latch; drives 10 LSTTL loads (standard output).
2 1D0 input Data input 0 of the first latch (HCT: VIH 2V min, VIL 0.8V max, 0.8 unit load).
3 1D1 input Data input 1 of the first latch (HCT: VIH 2V min, VIL 0.8V max, 0.8 unit load).
4 2E input Enable input for the second 2-bit latch; data enters the latch and appears at Q when E is HIGH, output is not affected when LOW (1.2 unit loads).
5 VCC power_in Supply voltage, 4.5V to 5.5V for HCT types (absolute maximum -0.5V to 7V).
6 2D0 input Data input 0 of the second latch (HCT: VIH 2V min, VIL 0.8V max, 0.8 unit load).
7 2D1 input Data input 1 of the second latch (HCT: VIH 2V min, VIL 0.8V max, 0.8 unit load).
8 2Q1̅ output Complementary output of latch 1 of the second 2-bit latch; drives 10 LSTTL loads (standard output).
9 2Q1 output True output of latch 1 of the second 2-bit latch; drives 10 LSTTL loads (standard output).
10 2Q0 output True output of latch 0 of the second 2-bit latch; drives 10 LSTTL loads (standard output).
11 2Q0̅ output Complementary output of latch 0 of the second 2-bit latch; drives 10 LSTTL loads (standard output).
12 GND power_in Ground (0V reference); DC VCC or ground current limit is ±50mA.
13 1E input Enable input for the first 2-bit latch; data enters the latch and appears at Q when E is HIGH, output is not affected when LOW (1.2 unit loads).
14 1Q1̅ output Complementary output of latch 1 of the first 2-bit latch; drives 10 LSTTL loads (standard output).
15 1Q1 output True output of latch 1 of the first 2-bit latch; drives 10 LSTTL loads (standard output).
16 1Q0 output True output of latch 0 of the first 2-bit latch; drives 10 LSTTL loads (standard output).
