TM74HC595C

TM(Shenzhen Titan Micro Elec) · Shift Registers · SOP-16

TM74HC595C from TM(Shenzhen Titan Micro Elec), in a SOP-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 QB tri_state Three-state parallel output QB of the storage register, high-impedance when OE is high.
2 QC tri_state Three-state parallel output QC of the storage register, high-impedance when OE is high.
3 QD tri_state Three-state parallel output QD of the storage register, high-impedance when OE is high.
4 QE tri_state Three-state parallel output QE of the storage register, high-impedance when OE is high.
5 QF tri_state Three-state parallel output QF of the storage register, high-impedance when OE is high.
6 QG tri_state Three-state parallel output QG of the storage register, high-impedance when OE is high.
7 QH tri_state Three-state parallel output QH of the storage register, high-impedance when OE is high.
8 GND power_in Power supply negative terminal (ground).
9 SQH output Serial data output used to cascade the next-stage chip, with VOH of 4.18V min at IO=-4.0mA and VCC=4.5V.
10 SCLR input Active-low shift register clear input; a low level clears the shift register.
11 SCK input Shift clock input; data is shifted into the shift register on the rising edge.
12 RCK input Storage register clock input; the rising edge latches the shift register contents into the output storage register.
13 OE input Active-low output enable; high puts QA-QH in high impedance and low enables the outputs.
14 SI input Serial data input to the shift register.
15 QA tri_state Three-state parallel output QA of the storage register, high-impedance when OE is high.
16 VCC power_in Power supply positive terminal, 2.0V to 5.5V DC supply voltage.
