XINLUDA · Registers · DIP-16

XD74LS165 from XINLUDA, 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 SH/LD input Shift/load input: while SH/LD is low, parallel data at A to H is loaded directly into the register independent of CLK, CLK INH, or SER, and parallel loading is inhibited while it is high (Req = 13 kΩ NOM).
2 CLK input Gated clock input: clocking is inhibited while held high, and with SH/LD high it is enabled when CLK INH is held low; the datasheet gives a clock frequency range of 0 to 25 MHz and a minimum clock-high pulse width of 15 ns.
3 E input Parallel data input for the fifth register stage, loaded when SH/LD is low; parallel input setup time is 10 ns minimum.
4 F input Parallel data input for the sixth register stage, loaded when SH/LD is low; parallel input setup time is 10 ns minimum.
5 G input Parallel data input for the seventh register stage, loaded when SH/LD is low; parallel input setup time is 10 ns minimum.
6 H input Parallel data input for the eighth register stage, loaded when SH/LD is low; parallel input setup time is 10 ns minimum.
7 QH output Eighth-bit serial output of the register; the datasheet specifies IOL of 8 mA maximum and IOH of -0.4 mA, with VOH of 2.7 V minimum.
8 GND power_in Ground reference for the device (network ground terminal).
9 QH output Complementary output of the eighth bit (QH), provided alongside QH.
10 SER input Serial data input to the first register stage (QA), shifted toward QH on the clock; serial input setup time is 20 ns minimum.
11 A input Parallel data input for the first register stage, loaded when SH/LD is low; parallel input setup time is 10 ns minimum.
12 B input Parallel data input for the second register stage, loaded when SH/LD is low; parallel input setup time is 10 ns minimum.
13 C input Parallel data input for the third register stage, loaded when SH/LD is low; parallel input setup time is 10 ns minimum.
14 D input Parallel data input for the fourth register stage, loaded when SH/LD is low; parallel input setup time is 10 ns minimum.
15 CLK INH input Clock inhibit input: holding it high inhibits clocking, and it should be changed to the high level only while CLK is high.
16 VCC power_in Supply voltage, 4.75 V minimum, 5 V nominal, 5.25 V maximum per the recommended operating conditions.
