74LVC595APW

Nexperia · Shifting Register · TSSOP-16

74LVC595APW from Nexperia, in a TSSOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Q1 output Parallel data output bit 1 from the 8-bit storage register. 3-state; driven when OE is LOW, high-impedance when OE is HIGH. Drive capability up to ±24 mA at VCC = 3.0 V.
2 Q2 output Parallel data output bit 2 from the 8-bit storage register. 3-state output controlled by OE.
3 Q3 output Parallel data output bit 3 from the 8-bit storage register. 3-state output controlled by OE.
4 Q4 output Parallel data output bit 4 from the 8-bit storage register. 3-state output controlled by OE.
5 Q5 output Parallel data output bit 5 from the 8-bit storage register. 3-state output controlled by OE.
6 Q6 output Parallel data output bit 6 from the 8-bit storage register. 3-state output controlled by OE.
7 Q7 output Parallel data output bit 7 (MSB) from the 8-bit storage register. 3-state output controlled by OE.
8 GND power_in Ground reference (0 V). Return for all supply and signal currents.
9 Q7S output Serial data output taken from the last (8th) stage of the shift register. Used to cascade multiple 74LVC595A devices; connect to DS of the next stage. Not 3-stated by OE.
10 MR input Master reset, active LOW. A LOW on MR asynchronously clears the shift register only; the storage register contents (Qn) are unaffected until STCP is toggled. Schmitt-trigger input.
11 SHCP input Shift register clock input. Data on DS is shifted into the shift register on the LOW-to-HIGH transition of SHCP. Schmitt-trigger input; fmax up to 130 MHz min at VCC = 3.0-3.6 V.
12 STCP input Storage register clock input (latch). LOW-to-HIGH transition transfers the contents of the shift register to the 8-bit storage register that drives Q0-Q7. Schmitt-trigger input.
13 OE input Output enable, active LOW. LOW enables the Q0-Q7 parallel outputs; HIGH places them in high-impedance (3-state) OFF-state. Does not affect the state of the internal registers or Q7S. Schmitt-trigger input.
14 DS input Serial data input. Data present on DS is loaded into shift-register stage 0 on the LOW-to-HIGH transition of SHCP. Schmitt-trigger input; setup time ~2 ns typical at VCC = 3.0-3.6 V.
15 Q0 output Parallel data output bit 0 (LSB) from the 8-bit storage register. 3-state output controlled by OE.
16 VCC power_in Supply voltage. Operating range 1.65 V to 3.6 V (functional down to 1.2 V); overvoltage-tolerant inputs to 5.5 V allow use as a 3.3 V ↔ 5 V level translator. Absolute maximum 6.5 V.
