Diodes Incorporated · Registers · TSSOP-16

74AHC595T16-13 from Diodes Incorporated, in a TSSOP-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 Q1 tri_state Parallel 3-state data output 1, active when OE is asserted low.
2 Q2 tri_state Parallel 3-state data output 2, active when OE is asserted low.
3 Q3 tri_state Parallel 3-state data output 3, active when OE is asserted low.
4 Q4 tri_state Parallel 3-state data output 4, active when OE is asserted low.
5 Q5 tri_state Parallel 3-state data output 5, active when OE is asserted low.
6 Q6 tri_state Parallel 3-state data output 6, active when OE is asserted low.
7 Q7 tri_state Parallel 3-state data output 7, active when OE is asserted low.
8 GND power_in Ground reference for the device.
9 Q7S output Serial data output; the content of Q6S is shifted to Q7S and appears on this pin.
10 MR input Master reset input; when asserted low it sets all shift register values to zero and is independent of all clocks.
11 SHCP input Shift register clock input; data on DS is shifted in on each positive transition of this clock.
12 STCP input Storage register clock input; a rising pulse transfers the shift register contents to the output register.
13 OE input Output enable input; the 3-state outputs Q0-Q7 become active when asserted low.
14 DS input Serial data input, captured on each positive transition of the shift register clock.
15 Q0 tri_state Parallel 3-state data output 0, active when OE is asserted low.
16 VCC power_in Supply voltage, recommended range 2.0 V to 5.5 V.
