74VHC4040FT

TOSHIBA · Counters / Dividers · TSSOP16B

74VHC4040FT from TOSHIBA, in a TSSOP16B. 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 Q12 output Counter stage 12 output (divide-by-4096 of CK). CMOS push-pull output, VOH >= VCC - 0.1 V at IOH = -50 uA; drives +/-8 mA at VCC = 4.5 V.
2 Q6 output Counter stage 6 output (divide-by-64 of CK). CMOS push-pull output driving up to +/-8 mA at VCC = 4.5 V.
3 Q5 output Counter stage 5 output (divide-by-32 of CK). CMOS push-pull output.
4 Q7 output Counter stage 7 output (divide-by-128 of CK). CMOS push-pull output.
5 Q4 output Counter stage 4 output (divide-by-16 of CK). CMOS push-pull output.
6 Q3 output Counter stage 3 output (divide-by-8 of CK). CMOS push-pull output.
7 Q2 output Counter stage 2 output (divide-by-4 of CK). CMOS push-pull output.
8 GND power_in Ground reference (0 V). Connect to system ground.
9 Q1 output Counter stage 1 output (divide-by-2 of CK). CMOS push-pull output.
10 CK input Clock input (active-low edge, negative-going transition advances the counter by one). CMOS-compatible input over 0 to 5.5 V with power-down protection.
11 CLR input Asynchronous master reset input. When held high, all Q outputs are forced low; must be low for the counter to advance on CK edges.
12 Q9 output Counter stage 9 output (divide-by-512 of CK). CMOS push-pull output.
13 Q8 output Counter stage 8 output (divide-by-256 of CK). CMOS push-pull output.
14 Q10 output Counter stage 10 output (divide-by-1024 of CK). CMOS push-pull output.
15 Q11 output Counter stage 11 output (divide-by-2048 of CK). CMOS push-pull output.
16 VCC power_in Positive supply voltage, 2.0 V to 5.5 V operating range (7.0 V absolute maximum). Bypass with a local ceramic capacitor to GND.

  • 3D model: TSSOP16B (KiCad packages3D, STEP)
  • 3D model files: 74vhc4040ft-etched.step / 74vhc4040ft-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 74vhc4040ft.step / 74vhc4040ft.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: TOSHIBA datasheet (10 pp, sha256 714d69a237bc4689, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
