Texas Instruments · Counters, Dividers · SOIC-16

CD74HCT4040M96 from Texas Instruments, in a SOIC-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 Q12 output Counter stage 12 output, buffered, drives up to 10 LSTTL loads (standard output).
2 Q6 output Counter stage 6 output, buffered, drives up to 10 LSTTL loads (standard output).
3 Q5 output Counter stage 5 output, buffered, drives up to 10 LSTTL loads (standard output).
4 Q7 output Counter stage 7 output, buffered, drives up to 10 LSTTL loads (standard output).
5 Q4 output Counter stage 4 output, buffered, drives up to 10 LSTTL loads (standard output).
6 Q3 output Counter stage 3 output, buffered, drives up to 10 LSTTL loads (standard output).
7 Q2 output Counter stage 2 output, buffered, drives up to 10 LSTTL loads (standard output).
8 GND power_in Ground, 0 V reference.
9 Q1' output Counter stage 1 output (CP to Q1' path), buffered, drives up to 10 LSTTL loads (standard output).
10 CP input Clock pulse input, buffered; counter advances on each negative (high-to-low) clock transition, HCT max input frequency 25 MHz at 4.5 V.
11 MR input Master reset input; a high level resets all counter stages so all outputs go low.
12 Q9 output Counter stage 9 output, buffered, drives up to 10 LSTTL loads (standard output).
13 Q8 output Counter stage 8 output, buffered, drives up to 10 LSTTL loads (standard output).
14 Q10 output Counter stage 10 output, buffered, drives up to 10 LSTTL loads (standard output).
15 Q11 output Counter stage 11 output, buffered, drives up to 10 LSTTL loads (standard output).
16 VCC power_in Positive supply; HCT types operate from 4.5 V to 5.5 V, with a 0.1-µF bypass capacitor recommended close to the pin.
