CD74HC4520M96

Texas Instruments · Counters, Dividers · SOIC-16

CD74HC4520M96 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 1CP input Counter 1 clock input, increments counter on positive-going or negative-going edge transitions when enabled.
2 1E input Counter 1 enable input, logic high enables counter increment on clock transitions, logic low disables.
3 1Q0 output Counter 1 output bit 0 (least significant bit), resets to logic low when 1MR is high.
4 1Q1 output Counter 1 output bit 1, resets to logic low when 1MR is high.
5 1Q2 output Counter 1 output bit 2, resets to logic low when 1MR is high.
6 1Q3 output Counter 1 output bit 3 (most significant bit), resets to logic low when 1MR is high.
7 1MR input Counter 1 master reset input, high level forces all counter outputs Q0-Q3 to logic low.
8 GND power_in Ground, 0V power supply reference.
9 2CP input Counter 2 clock input, increments counter on positive-going or negative-going edge transitions when enabled.
10 2E input Counter 2 enable input, logic high enables counter increment on clock transitions, logic low disables.
11 2Q0 output Counter 2 output bit 0 (least significant bit), resets to logic low when 2MR is high.
12 2Q1 output Counter 2 output bit 1, resets to logic low when 2MR is high.
13 2Q2 output Counter 2 output bit 2, resets to logic low when 2MR is high.
14 2Q3 output Counter 2 output bit 3 (most significant bit), resets to logic low when 2MR is high.
15 2MR input Counter 2 master reset input, high level forces all counter outputs Q0-Q3 to logic low.
16 VCC power_in Power supply input, positive voltage 2V to 6V for HC types, 4.5V to 5.5V for HCT types.
