CD4541BE from Texas Instruments, in a DIP-14. 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 RTC passive Timing resistor connection for RC oscillator per f=1/(2.3×RTC×CTC) with 2RTC≈CTC constraint, operating range 1kHz to 100kHz.
2 CTC passive Timing capacitor connection for RC oscillator per f=1/(2.3×RTC×CTC) with 2RTC≈CTC constraint, operating range 1kHz to 100kHz.
3 RS input Series resistor connection for RC oscillator (RS ≥ 10kΩ minimum) that alternatively accepts external clock input DC to 100kHz instead of internal oscillator.
4 NC unconnected No connection.
5 AUTO RESET input Automatic reset input active low; logic 0 enables auto power-on reset circuit (requires VDD > 5V for reliable operation), logic 1 disables auto reset requiring positive MASTER RESET pulse to start counting.
6 MASTER RESET input Manual reset input active high; positive pulse resets 16-stage binary counter and output latch to high level; circuit is retriggerable.
7 VSS power_in Ground; negative power supply reference at 0V for all digital logic levels.
8 OUTPUT output Programmable frequency divider output selecting Q from counter stage selected by A/B inputs (8/10/13/16-stage); provides continuous f=fosc/2^N square wave at MODE=1 or single-transition pulse output at MODE=0.
9 Q/Q SELECT input Output polarity select input; logic 0 selects Q output initially low after reset, logic 1 selects Q̄ output initially high after reset.
10 MODE input Mode select input; logic 0 enables single-transition timer mode with output pulse after 2^(N-1) clock counts, logic 1 enables recycle mode with continuous f=fosc/2^N square wave output.
11 NC unconnected No connection.
12 A input Frequency select input A; combined with B input selects counter stage for frequency division factor: (A,B)=(0,0)→13-stage/8192, (0,1)→10-stage/1024, (1,0)→8-stage/256, (1,1)→16-stage/65536.
13 B input Frequency select input B; combined with A input selects counter stage for frequency divider ratio per frequency selection table.
14 VDD power_in Positive power supply; operating voltage 3V minimum to 18V typical, with 20V absolute maximum rating per JEDEC specification.
