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 terminal for the internal RC oscillator; used with CTC (and RS) to set oscillator frequency per f = 1/(2.3·RTC·CTC), valid for f between 1kHz and 100kHz. |+| 2 | CTC | passive | Timing capacitor terminal for the internal RC oscillator; used with RTC to set the oscillator frequency (1kHz to 100kHz range). |+| 3 | RS | passive | Oscillator bias resistor terminal (RS ≥ 10kΩ, 2·RTC ≈ RS per oscillator equation); this pin can alternatively accept an external clock input in place of the internal oscillator. |+| 4 | NC | unconnected | No internal connection. |+| 5 | AUTO RESET | input | Logic 0 enables Auto Reset so counting starts automatically on power-up (recommended VDD > 5V for reliable auto reset); logic 1 disables Auto Reset, requiring a positive Master Reset pulse to start counting; enabling this input draws additional supply current. |+| 6 | MASTER RESET | input | A positive pulse on this input resets the internal counter and output latch; logic 0 = Master Reset off, logic 1 = Master Reset on. |+| 7 | VSS | power_in | Negative supply / ground reference terminal; all other pin voltages are referenced to VSS. |+| 8 | OUTPUT | output | Q or Q output taken from the selected counter stage (8th, 10th, 13th, or 16th stage as chosen by A and B); capable of driving six Low-Power TTL loads, three Low-Power Schottky loads, or six HTL loads over the rated temperature range. |+| 9 | Q/Q SELECT | input | Selects output polarity after reset: logic 0 gives output initially low after reset (Q), logic 1 gives output initially high after reset (Q̄). |+| 10 | MODE | input | Logic 1 sets Recycle mode, producing a continuous square wave at the oscillator frequency divided by 2^N; logic 0 sets Single-Transition mode, where the output changes state once after 2^(N-1) counts following a Master Reset. |+| 11 | NC | unconnected | No internal connection. |+| 12 | A | input | Time-select input A; used with input B to select the counter output stage per the Frequency Selection Table (e.g., A=0,B=0 selects N=13, count 8192). |+| 13 | B | input | Time-select input B; used with input A to select the counter output stage per the Frequency Selection Table (e.g., A=1,B=1 selects N=16, count 65536). |+| 14 | VDD | power_in | Positive supply voltage; operating range 3V (min) to 18V (typ) over the full temperature range, absolute maximum -0.5V to +20V referenced to VSS. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | TSSOP-14 |+| Category | Clock/Timing |+| Pins | 14 |++## CAD (KiCad official)++- Symbol: `CD4541BPWR`+- Footprint: `Package_SO:TSSOP-14_4.4x5mm_P0.65mm`+- 3D model: TSSOP-14 (KiCad packages3D, STEP)+- 3D model files: `cd4541bpwr-etched.step` / `cd4541bpwr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `cd4541bpwr.step` / `cd4541bpwr.glb` are the bare package body.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/cd4541b.pdf) (22 pp, sha256 `1c648629cd0ba6ed`, retrieved 2026-09-23, tier: manufacturer)+- **Extractor:** parts-factory `2.0.0` / `extract_pins 0.2`, primary `claude-haiku-4-5-20251001` (text), consensus `claude-sonnet-5` (agreed), guards: pin_guards 0.1: passed.
