Specs side by side
2 parts compared · 14 differing specs across 14 total parameters.
| Parameter | ||
|---|---|---|
| Supply voltage | - | 3V to 15V, same drive class as the 4011B. |
| Memory & Peripherals | - | Frequently the better part for slow or noisy inputs (mechanical switches, RC edges) - the hysteresis removes contact chatter and false triggering. |
| Case | DIP-14 / SOIC-14 / TSSOP-14 | DIP-14 / SOIC-14 |
| Compatibility Level | - | Functional Equivalent |
| Component Category | CMOS Logic Gates (4000B Series) | - |
| Core & Architecture | - | Same quad 2-input NAND function in the same 4000B pin arrangement, with Schmitt-trigger inputs: each input has defined hysteresis thresholds instead of a single transition point. |
| Firmware Notes | - | Pin-for-pin with the 4011B, but not behavior-for-behavior: in oscillator and timing circuits tuned around the plain 4011 thresholds, the Schmitt thresholds shift the frequency. In debounce and slow-edge duties it is strictly better. Check which role the gate plays before swapping. |
| Hardware Notes | - | Identical 14-pin arrangement (the 4093 shares the 4011 pinout); same DIP/SOIC land patterns. |
| Lead Time Advantage | - | Shenzhen Spot Stock (24-48h Dispatch) |
| Market Reality | The CD4011B is the quad 2-input NAND of the 4000B CMOS generation - the logic of old industrial timers, alarm panels, appliance controls and instrument interlocks that are still in service and still repaired. Inside the 4000B family the pinout is a JEDEC standard, so every manufacturer copy swaps pin-for-pin. Outside the family it is a trap zone: the 74HC00 quad NAND looks like the same function in the same 14-pin body, and it is wired differently, runs on a narrower supply, and drives ten times the current. | - |
