SN74ALS33A is Quadruple 2-Input Positive-NOR Buffers manufactured by Texas Instruments.
| Part Number | Description |
|---|---|
| SN74ALS30A | 8-INPUT POSITIVE-NAND GATES |
| SN74ALS30AN | 8-INPUT POSITIVE-NAND GATES |
| SN74ALS32 | Quadruple 2-Input Positive-OR Gates |
| SN74ALS323 | 8-Bit Universal Shift/Storage Registers |
| SN74ALS35A | Hex Noninverter |
These devices contain four independent 2-input positive-NOR buffers with open-collector outputs. Open-collector outputs require resistive pullup to perform correctly. They can deliver higher VOH levels and monly are used in wired-AND applications.
