The SN74LS33N from Texas Instruments is an integrated circuit belonging to the LS technology family, designed as a quadruple 2-input positive-NOR buffer with open-collector outputs. This component contains four independent NOR gates, each requiring two inputs. The open-collector outputs necessitate a resistive pull-up for logical operation but allow for higher VOH levels, making them suitable for wired-AND applications.
Key electrical characteristics include an operating voltage range of 4.75V to 5.25V and a maximum propagation delay of 32ns at 5V with a 45pF load capacitance. The device supports a maximum data rate of 35 Mbps. The output low current (IOL) is specified at 24mA, while the output high current (IOH) is 0mA, typical for open-collector outputs. The input logic level is 2V.
Packaged in a 14-pin Dual In-line Package (PDIP) with through-hole mounting, the SN74LS33N is characterized for operation within an ambient temperature range of 0°C to 70°C. This device is suitable for various digital logic applications where NOR gating and open-collector functionality are required.
