SN74LS33DR Description

Short technical summary and product information.

The SN74LS33DR from Texas Instruments is a logic IC featuring four independent 2-input NOR buffer gates. These gates are characterized by their open-collector outputs, which require a resistive pull-up for logical operation but can achieve higher VOH levels, making them suitable for wired-AND applications.

 

This component operates within a supply voltage range of 4.75V to 5.25V and has a maximum output current of 24mA. The propagation delay is specified at 32ns at 5V with a 45pF load, and it supports data rates up to 35Mbps. The device is designed for high-speed operation, with propagation delays typically between 10ns and 50ns.

 

The SN74LS33DR is available in a 14-SOIC surface-mount package. It operates within an ambient temperature range of 0°C to 70°C. The open-collector output feature is a key characteristic for specific circuit designs.

 

This logic gate is part of the LS (Low-power Schottky) technology family, offering a balance of speed and power consumption for various digital applications.
