SN74LS38DR Description

Short technical summary and product information.

The Texas Instruments SN74LS38DR is a component within the LS technology family, featuring four independent 2-input NAND buffer gates. Each gate has an open-collector output, which requires pull-up resistors for proper operation and can be used for active-low wired-OR or active-high wired-AND functions. This device is designed for a supply voltage range of 4.75V to 5.25V and operates at a maximum data rate of 35 Mbps, with a typical propagation delay of 32ns at 5V and 45pF.

 

The SN74LS38DR is suitable for surface mount applications and comes in a 14-SOIC package. It operates within an ambient temperature range of 0°C to 70°C. The open-collector outputs are useful for generating high VOH levels. This logic gate is part of the broader Logic Gates category and is specifically a NAND gate.

 

Key electrical characteristics include 2 inputs per channel, 4 circuits, and an output current of 24mA. The input logic level is rated at 2V. These characteristics make the SN74LS38DR a versatile component for various digital logic applications requiring NAND functionality with open-collector outputs.
