SN74LS38NSR Description

Short technical summary and product information.

The SN74LS38NSR from Texas Instruments is a logic IC featuring four independent 2-input NAND buffer gates. These gates are designed with open-collector outputs, which require pull-up resistors for proper operation and can be used for active-low wired-OR or active-high wired-AND functions. The device operates within a voltage range of 4.75V to 5.25V and supports a maximum data rate of 35 Mbps.

 

Key electrical characteristics include a maximum propagation delay of 32ns at 5V and 45pF, and an output current capability of 24mA. The input logic level is specified at 2V. The operating temperature range for this component is from 0°C to 70°C.

 

Packaged in a 14-SOIC (0.209", 5.30mm Width) surface-mount configuration, the SN74LS38NSR is suitable for various digital logic applications where open-collector outputs are beneficial for generating high VOH levels or implementing specific logic configurations. Its LS (Low-power Schottky) technology family ensures a balance of speed and power consumption.

 

This component is part of the LS logic family, known for its speed and efficiency. The open-collector output feature makes it versatile for bus-driving applications or when interfacing with different logic levels, provided appropriate pull-up resistors are used.
