SN74LS05DR Description

Short technical summary and product information.

The Texas Instruments SN74LS05DR is a versatile logic gate IC featuring six independent inverters. Each inverter has a single bipolar input and an open-collector output, requiring external pull-up resistors for proper operation. This configuration allows for active-low wired-OR or active-high wire-AND functions when multiple devices are connected.

 

With a supply voltage range of 4.75V to 5.25V, the SN74LS05DR is suitable for various digital logic applications. It offers a maximum propagation delay of 32ns at 5V with a 15pF load capacitance, indicating high-speed performance. The device operates within a temperature range of 0°C to 70°C and has an output current capability of 8mA.

 

The SN74LS05DR is supplied in a 14-SOIC surface mount package, measuring 14-SOIC (0.154", 3.90mm Width). Its open-collector outputs are useful for generating higher VOH levels and interfacing with different voltage domains. The inclusion of input clamp diodes enhances its robustness.

 

This component is part of the LS (Low-power Schottky) technology family, known for its balance of speed and power consumption. The SN74LS05DR is designed for general-purpose digital logic applications where inverting functions and open-collector outputs are required.
