dm74ls573n Description

Short technical summary and product information.

The DM74LS573N from Texas Instruments is a high-speed octal D-type latch featuring 3-STATE outputs. This component is designed for easy interface with microprocessors, serving effectively as an input or output port.

Key electrical characteristics include a maximum input voltage of 7V and a supply voltage range of 4.75V to 5.25V, with a nominal 5V. The operating temperature range is from 0°C to 70°C. It supports a HIGH level input voltage of 2V and a LOW level input voltage of 0.8V. Output voltage levels are typically 2.7V for HIGH and 0.5V for LOW.

The device offers input clamp diodes to limit high-speed termination effects and is fully TTL and CMOS compatible. It is available in both 20-lead PDIP and 20-lead SOIC packages, suitable for through-hole mounting.

This latch is functionally identical to the DM74LS373 but features different pinouts, making it a versatile component for various digital logic applications.
