Product Description

The 74HCT573DBR is a latch that captures the data present on its input pins when the latch-enable (LE) input is high. The data is retained and presented at the output when the LE is taken low. The outputs can be placed in a high-impedance state by bringing the output enable (OE) input high, which is essential for interfacing with bus-oriented systems.

This device is fabricated with silicon gate CMOS technology which provides the inherent benefits of CMOS—low quiescent power and reduced noise susceptibility. The 74HCT573DBR is characterized for operation from -40°C to +85°C, ensuring reliability over a wide temperature range, making it suitable for various industrial applications.

With its SSOP packaging, the 74HCT573DBR is optimized for reduced space on PCBs, making it ideal for compact designs. Its compatibility with TTL levels makes it easy to interface with older logic families, providing flexibility in mixed-technology environments.

In summary, the 74HCT573DBR from Texas Instruments is a versatile and reliable component for digital systems requiring high-quality, transparent latches. Its performance and features make it a preferred choice for designers and engineers looking for a dependable solution in their digital applications.
