ON Semiconductor 74HCT573ADTR2 Product Overview

The 74HCT573ADTR2 is a high-performance, octal transparent D-type latch designed and manufactured by ON Semiconductor. It is a part of the 74HCT series, which is compatible with low power Schottky TTL (LSTTL). This integrated circuit is widely used in digital applications where the flow of data needs to be controlled by a latch enable (LE) input. The device is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

The 74HCT573ADTR2 features eight latches with 3-state outputs for bus organized systems applications. The 3-state outputs can be set to either a high impedance state, a logical high, or a logical low, which allows for the outputs to be connected directly to a bus while preventing bus contention. When the latch enable (LE) input is high, the Q outputs will follow the data (D) inputs. When LE is low, the data that meets the setup time requirements is latched, and the Q outputs will remain stable regardless of changes to the input data.

This device is fabricated with ON Semiconductor's high-performance silicon-gate CMOS technology, which ensures low power consumption and a broad operating voltage range. The 74HCT573ADTR2 operates from a 4.5V to 5.5V supply, making it compatible with most 5V systems. It also provides TTL level input compatibility when operated at a VCC of 5V.

The 74HCT573ADTR2 is supplied in a TSSOP-20 package, which is designed for surface mounting, making it ideal for compact and high-density circuit designs. The product is also available in tape and reel packaging, facilitating automated assembly processes and mass production.

Key features of the 74HCT573ADTR2 include:

• Octal D-type transparent latches with 3-state outputs
• Wide operating voltage range of 4.5V to 5.5V
