ON Semiconductor MC74HCT573ADTR2 Octal Latch

The MC74HCT573ADTR2 is a high-performance, octal transparent latch designed by ON Semiconductor, a leader in the semiconductor industry. This integrated circuit is part of the HCT family, which means it is compatible with CMOS and TTL logic levels, offering versatile interfacing with different types of digital circuits.

With its 3-state outputs, the MC74HCT573ADTR2 can be used in bus-oriented systems where data flow is necessary. Each latch is capable of storing a single bit of information, and the octal configuration allows for 8 bits (or 1 byte) of data to be stored simultaneously. The transparent nature of the latch means that when the Latch Enable (LE) input is high, the outputs follow the inputs. When LE is taken low, the data that was present at the inputs at the time of the transition is retained at the outputs until the LE is enabled once again.

This device operates optimally within a supply voltage range of 4.5V to 5.5V, which is typical for 5V digital systems. The low power consumption and high noise immunity of CMOS combined with the speed and drive capabilities of TTL make the MC74HCT573ADTR2 a robust choice for implementing latching functions in your digital applications.

Key features of the MC74HCT573ADTR2 include:

• Output Drive Capability: 15 LSTTL Loads
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 4.5V to 5.5V
• Low Input Current: 1µA
• High Noise Immunity Characteristic of CMOS Devices
• In Compliance with the JEDEC Standard No. 7A Requirements
• Chip Complexity: 20 FETs or 5 Equivalent Gates
• ESD Performance: HBM > 2000V; Machine Model > 200V

The device is supplied in a TSSOP-20 package, which allows for a compact footprint on printed circuit boards (PCBs). This package type is suitable for surface-mount technology (SMT), which is beneficial for modern, high-density electronic designs. The MC74HCT573ADTR2 is also available in tape and reel packaging, making it ideal for automated assembly processes.

Whether you're designing data buses, temporary storage registers, or need a reliable component for your digital logic circuits, the ON Semiconductor MC74HCT573ADTR2 offers the performance and quality required for your electronic projects.
