ON Semiconductor NLV74HCT573ADWRG Octal Transparent Latch

The NLV74HCT573ADWRG from ON Semiconductor is a high-performance, octal transparent latch with three-state outputs designed for 2V to 6V VCC operation. This integrated circuit is part of the high-speed CMOS technology range and is compatible with LSTTL. It is particularly well-suited for driving bus lines or buffer memory address registers in your digital applications.

Featuring a robust design, the NLV74HCT573ADWRG consists of eight latches with three-state outputs for bus organized system applications. The device has a 20-pin package and is provided in a wide-body SOIC-20 package that ensures optimal thermal performance and space-saving on the PCB.

The device operates with an octal D-type transparent latch structure, meaning that when the latch enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is low, the latches hold the information that was present on the D inputs a setup time preceding the high-to-low transition of LE. The output enable (OE) input, when low, puts the eight outputs in a normal state, and when high, the outputs are in a high-impedance state, allowing for bus line control in a shared bus configuration.

Key features of the NLV74HCT573ADWRG include:

• High-speed CMOS technology
• Octal transparent latch with 3-state outputs
• Wide operating voltage range of 2V to 6V
• Low power consumption with a typical tPD of 15 ns at VCC = 5V
• Output drive capability of 15 LSTTL loads
• Low input current of 1µA maximum
• Bus line driving capability
• Wide-body SOIC-20 package for optimal PCB space utilization

With its versatile power supply range and low power consumption, the NLV74HCT573ADWRG is ideal for interfacing with different logic levels, supporting the creation of highly efficient and reliable systems. Its robust latch function ensures data integrity, and the three-state outputs facilitate bus connectivity, making it a great choice for complex digital systems requiring high-speed data control and bus management.
