ON Semiconductor MC74VHCT259ADTR2G: 8-Bit Addressable Latch

The ON Semiconductor MC74VHCT259ADTR2G is a high-performance, 8-bit addressable latch designed for use in a wide range of digital applications. This integrated circuit (IC) is part of ON Semiconductor's VHCT family, which is known for its high-speed CMOS technology that offers the inherent benefits of CMOS—low power consumption and high noise immunity—while providing speeds that are comparable to LSTTL (Low-Power Schottky Transistor-Transistor Logic).

The MC74VHCT259ADTR2G is characterized by its versatility, allowing users to control data inputs and outputs with great precision. It features a common data input (D), four address inputs (A0 to A3), an active-low enable input (G), and eight mutually exclusive outputs (Q0 to Q7). When the enable input is low, the selected output will follow the data input when addressed by the address inputs. If the enable input is high, all outputs will remain in their previous states, regardless of the data or address inputs.

This device operates with a wide supply voltage range from 4.5V to 5.5V, making it suitable for interfacing with 5V logic systems. Its low power consumption and high drive capability make it ideal for battery-powered devices, as well as for interfacing with bus-oriented systems. The MC74VHCT259ADTR2G is also TTL-compatible, allowing it to be used in mixed-technology environments without the need for level shifting.

The latch is provided in a TSSOP-16 package, which is designed for space-saving in PCB designs. The package is also lead-free and fully RoHS compliant, ensuring that it meets the latest environmental standards for electronic components.

With its high-speed performance, low power consumption, and robust design, the ON Semiconductor MC74VHCT259ADTR2G is an excellent choice for applications requiring an addressable latch, such as data routing, memory address decoding, and various control functions in digital systems.

Whether you're designing consumer electronics, communication devices, or complex computing systems, the MC74VHCT259ADTR2G provides the reliability and functionality necessary to meet the demands of modern digital applications.
