ON Semiconductor MC74VHC373DTR2 Octal Transparent Latch

The MC74VHC373DTR2 is a high-performance, octal transparent latch integrated circuit from ON Semiconductor, designed for use in a wide array of electronic applications requiring the temporary storage of data. This device is part of the VHC family, which is known for its low power consumption and high noise immunity, making it ideal for interfacing with high-speed logic systems.

Constructed with advanced silicon-gate CMOS technology, the MC74VHC373DTR2 offers a robust latch function with eight latches in a single package. Each latch is D-type, meaning it captures the state of the input when the Latch Enable (LE) pin is high, and retains this state when LE is low. The data is presented at the outputs when the Output Enable (OE) pin is low, ensuring controlled data flow and management.

The device operates over a wide voltage range of 2.0V to 5.5V, which allows it to be used in systems that require a lower power supply, further contributing to its energy efficiency. This feature also makes the MC74VHC373DTR2 compatible with a variety of logic levels, ensuring easy integration into mixed-voltage systems.

Additional key features of the MC74VHC373DTR2 include:

• High speed: The device can handle data rates typically up to 5.5V.
• Low power dissipation: It has a significantly reduced power consumption compared to conventional CMOS devices, which is crucial for battery-powered and energy-saving applications.
• High noise immunity: The latch is designed to withstand voltage spikes and other noise, ensuring reliable performance in electrically noisy environments.
• Improved output drive capability: The outputs can drive up to 8 LSTTL loads, providing excellent signal propagation to downstream components.

The MC74VHC373DTR2 is provided in a TSSOP-20 package, which is surface-mountable and suitable for automated assembly processes. Its compact form factor allows for a high-density mounting, making it an excellent choice for space-constrained applications. Whether it's for use in data storage, communication systems, computers, or control systems, the MC74VHC373DTR2 by ON Semiconductor provides a reliable and efficient solution for temporary data holding requirements.
