ON Semiconductor MC74LCX373DWR2G Octal Transparent Latch

The MC74LCX373DWR2G is a high-performance, octal transparent D-type latch designed by ON Semiconductor, a leader in energy-efficient innovations. This integrated circuit is part of the LCX family, which is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation.

This particular device features eight latches with three-state outputs for bus organized system applications. The latches appear transparent to data when Latch Enable (LE) is HIGH. When LE is LOW, the data that meets the setup time is latched. Data appears on the bus when the Output Enable (OE) is LOW. When OE is HIGH, the outputs are in a high impedance state, which means they neither load the bus nor drive it, allowing multiple devices to be connected to the bus without contention.

The MC74LCX373DWR2G is characterized for operation from -40°C to +85°C, making it suitable for a wide range of industrial applications. The device is provided in a wide body 20-lead SOIC package, which is a surface-mount package that conserves space on printed circuit boards and facilitates efficient automated assembly processes.

Key features of the MC74LCX373DWR2G include:

• 5V tolerant inputs and outputs
• 2.3V to 3.6V V_CC specifications provided
• High impedance glitch free bus loading during entire power up and power down cycle
• Non-busy outputs directly drive bus lines
• Power-off high impedance inputs and outputs
• Supports live insertion and withdrawal (Note: to prevent excess current, a 1K ohm resistor should be placed in series with the bus hold or bus pull-up/down resistors)
• Latch-up performance exceeds 500mA
• ESD performance: Human body model >2000V; Machine model >200V

The MC74LCX373DWR2G is ideal for applications that require high-speed data transfer and storage, such as computer servers, networking equipment, and telecommunications systems. Its robust latch-up performance and ESD protection make it a reliable choice for complex electronic systems.

ON Semiconductor's commitment to quality ensures that the MC74LCX373DWR2G provides the performance and durability necessary for the most demanding applications. This octal transparent latch exemplifies the company's dedication to providing advanced solutions for data management and signal integrity.
