ON Semiconductor MC74LCX573M Octal Latch

The MC74LCX573M is a high-performance, octal latch integrated circuit from ON Semiconductor, designed to operate at exceptionally high speeds with a low power consumption. This device is part of the LCX family, which is fabricated with an advanced CMOS technology to achieve superior switching performance with high noise immunity and low static power consumption.

The octal latch is equipped with eight latches with three-state outputs for bus organized system applications. The MC74LCX573M is designed for use as input/output port for bus oriented applications and is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working memory. The device is capable of interfacing with 5V systems, which enables it to be used in mixed voltage applications.

Key features of the MC74LCX573M include:

• 5V Tolerant Inputs - The device can handle input voltages up to 5V, making it compatible with older logic levels.
• High Impedance Outputs - Under power-off conditions, the outputs do not load the circuit.
• Support for Live Insertion and Withdrawal - It can be inserted or removed from a live backplane without affecting the system.
• Power Down High Impedance Inputs and Outputs - This feature supports the partial power-down mode operation, enhancing the power conservation.
• Support for Latch-Up Performance - The device meets the JEDEC standard for latch-up performance.
• ESD Performance - With HBM and Machine Model protection, the device is safeguarded against electrostatic discharge events.

The MC74LCX573M is packaged in a 20-lead SOIC (Small Outline Integrated Circuit) package, providing a compact footprint for space-constrained applications. Its operating temperature range is from -40°C to +85°C, ensuring reliable performance across a wide range of environmental conditions.

With its low power consumption, high speed, and robust tolerance for voltage variations, the MC74LCX573M from ON Semiconductor is an excellent choice for designers looking to improve their digital systems' performance while maintaining low power usage and high noise immunity.
