ON Semiconductor MC74LCX573DWR2 Octal Latch

The ON Semiconductor MC74LCX573DWR2 is a high-performance, octal D-type transparent latch integrated circuit designed for use in applications requiring high speed and low power consumption. This device is part of the LCX family, which is fabricated using an advanced CMOS technology to achieve fast propagation delays, low quiescent currents, and robust noise immunity.

With a 3.3V power supply, the MC74LCX573DWR2 is optimized for 5V tolerant input and output capability, allowing for interfacing with 5V systems. This makes it an ideal choice for mixed-voltage applications and for bridging the gap between 5V and 3.3V logic systems. The latch is capable of directly driving 24mA, which provides a good level of drive capability while maintaining low power dissipation.

The MC74LCX573DWR2 features eight latches with three-state outputs. Each latch is transparent, meaning that when the latch enable (LE) input is high, the Q outputs will follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the levels set up at the D inputs. Additionally, the octal latch includes an output enable (OE) input, which, when high, places the outputs in a high impedance state. This is particularly useful for interfacing with bus-oriented systems where multiple devices may need to share the same data lines.

This device is supplied in a 20-lead SOIC package, ensuring a compact footprint suitable for space-constrained applications. The MC74LCX573DWR2 is characterized for operation from -40°C to +85°C, making it reliable across a wide range of environmental conditions. It is also compliant with JEDEC standard no. 7A requirements, ensuring compatibility with standard industrial manufacturing processes and operating conditions.

ON Semiconductor's commitment to quality and reliability is evident in the MC74LCX573DWR2, making it a go-to choice for designers looking for a dependable octal latch solution for their digital circuit designs. Whether used in computing, telecommunication, or industrial applications, this IC delivers the performance and durability required for modern electronic systems.
