ON Semiconductor MC74LCX373DWR2 Octal Transparent Latch
The ON Semiconductor MC74LCX373DWR2 is a high-performance, octal transparent latch designed for use in applications requiring high-speed and 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 immunity to Latch-Up. The MC74LCX373DWR2 is suitable for operating in a wide range of applications, including memory address latching, data storage, and multiplexing.
The device consists of eight latches with 3-state outputs for bus-oriented applications. The latches are transparent D-type latches, meaning that while the latch-enable (LE) input is high, the Q outputs will follow the data (D) inputs. When LE is taken low, the data that was present at the D-inputs at the time the transition occurred will be retained at the Q outputs until LE is returned high again.
The MC74LCX373DWR2 operates at a voltage range of 2.3V to 3.6V, making it compatible with 3.3V logic levels while maintaining 5V tolerant inputs. This feature allows for mixed-voltage system integration, making it highly versatile for various applications. Additionally, the device supports a high drive capability of ±24mA at the outputs, ensuring good signal integrity and driving capabilities.
The packaging of the MC74LCX373DWR2 is a 20-lead SOIC (wide body) package, which provides a compact footprint while still ensuring ease of handling and manufacturing. The device also features a power-down high impedance input and output, which helps in power conservation when the device is not in active use.
ON Semiconductor has designed the MC74LCX373DWR2 with an emphasis on reliability and performance. It features a typical propagation delay time of only 4.5ns, contributing to its high-speed operation. Additionally, the device is fully specified over the -40°C to +85°C temperature range, making it reliable for industrial applications. With its robust design and advanced features, the MC74LCX373DWR2 is an excellent choice for designers looking for a high-quality octal transparent latch.
