ON Semiconductor MC74LCX373DTR2G Octal Transparent Latch

The ON Semiconductor MC74LCX373DTR2G is a high-performance, octal transparent latch that comes in a TSSOP-20 package. This integrated circuit is part of the LCX family, designed to provide optimal performance in 3.3V LVTTL logic while maintaining 5V tolerant inputs. This feature ensures that the device is compatible with mixed-voltage systems, allowing for a seamless interface with both 3.3V and 5V logic signals.

With its robust design, the MC74LCX373DTR2G is capable of withstanding the rigors of industrial applications. The device offers a latch-up performance that exceeds 500mA on all inputs and outputs, providing a high level of protection against over-current conditions. Additionally, its ESD tolerance is specified at more than 2000V Human Body Model (HBM), ensuring resilience against electrostatic discharges during handling and operation.

One of the key features of this octal transparent latch is its support for live insertion and withdrawal (hot insertion) without glitching, making it ideal for systems that require maintenance or upgrades without powering down. The device also includes a bus-hold feature on all inputs, which eliminates the need for external pull-up or pull-down resistors. This simplifies the design and reduces the bill of materials for the end product.

The MC74LCX373DTR2G operates over a broad voltage range of 2.0V to 3.6V, with a typical voltage of 3.3V, and provides a guaranteed low output voltage (VOL) level for a high drive capability. The device's performance is characterized for operation from -40°C to +85°C, making it suitable for a wide range of environmental conditions.

With its combination of features, the ON Semiconductor MC74LCX373DTR2G is a versatile component for designers looking to create reliable, high-speed digital systems. Whether it's used in computing, telecommunication, or industrial applications, this octal transparent latch is engineered to meet the demands of modern electronic designs.
