ON Semiconductor 74LVC373ADTR2G Octal Transparent Latch

The 74LVC373ADTR2G from ON Semiconductor is a high-performance, octal transparent D-type latch designed for use in a wide range of applications, including those requiring high-speed data storage and retrieval. This device is part of the LVC (Low-Voltage CMOS) family, which is renowned for its low power consumption and high noise immunity, making it an ideal choice for battery-operated and portable devices.

Featuring eight latches with 3-state outputs, the 74LVC373ADTR2G provides a convenient way to interface with bus-oriented systems. Each latch is capable of storing a single bit of data, which can be accessed and controlled through the latch enable (LE) and output enable (OE) inputs. When the LE input is high, the data on the D inputs is transferred to the latch outputs. The OE input, when low, allows the stored data to be read from the latch outputs. If OE is high, the outputs are in a high-impedance state, effectively isolating the latches from the bus.

This device operates over a broad voltage range of 1.2V to 3.6V, which allows it to interface with both 3.3V and 1.8V logic levels, providing the flexibility needed for mixed-voltage systems. The 74LVC373ADTR2G also features a high drive capability, with outputs capable of sourcing or sinking up to 24mA at 3.3V, ensuring reliable operation even with heavy loads.

ON Semiconductor's 74LVC373ADTR2G comes in a TSSOP-20 package, which is surface-mountable and suitable for automated assembly processes. It is also available in tape and reel packaging, making it easy to handle for large-scale production. The device is specified for operation from -40°C to +125°C, ensuring reliable performance across a wide range of environmental conditions.

With its combination of low power consumption, high noise immunity, and versatile power supply compatibility, the 74LVC373ADTR2G is a robust solution for designers looking to implement latching functions in their digital systems while maintaining signal integrity and power efficiency.
