Product Overview: SN74LVC373A Octal Transparent D-Type Latches

The SN74LVC373A from Texas Instruments is a high-performance, octal transparent D-type latch that is designed to operate from a 2.7 V to 3.6 V power supply, making it ideal for interfacing with 3.3 V logic in a wide range of applications. This integrated circuit is part of the LVC family, which stands for Low-Voltage CMOS, indicating that it is optimized for low-power consumption and high-speed operation.

The device features eight latches with 3-state outputs. When the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the levels that were set up at the D inputs. A 3-state output enables the latches to be connected directly to a bus or other data lines, where multiple devices can share the same connection without interference, as long as only one device is enabled at a time.

The SN74LVC373A is characterized for operation from -40°C to 85°C, ensuring reliable performance across a wide range of environmental conditions. This makes it suitable for industrial, commercial, and telecommunications applications. The device also offers support for mixed-mode voltage operation, allowing it to interface with 5 V signals on a 3.3 V supply, providing a high degree of flexibility for system design.

Texas Instruments ensures that this latch is designed with a robust latch-up performance, exceeding 250 mA per JESD 17, which is a testament to its reliability and resilience in the face of unexpected conditions. Additionally, the SN74LVC373A has ESD protection exceeding JESD 22, ensuring the device is safeguarded against electrostatic discharge events during handling and operation.

In summary, the SN74LVC373A from Texas Instruments is a versatile and reliable component that provides a high-speed, low-power solution for data storage and retrieval in digital systems. Its wide operating temperature range, compatibility with mixed-voltage environments, and protective features make it an excellent choice for a variety of applications requiring octal transparent D-type latches.
