SN74LVC373AQPWRQ1 - Texas Instruments Octal Transparent D-Type Latches

The SN74LVC373AQPWRQ1 from Texas Instruments is a high-performance, octal transparent D-type latch that is designed to meet the rigorous demands of automotive and industrial applications. This integrated circuit provides a convenient and efficient means of temporarily storing data and features a latch-enable (LE) input that controls the data transfer from the D inputs to the Q outputs.

Constructed with an advanced LVC (Low-Voltage CMOS) process, the SN74LVC373AQPWRQ1 operates at a nominal voltage of 3.3V, but it is also 5V tolerant on input pins, which allows for flexible interfacing with both 3.3V and 5V logic levels. This makes it suitable for mixed-voltage systems and ensures compatibility with a wide range of digital circuits.

The device comes in a TSSOP (Thin Shrink Small Outline Package) with a PowerPAD™, designated by the orderable part number suffix 'QPWRQ1'. This package type is optimized for thermal performance and space-saving on printed circuit boards, making it ideal for compact automotive and industrial electronic assemblies.

Key features of the SN74LVC373AQPWRQ1 include:

• 8-bit transparent D-type latches with 3-state outputs
• Operational voltage range from 2.7V to 3.6V
• Maximum output current of -24mA and +24mA
• Support for mixed-mode voltage operation on all ports
• IOFF and power-up 3-state support to protect against bus contention
• Latch-up performance exceeds 100mA per JESD 78, Class II
• ESD protection exceeds JESD 22

The SN74LVC373AQPWRQ1 is also characterized for operation from -40°C to 125°C, ensuring reliable performance across a broad range of temperature conditions. This temperature range, coupled with the device's robust latch-up and ESD protection features, makes it an excellent choice for automotive control units, industrial automation systems, and other mission-critical applications where data integrity and system reliability are paramount.

Overall, the SN74LVC373AQPWRQ1 is a testament to Texas Instruments' commitment to providing high-quality, reliable components for the automotive and industrial markets, and it stands as a versatile solution for designers looking to implement secure data latching functionality in their systems.
