Product Overview: SN74LVTH373PWR from Texas Instruments

The SN74LVTH373PWR is a high-performance, octal transparent D-type latch designed by Texas Instruments. This device is part of the LVTH family, which stands for Low-Voltage BiCMOS technology with true TTL input compatibility. As a transparent latch, it allows data to flow from the input to the output when the latch-enable (LE) input is high and latches data when LE is low.

The SN74LVTH373PWR operates at a nominal voltage of 3.3V, which makes it suitable for interfacing with 3.3V logic levels while still being 5V tolerant at the input, providing a great deal of flexibility in mixed-voltage systems. It also features a wide operating voltage range from 2.7V to 3.6V, allowing it to work reliably across various conditions.

This device comes in a TSSOP (Thin Shrink Small Outline Package) form factor, with the package designated by the PWR suffix. The TSSOP package is advantageous for space-constrained applications due to its reduced body size and thinner profile compared to standard SSOP packages. The SN74LVTH373PWR has 20 pins, providing eight bits of latching capability, which makes it ideal for bus-oriented applications.

The SN74LVTH373PWR features a high drive capability, with outputs capable of sinking up to 64 mA and sourcing up to 32 mA, providing excellent signal integrity. Additionally, the device boasts a fast propagation delay, ensuring quick response times for critical applications. The latch also has bus hold data inputs, which eliminate the need for external pull-up or pull-down resistors, simplifying PCB design and reducing component count.

Texas Instruments has designed this latch with performance and reliability in mind, ensuring it meets the stringent requirements for industrial and commercial use. It is widely used in data storage, communication systems, computers, and wherever stable and reliable latching of data is necessary.

Overall, the SN74LVTH373PWR by Texas Instruments is a robust, versatile, and reliable solution for designers looking to incorporate an 8-bit transparent latch into their digital logic systems, especially where low-voltage operation and high-speed performance are critical.
