Description of SN74ALVCH373DGVR by Texas Instruments

The SN74ALVCH373DGVR is a high-performance, octal transparent D-type latch designed and manufactured by Texas Instruments (TI), a leader in semiconductor solutions. This advanced integrated circuit (IC) is part of the ALVCH family, which is known for its low-voltage operation and high-speed interface technology. The SN74ALVCH373DGVR is particularly suitable for applications that require the temporary storage of data and possess the capability to retain the data while the output is non-active.

Constructed with an advanced BiCMOS technology, the SN74ALVCH373DGVR operates at a nominal voltage of 2.5V to 3.6V, which makes it ideal for interfacing with 3.3V logic levels. This compatibility ensures that the device can be used in mixed-voltage systems without the need for level-shifting components, simplifying design and reducing overall system cost.

The device features eight D-type 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 set up at the D inputs. A clear (CLR) input is provided to directly clear the Q outputs to a low level when taken low. The outputs can also be placed in a high-impedance state by taking the output-enable (OE) input high, allowing the outputs to effectively disconnect from the bus or shared data lines, which is useful in bus-oriented systems.

Encased in a 20-pin thin shrink small-outline package (TSSOP), the SN74ALVCH373DGVR is designed to occupy minimal space on a printed circuit board (PCB), making it a perfect choice for compact and high-density applications. The device also offers robust support for hot-insertion, which allows it to be added or removed from a system without the need to power down the system, thereby enhancing serviceability and reducing downtime.

TI's SN74ALVCH373DGVR 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 use in industrial, telecommunications, computing, and consumer electronics, among other applications. The combination of high-speed data storage, low power consumption, and small form factor makes this latch an excellent choice for designers looking to optimize their digital systems.
