STMicroelectronics 74LVX16373TTR Low Voltage 16-Bit D-Type Latch

The 74LVX16373TTR from STMicroelectronics is a high-performance, low-voltage 16-bit D-type transparent latch with 3-state outputs. This integrated circuit is part of the LVX family, which operates at a nominal voltage of 3.3V, making it ideal for interfacing with 3.3V systems and for low-power applications. The device is designed to be used as a temporary storage for data, capturing the data present on its inputs when the latch-enable (LE) input is high, and retaining that data when LE is low.

The 74LVX16373TTR features two separate sections, each with eight latches and a common latch-enable (LE) control. The dual enable feature allows for greater flexibility in controlling the flow of data. The transparent nature of the latches means that while LE is high, the outputs will change state as the data on the inputs changes, providing real-time tracking.

With its 3-state outputs, the 74LVX16373TTR can be placed in a high-impedance state, effectively disconnecting the output from the rest of the circuit. This is particularly useful in bus-oriented systems where multiple outputs can share the same connection lines without interference, as only one device should actively drive the bus at any time.

The device is provided in a TSSOP48 package, which is a space-saving and lightweight option suitable for surface-mount technology (SMT). The 74LVX16373TTR also boasts a wide operating temperature range, making it suitable for industrial applications where temperature conditions can be harsh.

Key features of the 74LVX16373TTR include its low quiescent current, which is important for battery-operated devices, and its low noise operation, which is critical for maintaining signal integrity in sensitive applications. The device is also characterized for operation from -40°C to +85°C, ensuring reliability over a wide range of environmental conditions.

Overall, the 74LVX16373TTR is a versatile and reliable component for any design requiring high-speed, low-power, non-volatile storage of digital data. Its compatibility with LVCMOS technology makes it a suitable choice for modern digital systems.
