The 74LCX16373TTR from STMicroelectronics is a high-performance, low-voltage 16-bit transparent latch with 5V tolerant inputs and outputs. Designed to be used in 3.3V power supply systems, this integrated circuit is part of STMicroelectronics’ LCX family, which is renowned for its low power consumption and high-speed operation.

This device features 16 D-type latches with 3-state non-inverting outputs. The transparent latches allow data to flow directly from the input to the output when the latch-enable (LE) input is high. When LE is low, the data that was present at the inputs at the time the transition occurred is latched. The OE (Output Enable) input, when low, allows the outputs to actively reflect the latched data, while a high OE disables the outputs, placing them in a high-impedance state.

The 74LCX16373TTR operates at a voltage range of 2.0V to 3.6V, which allows for lower voltage operation and interfacing with 5V logic levels without the need for external components. This makes it ideal for mixed-voltage applications and for interfacing with microprocessors or microcontrollers that operate at different voltage levels.

Additional features of the 74LCX16373TTR include its bus-hold circuitry, which eliminates the need for external pull-up or pull-down resistors by maintaining the last valid state during a high-impedance condition. The device is also characterized for operation from -40°C to +85°C, making it suitable for industrial temperature ranges.

The 74LCX16373TTR comes in a TSSOP48 (Thin Shrink Small Outline Package) which is a space-saving and lightweight package. The product is supplied in tape and reel packaging, making it suitable for automated assembly processes. This latch is perfect for applications in telecommunications, computing, and where low power, high speed, and efficient interfacing are required.

With its robust design, advanced features, and compatibility with various operating conditions, the STMicroelectronics 74LCX16373TTR is an excellent choice for designers looking to enhance the performance and reliability of their digital systems.
