74LCX16373TTR

The 74LCX16373TTR from STMicroelectronics is a low-voltage CMOS 16-bit D-Type latch with 3-state outputs. Fabricated using sub-micron technology, it is designed for low power and high-speed 3.3V applications and can interface with a 5V signal environment for both inputs and outputs.

This latch features 5V tolerant inputs and outputs, an operating voltage range of 2.0V to 3.6V, and a high-speed performance with a propagation delay of 5.4 ns (max) at VCC = 3V. It offers symmetrical output impedance with |IOH|=|IOL|=24mA (min) at VCC = 3V and guarantees PCI bus levels at 24mA. The device also includes power-down protection on inputs and outputs and balanced propagation delays.

Each of the two independent 8-bit latches is controlled by a latch enable input (nLE) and an output enable input (OE). When nLE is high, the outputs follow the data input. When nLE is low, the outputs are latched to the logic level of the D input data. When OE is low, the outputs are in a normal logic state; when OE is high, the outputs are in a high-impedance state.

The 74LCX16373TTR is supplied in a 48-TSSOP package and is suitable for surface mounting. It operates across a wide temperature range of -55°C to 125°C.
