Disadvantages

  • Limited voltage range: The supply voltage range is restricted to 2.0V to 3.6V, which may not be compatible with all systems.
  • Sensitivity to noise: Being a high-speed device, it may be more susceptible to noise interference.

Working Principles

The 74LCX16373MEA is a transparent latch that stores and transfers data. When the latch enable (LE) signal is active, the data inputs (D0-D15) are latched onto the outputs (Q0-Q15). The output enable (OE) signal allows the outputs to be put into a high-impedance state, enabling multiple devices to share a common bus.

Detailed Application Field Plans

  • Data storage and transfer in microcontrollers and microprocessors
  • Memory interfacing in computer systems
  • Communication systems requiring high-speed data transfer
