  • Data inputs are latched to the outputs on the rising edge of the clock pulse
  • Outputs can be enabled or disabled using the output enable (OE) pin
  • Master reset (MR) pin allows resetting all latches to a known state
  • Suitable for bus-oriented applications where multiple devices share a common data bus

Advantages and Disadvantages

Advantages: - High-speed operation due to CMOS technology - Wide operating voltage range allows compatibility with various systems - Low power consumption for energy-efficient designs - 3-state outputs enable easy bus sharing among multiple devices

Disadvantages: - Limited number of latches in a single package - Not suitable for applications requiring higher latch count

Working Principles

The SN74HC373ADBRG4 operates by latching the input data onto the outputs when a clock pulse is received. The latched data remains stable until the next clock pulse. The output enable (OE) pin controls whether the outputs are active or in a high-impedance state. The master reset (MR) pin resets all latches to a known state when activated.
