Working Principles

The 74HCT573PW,112 operates as an octal D-type transparent latch with 3-state outputs. When the latch enable (LE) input is high, the data inputs (D0-D7) are transferred to the outputs (Q0-Q7). The latch remains transparent as long as the LE input is high, allowing continuous data transfer. When the LE input is low, the outputs are latched and hold the last transferred data.

The output enable (OE) input controls the 3-state outputs. When OE is high, the outputs are enabled and can drive external circuitry. When OE is low, the outputs are in a high-impedance state, effectively disconnecting them from the external circuitry.

Detailed Application Field Plans

The 74HCT573PW,112 finds applications in various digital systems where data storage and transfer are required. Some common application fields include:

  1. Microcontrollers and microprocessors
