Working Principles

CD74HCT40105EG4 operates as an 8-bit addressable latch with an output enable feature. The latch stores data based on the address inputs (A, B, C) and retains it until a new address is provided or the clear input (CLR) is activated. The output enable (OE) pin controls the availability of the latch's outputs (Q0-Q7). When OE is high, the outputs are enabled, allowing the stored data to be read. Conversely, when OE is low, the outputs are disabled.
