نظرة عامة على المنتج
The MC74LCX573DTR2 from onsemi is an octal D-type transparent latch with 3.3V operation and 5V-tolerant inputs. It is designed for 3.3V to 5V bus interfacing in mixed-voltage systems, providing 8-bit data latching with output enable for bus-oriented applications.

مبدأ العمل
When latch enable (LE) is HIGH, Q outputs follow D inputs (transparent mode). When LE goes LOW, outputs hold the last data. Output enable (OE) tri-states all outputs for bus sharing. 5V-tolerant inputs allow the latch to receive 5V logic signals while operating from a 3.3V supply.
