产品概览
MC74LCX16373DTG from onsemi is a 16-bit transparent D-type latch with 3-state outputs. Two independent 8-bit sections. 2.7-3.6V supply with 5V tolerant I/O. 4.5ns propagation. TSSOP-48.
工作原理
When LE is high, data flows through transparently. When LE goes low, data is latched. OE controls 3-state output. Two 8-bit sections can be used independently.
