产品概览
The M74LCX16245DTR2G from onsemi is a 16-bit bidirectional bus transceiver with 3.3V operation and 5V-tolerant inputs. It provides two 8-bit transceivers with independent direction and output enable controls, ideal for buffering 16-bit data buses between 3.3V and 5V domains.
主要规格

工作原理
Two 8-bit transceiver sections each have direction (DIR) and output enable (OE) controls. When DIR=HIGH and OE=LOW, data flows from A to B; when DIR=LOW and OE=LOW, from B to A. OE=HIGH tri-states both ports. 5V-tolerant inputs allow reception of 5V logic while powered from 3.3V, enabling mixed-voltage bus bridging.
应用
- 16-bit data bus buffering
- 3.3V to 5V bus bridging
- Memory interface
- Processor I/O expansion
