Details
By tracking the V CCA and V CCB voltages on the A and B ports respectively, the SN74LVC8T245 ensures seamless data transmission from one bus to another based on the direction-control (DIR) and output-enable (OE) inputs. When the B-port outputs are activated, data is transmitted from the A bus to the B bus, and vice versa when the A-port outputs are activated. This intelligent functionality helps prevent excess current flow and ensures efficient operation
Key Features
- Control inputs V IH/V IL levels are referenced to V CCA voltage
- V CC isolation feature – if either V CC input is at GND, all are in the high-impedance state
- Fully configurable dual-rail design allows each port to operate over the full 1.65-V to 5.5-V power-supply range
- Latch-up performance exceeds 100 mA per JESD 78, class II
- ESD protection exceeds JESD 22
- 4000-V Human-Body Model (A114-A)
- 100-V Machine Model (A115-A)
- 1000-V Charged-Device Model (C101)
