SN74LVC245ADB

The SN74LVC245ADB is designed for asynchronous communication between data buses. The device transmits data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable the device so the buses are effectively isolated.

Features of the SN74LVC245ADB are:(1)EPIC(enhanced-performance implanted CMOS) submicron process;(2)typical VOLP (output ground bounce) < 0.8V at Vcc=3.3V,TA=25;(3)typical VOHV (output VOH undershoot) > 2V at Vcc=3.3V,TA=25;(4)supports mixed-mode signal operation on all ports(5-V input/output voltage with 3.3-V VCC);(5)power off disables outputs,permitting live insertion;(6)ESD protection exceeds 2000 V per;(7)latch-up performance exceeds 250 mA per JESD 17;(8)package options include plastic.
