SN74LVTH245 Datasheet

3.3-V Abt Octal Bus Transceivers With 3-State Outputs


These devices are designed for asynchronous communication between data buses. They transmit 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 devices so the buses are effectively isolated.To ensure the high-impedance state during power up or power down, OEshould be tied to VCCthrough a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. SN74LVTH245 Features &bull; Support Mixed-Mode Signal Operation (5-V Input and Output Voltages With 3.3-V VCC)&bull; Typical VOLP(Output Ground Bounce) <0.8 V at VCC= 3.3 V, TA= 25&deg;C&bull; Support Unregulated Battery Operation Down to 2.7 V&bull; Ioff and Power-Up 3-State Support Hot Insertion&bull; Bus Hold on Data Inputs Eliminates the Need for External Pullup/Pulldown Resistors&bull; Latch-Up Performance Exceeds 500 mA Per JESD 17&bull; ESD Protection Exceeds JESD 22 - 2000-V Human-Body Model (A114-A) - 200-V Machine Model (A115-A)
