Overview
The T74L2T45 is designed for asynchronous communication between two data buses. The logic level of the direction control (DIR) input activates either Port B or Port A output. When Port B output is activated, the device transmits data from Bus A to Bus B, and when Port A output is activated, it transmits data from Bus B to Bus A. The input circuits on Port A and Port B are always active and must be driven to a logic high or low level to prevent excessive ICC and ICCZ.
Port A is designed to track VCCA, which can accept any supply voltage from 1.65 V to 5.5 V. Port B is designed to track VCCB, which can also accept any supply voltage from 1.65 V to 5.5 V. This enables universal low-voltage bidirectional translation between 1.8 V, 2.5 V, 3.3 V, and 5 V voltage nodes.
The VCC isolation feature ensures that when either VCC input is grounded, both ports enter a high-impedance state.
The T74L2T45 is available in the VSSOP8 package and is characterized from −40°C to +125°C.
