SN74LVC1T45 Bus Transceiver

Texas Instruments' single-bit noninverting bus transceiver uses two separate configurable power-supply rails. The A port is designed to track V_CCA. V_CCA accepts any supply voltage from 1.65 V to 5.5 V. The B port is designed to track V_CCB. V_CCB accepts any supply voltage from 1.65 V to 5.5 V. This allows for universal low-voltage bidirectional translation between any of the 1.8 V, 2.5 V, 3.3 V, and 5 V voltage nodes.

Features

• Available in the NanoFree™ package
• Fully configurable dual-rail design allows each port to operate over the full 1.65 V to 5.5 V power-supply range
• V_CC isolation feature – if either V_CC input is at GND, both ports are in the high-impedance state
• DIR input circuit referenced to V_CCA
• Low power consumption, 4 µA max I_CC
• ±24 mA output drive at 3.3 V
• I_off supports partial-power-down mode operation
• Latch-up performance exceeds 100 mA Per JESD 78, class II
