SN74LVC2T45 Dual-Bit Dual-Supply Bus Transceiver

This dual-bit noninverting bus transceiver uses two separate configurable power-supply rails. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.65V to 5.5V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65V to 5.5V. This allows for universal low-voltage bidirectional translation between any of the 1..

Features

• Fully configurable dual-rail design allows each port to operate over the full 1.65-V to 5.5-V powersupply range
• VCC isolation feature
  – if either VCC input is at GND, both ports are in the high-impedance state
• DIR input circuit referenced to VCCA
• Low power consumption, 4-μA maximum ICC
• Available in the Texas Instruments NanoFree™ package
• ±24-mA output drive at 3.3 V
• Ioff supports Partial-Power-Down mode operation
• Maximum data rates:
  – 420 Mbps (3.3-V to 5-V translation)
  – 210 Mbps (translate to 3.3 V)
  – 140 Mbps (translate to 2.5 V)
  – 75 Mbps (translate to 1.8 V)
• Latch-up per.
