SN74AVCH24T245 - Texas Instruments

SN74AVCH24T245 24-Bit Dual-Supply Bus Transceiver

This 24-bit noninverting bus transceiver uses two separate configurable power-supply rails. The SN74AVCH24T245 is optimized to operate with VCCA/VCCB set at 1.4 V to 3.6 V. It is operational with VCCA/VCCB as low as 1.2 V. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.2 V to 3.6 V. The B port is designed to track VCCB. VCCB acc.

Features

• Control Inputs VIH/VIL Levels Are Referenced to VCCA Voltage
• VCC Isolation Feature
  – If Either VCC Input Is at GND, All Outputs Are in the High-Impedance State
• Overvoltage-Tolerant Inputs/Outputs Allow MixedVoltage-Mode Data Communications
• Fully Configurable Dual-Rail Design Allows Each Port to Operate Over Full 1.2-V to 3.6-V PowerSupply Range
• Ioff Supports Partial-Power-Down Mode Operation
• I/Os Are 4.6-V Tolerant
• Bus Hold on Data Inputs, Eliminating the Need for External Pullups/Pulldowns
• Max Data Rates
  – 380 Mbps (1.8-V to 3.3-V Translation)
  – 200 Mbps (<1.8-V to 3.3-V Trans.
