SN74LVCH16T245 - Texas Instruments

SN74LVCH16T245 16-bit Dual-supply Bus Transceiver

This 16-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 1.65 V to 5.5 V. The B port is designed to track VCCB. VCCB 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.

Features

•1 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 and Outputs Allow Mixed-Voltage-Mode Data Communications
• Fully Configurable Dual-Rail Design Allows Each Port to Operate Over the Full 1.65 V to 5.5 V Power-Supply Range
• Bus Hold on Data Inputs Eliminates the Need for External Pullup and Pulldown Resistors
• Ioff Supports Partial-Power-Down Mode Operation
• Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II
• ESD Protection Exceeds JESD 22 2.
