说明

This 32-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 1.4 V to 3.6 V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.4 V to 3.6 V. This allows for universal low-voltage bidirectional translation between any of the 1.5-V, 1.8-V, 2.5-V, and 3.3-V voltage nodes.

The SN74AVCBH324245 is designed for asynchronous communication between data buses. The device transmits data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE)\ input can be used to disable the outputs, so the buses are effectively isolated.

特性
Member of the Texas Instruments Widebus+™ Family
DOC™ Circuitry Dynamically Changes Output Impedance, Resulting in Noise Reduction Without Speed Degradation
Dynamic Drive Capability Is Equivalent to Standard Outputs With IOH and IOL of
±24 mA at 3-V VCC
±15 mA at 2.3-V VCC
±9 mA at 1.65-V VCC
±6 mA at 1.4-V VCC
Control Inputs VIH/VIL Levels Are Referenced to VCCB Voltage
If Either VCC Input Is at GND, Both Ports Are in the High-Impedance State
Inputs/Outputs Can Tolerate Up To 4.6 V, Which Allows Mixed-Voltage-Mode Data Communications
Ioff Supports Partial-Power-Down Mode Operation
Fully Configurable Dual-Rail Design Allows Each Port to Operate Over Full 1.4-V to 3.6-V Power-Supply Range
Bus Hold on Data Inputs Eliminates the Need for External Pullup/Pulldown Resistors
Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II
ESD Protection Exceeds JESD 22
