74LVC8T245DBQRG4

可配置电压转换和3态输出的8位双电源总线收发器 8-BIT DUAL-SUPPLY BUS TRANSCEIVER WITH CONFIGURABLE VOLTAGE TRANSLATION AND 3-STATE OUTPUTS

Description

This 8-bit noninverting bus transceiver uses two separate configurable power-supply rails. The SN74LVC8T245 is optimized to operate with VCCA and VCCB set at 1.65 V to 5.5 V. 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 1.8-V, 2.5-V, 3.3-V, and 5.5-V voltage nodes

Features

• Control Inputs VIH/VIL Levels Are Referenced to VCCA Voltage

• VCC Isolation Feature – If Either VCC Input Is at GND, All Are in the High-Impedance State

• Fully Configurable Dual-Rail Design Allows Each Port to Operate Over the Full 1.65-V to 5.5-V Power-Supply Range

• Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II

• ESD Protection Exceeds JESD 22
