产品概述
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
– 4000-V Human-Body Model (A114-A)
– 100-V Machine Model (A115-A)
– 1000-V Charged-Device Model (C101)
Applications
• Personal Electronic
• Industrial
• Enterprise
• Telecom
