Description
CIC RS0102/4 Breakout – 2/4 Bit Bidirectional Voltage-Level Translator
Overview
This 4-bit non-inverting translator is a bidirectional voltagelevel translator and can be used to establish digital switching compatibility between mixed-voltage systems. It uses two separate configurable power-supply rails, with the A ports supporting operating voltages from 1.65V to 5.5V while it tracks the VCCA supply, and the B ports supporting operating voltages from 2.3V to 5.5V while it tracks the VCCB supply. This allows the support of both lower and higher logic signal levels while providing bidirectional translation capabilities between any of the 1.8V, 2.5V, 3.3V and 5V voltage nodes.
Features
- No Direction-Control
- Data Rates
- 24Mbps (Push-Pull)
- 2Mbps (Open-Drain)
- 1.65V to 5.5V on A ports and 2.3V to 5.5V on B Ports (VCCA≤VCCB)
- VCC Isolation: If Either VCC is at GND, Both Ports are in the High-Impedance State
- No Power-Supply Sequencing Required: Either VCCA or VCCB can be Ramped First
- IOFF: Supports Partial-Power-Down Mode
- Extended Temperature: -40°C to +85°C
