Product Description
4-channel Auto-Bidirectional Multi-Voltage Level Translator
Product Features
Provides bidirectional voltage translation with no direction pin
Supports up to 100MHz up translation and greater than 100MHz down translation at ≤ 30pf cap load and up to 40MHz up/down translation at 50pf cap load
Allows voltage-level translation between :0.85V and 1.8V, 2.5V, 3.3V, or 5V,1.2V and 1.8V, 2.5V, 3.3V, or 5V,1.8V and 2.5V, 3.3V, or 5V,2.5V and 3.3V, or 5V,3.3V and 5V
Low standby current
5V tolerance I/O port to support TTL
Low Ron provides less signal distortion
High-impedance I/O pins for EN = Low
Flow-through pinout for easy PCB trace routing
Latch-up performance >200mA per JESD 17
-40°C to 125°C Operating temperature range
