The UM2002 is a bidirectional voltage level translator operational from 1.0V to 3.6V (Vref(A)) and 1.8V to 5.5V (Vref(B)), which allows bidirectional voltage translations between 1.0V and 5V without the need for a direction pin in open-drain or push-pull applications. Bit widths ranging from 1-bit or 2-bit are offered for level translation application with transmission speeds < 33 MHz for an open-drain system with a 50 pF capacitance and a pull-up of 197Ω.
The translators provide excellent ESD protection to lower voltage devices, and at the same time protect less ESD-resistant devices.
- Provides Bidirectional Voltage Translation with No Direction Pin
- Less than 1.5ns Maximum Propagation Delay
- Allows Voltage Level Translation between:
-- 1.0V Vref(A) and 1.8V, 2.5V, 3.3V or 5V Vref(B)
-- 1.2V Vref(A) and 1.8V, 2.5V, 3.3V or 5V Vref(B)
-- 1.8V Vref(A) and 3.3V or 5V Vref(B)
-- 2.0V Vref(A) and 5V Vref(B)
-- 3.3V Vref(A) and 5V Vref(B)
- Low 3.5Ω ON-State Connection between Input and Output Ports Provides Less Signal Distortion
- 5V Tolerant I/O Ports to Support Mixed-Mode Signal Operation
- High-Impedance An and Bn Pins for EN=LOW
