4-Bit Dual-Supply Bus Buffer Level Translator

NLSV4T3234 4−Bit Dual−Supply Bus Buffer Level Translator with 26 W Output Series Resistor The NLSV4T3234 is a 4−bit configurable dual−supply voltage level translator. The input (B−) and output (A−) ports are designed to track two different power supply rails, VCCB and VCCA respectively. Both supply rails are configurable from 0.9 V to 4.5 V, allowing high−to−low and low−to high voltage translation from the input (B−) to the output (A−) port. The NLSV4T3234 is a low power voltage translator that contains series output resistors, and overvoltage tolerant (OVT) input and output protection. The 26 W series resistor on the output drivers minimizes ringing on the logic transition edges. The OVT feature allows the NLSV4T3234 to translate input signals greater than the input power supply VCCB and protects the IC from damage if a signal is connected to an output pin that is greater than VCCA.
