Preliminary Specifications Subject to Change.

MVL408 Quad Channel High Speed Level Translator

CMOS Compatible Outputs
Built-in 4.8 mV Hysteresis
50 mW/Channel Typical
7 nsec Propagation Delay Typical
3.5 nsec Rise and Fall Time Typical

FAST LEVEL TRANSLATOR FOR DISCRIMINATORS, TDCs AND WIRE CHAMBER FRONT-ENDS

The MVL408 is a version of the LeCroy MVL407 (a high performance level translator with built in hysteresis), with a CMOS compatible output instead of differential ECL, and substantially reduced power requirements. Small quantity prototypes are available in a 28-pin CLCC package. Contact LeCroy for other packaging options.
