X-REL Semiconductor (X-REL) is a division of EASii IC dedicated to the design, manufacture and marketing of high reliability semiconductor components (ICs) up to extreme temperatures of -60 ° C to +230 ° C.

Power Management

PWM Controllers---XTR30010 is a family of small footprint PWM controllers de-signed for extreme reliability and high temperature applications such as DC/DC converters and PWM control. Being able to operate from input voltages as high as 50V, XTR30010 PWM controllers can run at frequencies as high as 800kHz, allowing the use of small footprint and low-cost external passive components.

Edge-Triggered Flip-Flop

The XTR54170 is a family of positive-edge-triggered D-type flip-flops.

XTR54175 have four D-type flip-flops with individual data input D and both Q and Q̅ outputs. The common clock CK and master reset MR ̅̅̅̅ inputs trigs and resets all flip-flops simultaneously.

XTR541G74 have a single D-type flip-flop with data D and clock CK inputs, Q and Q̅ outputs, and set S̅ and reset R̅ inputs.
