XTRM Series XTR54170 HIGH TEMPERATURE EDGE-TRIGGERED D FLIP-FLOP FAMILY FEATURES
DESCRIPTION
Wide operating supply voltage from 2.8V to 5.5V. Operational beyond the -60°C to +230°C temperature range. Up to ±8mA output drive. Schmitt-Trigger Inputs allow better switching noise immunity. Ruggedized SMT packages. Also available as bare die.
The XTR54170 is a family of positive-edge-triggered D-type flipflops. XTR54175 have four D-type flip-flops with individual data input D and both Q and outputs. The common clock CK and master inputs trigs and resets all flip-flops simultaneously. reset XTR541G74 have a single D-type flip-flop with data D and clock CK inputs, Q and outputs, and set and reset inputs. Parts from the XTR54170 family are available in ruggedized SMT and through-hole packages. Parts are also available as bare dies.
APPLICATIONS Reliability-critical, Automotive, Aeronautics & Aerospace, Down-hole.

During transient operation, these pins can reach values under 0V and above VDD. Extreme values are limited by internal clamping diodes to GND and to VDD. 2 Operation beyond the specified temperature range is achieved.
