RadHard-by-Design GENERAL DESCRIPTION Aeroflex’s RHD5911 is a radiation hardened, single supply, quad clocked comparator in a 16-pin SOIC package. The RHD5911 design uses specific circuit topology and la yout methods to mitigate total ionizing dose effects and single event latchup. These charac teristics make the RHD5911 especially suited for the harsh environment encountered in Deep Space miss ions. It is guaranteed operational from -55°C to +125°C. Available screened in ac cordance with MIL-PRF-38534 Class K, the RHD5911 is ideal for demanding military and space applications. ORGANIZATION AND APPLICATION The RHD5911 quad clocked comparator is intended for operation with dynamic signals on either or both inputs. Comparison is ’clocked’, that is the circuit functions as a rege nerative clocked latch with a digital output. For slow input signals with small input differences the comparators can be expected to respond to small noise signals at the inputs. Fe edback hysteresis is the responsibility of the user to avoid ’chattering’ on system noise. The comparators will accept signals from (GND + 0.8V) to V CC. The max clocked frequency is 50MHz. The max clock-to-output delay is 10ns. CMOS device drives have a negative temperature co efficient and the devices are therefore inherently tolerant to momentary shorts, although on chip thermal shutdown is not provided. All inputs and outputs are diode protected. The devices will not latch with SEU events above 100 Mev-cm 2/mg. Total dose degradation is minimal to above 1Mrad(Si). Displacement damage environments to neutron fluence equivalents in the mid 10 14 neutrons per cm2 range are readily tolerated. There is no sensitivity to low-dose rate (ELDRS) effects. SEU effects are application dependant. The RHD5911 16-pin clocked comparator allow pairs of comparators to access and hold data until needed.
