DescriptionThe RC7341/42 is a very high speed dual comparator with latched input option and ECL compatible outputs capable of driving 509 terminated lines. The RC7341 is configured as a windows comparator whereas the RC7342 is configured as two independent comparators and is pin for pin compatible with the industry standard 9687 comparators. The RC7341/ 42's low propagation delay (2.0 ns maximum), wide input common range (-4V to +8V) and Iow bias current (+-10uA maximum) makes it ideal to for monitoring outputs from 1TL, CMOS, ECL and even GaAs devices in ATE applications. The propagation delay dispersion only it 100 ps (typical). The RC7341/42 features a high impedance input mode (ID) effectively removing the DO electrical bad other comparator inputs. The RC734/42 also has a latch function to sample the input wave toms Latches A and Bare controlled by differential latch enable (LEA and LEB) ECL signals. The RC7341/42 is fabricated using Raytheon's high performance complementary bipolar process.
The features of RC7341/42 can be summarized as (1)12V max differential input voltage; (2)low promation delays: 2.0ns maximum; (3)low delay diepersion (±100 ps typical); (4)common mode rejection >= 60dB; (5)lnput disable mode (transparent user); (6)2 pF maximum input capacitance (RC7341); (7)latch function; (8)available with common threshold input VIA/B window comparator (RC7341) or two indepent comparator (RC7342); (9)RC7342 is pin for pin compatible with 9687 comparators; (10)available in 16-pin SOIC. 20-pin PLCC or 16-pin P-DIP.
The absolute maximum ratings of RC7341/42 are (1)positive power supply, Vcc: +12V; (2)negative power supply, VEE :-7V; (3)difterence between Vcc and VEE: 19V; (4)input voltage at VIA+, VIB+: VCC+0.7V; (5)input voltage at VlA-, VlB-: VEE -0.7V; (6)differential input voltage |VlA+ - VlA-, | VlB+ - VIB-|, 16V; (7)input voltage at LEA, LEB: VCC; (8)lnput voltage at, LEA, LEB: VEE; (9)operating temperature range: -40°C to +85°C; (10)storage temperature range:-65 °C to +125°C; (11)lead temperature range (solder 10 sec): 260°C.
