The EL2019 offers a new feature previously unavailable in a comparator before—a master/slave edge triggered flip-flop. The comparator output will only change output state after a positive going clock edge is applied. Thus the output cant feed back to the input and cause oscillation.

Features
• Comparator cannot oscillate
• Fast response—5ns data to clock setup, 20ns clock to output
• Wide input differential voltage range—24V on ±15V supplies
• Wide input common mode voltage range—±12V
• Precision input stage—VOS = 1.5mV
• Low input bias current—100nA
• Low input offset current—30nA
• ±4.5V to ±18V supplies
• Three-State TTL compatible output
• No supply current glitch during switching
• 103dB voltage gain (Low input uncertainty ≈ 30µV)
• 50% power reduction in shut-down mode
• Input and flip-flop remain active in shutdown mode

Applications
• Analog to digital converters
• ATE pin receiver
• Zero crossing detector
• Window detector
• “Go/no-go” detector
