The ADCMP563/ADCMP564 are dual, high speed ECL comparators with a propagation delay of 700 ps and a propagation delay dispersion of 75 ps.
The ADCMP563 and ADCMP564 are dual, high‑speed ECL comparators fabricated on Analog Devices’ XFCB process. They feature differential ECL‑compatible outputs, 700 ps typical propagation delay, and programmable hysteresis (ADCMP564). The devices operate over an industrial temperature range of –40 °C to +85 °C and are supplied with ±5 V rails.
The datasheet provides detailed electrical characteristics, absolute maximum ratings, pin configurations, typical performance graphs, and thermal considerations. It also includes application information for high‑speed instrumentation, test equipment, and line‑receiver circuits.
| Propagation delay (typical) | 700 ps |
|---|---|
| Propagation delay dispersion | ≤ 75 ps |
| Input common‑mode range | -2.0 V to +3.0 V |
| Supply voltage | +5.0 V / -5.2 V |
| Typical supply current (positive) | 3.2 mA |
| Operating temperature range | -40 °C to +85 °C |
The typical propagation delay is 700 ps with a dispersion of less than 75 ps.
They are specified for operation from –40 °C to +85 °C.
The devices use a positive supply of +5.0 V and a negative supply of –5.2 V.
