The MAX213E’s receiver propagation delay is typically 0.5µs in normal operation. In shutdown mode, propagation delay increases to 4µs for both rising and falling transitions. The MAX213E’s receiver inputs have approximately 0.5V hysteresis, except in shutdown, when receivers R4 and R5 have no hysteresis.

Applications Information charge pumps, decouple VCC to ground with a capacitor the same size as (or larger than) the charge-pump capacitors (C1–C4). V+ and V- as Power Supplies Capacitor Selection The capacitor type used for C1–C4 is not critical for proper operation. The MAX202E, MAX206–MAX208E, MAX211E, and MAX213E require 0.
