... Hookswitch Operation The HSW input is used to inform the SA589 of whether the telephone off hook. Logic '0' is recognised as on-hook. Logic '1' is recognised as off-hook. When the HSW input rises from '0' to '1' the off-hook state is recognised immediately and keypad inputs are accepted. However, when the HSW input falls from '1' to '0' the on-hook state is not recognised for 200 - 300ms ...

... All keypad positions are disabled whilst memory dialling is in progress. Timed Break & Earth Loop Recall The SA589 supports both TBR and ELR and offers a common operating protocol in both cases. After a recall (Flash) operation, the dialling mode selected via the SELECT pin will be restored. ...

... SA589 FAMILY Oscillator Circuit This requires an external 560kHz ceramic resonator connected between OSC IN and OSC OUT to provide a timing reference for all chip functions. No other components are required or should be used. The oscillator circuit is of the 'single pin' type. Internally, the OSC IN pin is connected to V ...
