Product Number ( please refer to Application guide )
RX - 4574 SG
: Q414574Bxxxxx00
•
By causing the high accuracy 32.768kHz clock (C-MOS input) such as TG - 3530 SA input,
the construction of the system of the high performance timekeeper is possible.
( Level adjustment by the C/R etc. at the time of the joint is unnecessary )
•
Functions are compatible with RX - 4574 LC and RTC - 4574 series
( except 32 kHz oscillation function ).
•
Comply with EU RoHS directive
