MSC1210
Clock For 1/2 Duty VFD
FEDL1210-03
This version: MMayS.C20102010
Previous version: Jan. 1998
GENERAL DESCRIPTION
The MSC1210 is a clock for use in 1/2 duty VFD applications, featuring 4.194304 MHz crystal
controlled oscillator time base, wide ranges of power supply, and 12-hour format. The clock
correction rages are minutes, hours, and a 30-min ADJ (30-minute adjustment). The two clock
correction modes are available; one is 1Push-1ADJ correction mode, the other is 2 Hz fast advance
correction mode.
The MSC1210 is also provided with a function of 4-degree-switchable VFD luminance adjustment.
FEATURES
• 12-hour format
• Wide ranges of power supply: 4 V to 18 V (Built-in constant-voltage circuit)
• Usable for 1/2 Duty VFD
• 4.194304 MHz (crystal oscillation)
• Luminance: Switchable among 4 degrees
• Package options:
32-pin plastic SSOP
(SSOP32-P-430-1.00-K) (Product name: MSC1210GS-K)
30-pin plastic shrink DIP (SDIP30-P-400-1.778) (Product name: MSC1210SS)
