MSM5547 is a 12 hour cycle AM/PM clock for a static fluorescent character display tube. Time correction is in hour, minute and 30 minute adjustments. Hour and minute are corrected by a 2 Hz fast-forward function. MSM5547 also has a contrast adjustment function for the fluorescent character display tube, which can set four levels of contrast, including 100% duty. FEATURES • 12 hour clock (AM/PM) • Applied for static fluorescent character display tube • Wide power supply range: 4 to 16V • 4.
