NTE1414
Integrated Circuit
Digital AC Clock Timer for VCR
Description:
The NTE1414 is an LSI integrated circuit in a 40鈥揕ead DIP type package designed for AC INPUT
clock timers capable of randomly setting 鈥淥N hour鈥?and 鈥淥FF hour鈥?by a unit of a minute. This device
can also work as a stopwatch timing up to 1 hour, 59 minutes and 59 seconds, and as a sleep timer
operating for not more than 1 hour and 59 minutes once it is set.
A current hour, 鈥淥N hour鈥? and 鈥淥FF hour鈥?can be set easily in one of the following three modes: FAST
mode, in which the data of figures of minutes are sent fast at 50Hz or 60Hz; SLOW mode, in which
they are sent slow at 2Hz; and REVERSE, mode in which they are sent reversely.
