NTE1414 Datasheet | NTE Electronics

Description : The NTE1414 is an LSI integrated circuit in a 40- Lead DIP type package designed for AC INPUT clock timers capable of randomly setting “ON hour” and “OFF hour” 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, “ON hour”, and “OFF hour” 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.
