Digital AC Clock Timer for VCR
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.
Features:
D Complete Two–Operation/24 Hour Timer
D Alternate Current of 50Hz/60Hz Entered
D AM/PM or 24 Hour Display
D Hours can be Set in FORWARD or REVERSE Mode
D Sleep Timer Operation for not more than 1 Hour, 59 Minutes once it is Set
D Stopwatch Timing up to 1 Hour, 59 Minutes, and 59 Seconds
D Capable of Directly Driving a Fluorescent Lamp Tube
D Power Failure Indicator
