NTE1562
Integrated Circuit
Programmable Search System
for Audio Cassette
Description:
The NTE1562 is a monolithic integrated circuit consisting of a program selector capable of automatic
item selection with memory for 3 programs. The detection section is provided with protection from
misoperation due to noise. Consideration has been given as well to prevention of misoperation when
power is applied. The memory section is provided with LED driving outputs, enabling a display of the
program selection status.
Features:
D Built−in Protective Circuit for Overcurrent
D Detection Operation can be Stopped by External Input
D Provided with a Resetting Function for the Power Supply Switching On
D Wide Range of the Working Power Supply Voltage (4.5V to 14V)
Applications:
D Tape Decks
D Radio Cassette Tape Recorders
D Music Centers
D Accompaniment Music Players
