E1 E8 Row Inputs (Pins 1, 2, 10, 11, 14, 15, 16, 17) Under idle conditions, these inputs are held high by internal pull

up resistors.

As soon as a key is pressed, a logical 0 on that particular line signals to the circuit that a key has been selected.

is its low power consumption (in the order of 10 µA in the idle state). For this reason, the battery is perpetually in circuit. It has in fact been found that a light discharge current is beneficial to battery life. In its active state, the transmitter efficiency is increased by the use of a low duty cycle which is less than 2.5% for the modulating pulse trains. While no key is pressed, the circuit is in its idle state and the reference oscillator is stopped. Also, the eight address input lines.
