PRECISION SINGLE CELL TIMER

ISSUE 2 - MAY 1998

DEVICE DESCRIPTION

These devices are precision timing circuits for

generation of accurate time delays or

oscillation. Advanced circuit design means that

these devices can operate from a single battery

cell with the minimum of quiescent current.

In monostable mode time delays are

controlled by a single resistor and capacitor

network. In astable mode the frequency and

du t y cy c l e c a n be a c c u r a t e l y an d

independently controlled with two external

resistors and one capacitor.

The threshold and trigger levels are normally

set as a proportion of V

by internal resistors.

These levels can be programmed by the use

of the control input pin.

When the trigger input reduces to a value

below the trigger level, the flip-flop is set and

the output goes high. With the trigger input

above the trigger level and the threshold input

above the threshold level, the flip-flop is reset

ZSCT1555

and the output goes low. The reset pin has

priority over all the other inputs and is used

to start new timing cycles. A low on the reset

input causes the flip-flop to reset forcing the

output low. Whenever the output is forced

low then the internal discharge transistor is

turned on.

FEATURES

•

0.9V supply operating voltage guaranteed
