DESCRIPTION

The HCF4047B is a monolithic integrated circuit

fabricated

in

Metal

Oxide

Semiconductor

technology available in DIP and SOP packages.

The HCF4047B consist of a gatable astable

multivibrator with logic techniques incorporated to

permit

positive

or

negative

edge-triggered

monostable multivibrator action with retriggering

and external counting options. Inputs include

+TRIGGER -TRIGGER, ASTABLE, ASTABLE,

RETRIGGER, and EXTERNAL RESET. Buffered

outputs are Q, Q and OSCILLATOR. In all modes

of operation, an external capacitor must be

connected between C-Timing and RC-Common

terminals, and an external resistor must be

connected

between

the

R-Timing

and

RC-Common terminals.

For operating modes see functional terminal

connections and application notes.
