Pin No.

Pin Name

Description

1

C

Used to connect external capacitor

2

R

Used to connect external resistor

3

RCC

Common pin for connecting resistor and capacitor to it

4

AST’(Astable bar)

Low when used in Astable mode

5

AST

High when used in Astable mode

6

-Trigger

When used in Monostable mode we give High to Low transition to this pin

7

Vss

Ground pin of IC

8

+Trigger

When used in Monostable mode we give Low to High transition to this pin

9

EXT RESET

It’s an external reset pin. By giving a high pulse to this pin, it resets the output Q to low and Q’ to high

10

Q

Give normal high output

11

Q’

Inverse output of pin 10, means it gives low output

12

Retrigger

Used in Monostable mode to simultaneously retrigger +trigger and –trigger pin

13

OSC Out

Gives oscillated output

14

Vdd

Positive input pin of IC
