Datasheet Details

The DM74121 is a monostable multivibrator featuring both positive and negative edge triggering with plementary outputs.

An internal 2kΩ timing resistor is provided for design convenience minimizing ponent count and layout problems.

this device can be used with a single external capacitor.
