Digital Principles and Logic Design

Appendix 3: Pin Configuration of 74 Series Integrated Circuits

This section presents the pinout configuration of some commonly used integrated circuits of 74 series for ready reference. These may be helpful for logic designers. Open collector ICs of TTL are marked with a (*). Similar to the open collector TTL devices, CMOS devices with open drain output configuration are also marked with a (*).
