Again, no logic errors occur with 2V or more clock noise. 54HCT/74HCT ICs have an input buffer specially designed to yield TTL input levels of 0.8 and 2V. Their noise-immunity characteristics are therefore substantially different from those of 54HC/74HC devices. Pin and function compatible with 74HC74 . General Description. The VHC74 is an advanced high speed CMOS Dual. D-Type Flip-Flop fabricated with silicon gate CMOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the. CMOS low power dissipation.
