74HC366N,652

Overview

The 74HC366N,652 is a hex inverting buffer and line driver featuring three-state outputs controlled by active-low OE1 and OE2 inputs. It operates within a supply voltage range of 2.0 V to 6.0 V for the HC variant and 4.5 V to 5.5 V for the HCT variant. The device provides high noise immunity and low power dissipation. Inputs include clamp diodes allowing interface to voltages exceeding VCC. Propagation delay at 4.5 V is typically 12 ns for HC and 13 ns for HCT.

Feature Summary

• Hex inverting buffer/line driver with three-state outputs
• Wide supply voltage range from 2.0 V to 6.0 V
• High noise immunity and CMOS low power dissipation
• Inputs include clamp diodes for overvoltage tolerance

Applications

• Bus-oriented architectures requiring signal inversion and isolation
• Clock buffering and distribution systems
