CD74HC366-Q1 - Automotive Catalog High Speed CMOS Logic Hex Buffers/Line Drivers with Inverting 3-State Outputs

The CD74HC365-Q1, CD74HC366-Q1, and CD74HCT365-Q1 silicon gate CMOS three state buffers are general purpose high-speed non-inverting and inverting buffers. They have high drive current outputs which enable high speed operation even when driving large bus capacitances. These circuits possess the low power dissipation of CMOS circuitry, yet have speeds comparable to low power Schottky TTL circuits. Both circuits are capable of driving up to 15 low power Schottky inputs.

The CD74HC365-Q1 and CD74HCT365-Q1 are non-inverting buffers, whereas the CD74HC366-Q1 is an inverting buffer. These devices have two three-state control inputs (OE1 and OE2) which are NORed together to control all six gates.

The ’HCT365-Q1 logic families are speed, function and pin compatible with the standard LS logic family.
