Description
• Buffered Inputs
The Harris CD74HC365, CD74HCT365, CD74HC366, and
CD74HCT366 silicon gate CMOS three-state buffers are
general purpose high-speed non-inverting and inverting

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

• Wide Operating Temperature Range . . . -55 C to 125 C The CD74HC365 and CD74HCT365 are non-inverting buffers,
whereas the CD74HC366 and CD74HCT366 are inverting
buffers. These devices have two three-state control inputs (OE1
and OE2) which are NORed together to control all six gates.
