2 Description

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.
