2 Description

The ’HC367, ’HCT367, ’HC368, and CD74HCT368

silicon gate CMOS three-state buffers are general

purpose high-speed non-inverting and inverting

buffers. The ’HC367 and ’HCT367 are non-inverting

buffers, whereas the ’HC368 and CD74HCT368 are

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.
