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.
