NOTE: When ordering, use the entire part number. The sufﬁx 96
denotes tape and reel. The sufﬁx T denotes a smallquantity reel of
250.
The ’HC367, ’HCT367, ’HC368, and CD74HCT368 silicon gate
CMOS threestate buffers are general purpose highspeed
noninverting and inverting buffers. They have high drive cur
rent 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 compara
ble to low power Schottky TTL circuits. Both circuits are capable
of driving up to 15 low power Schottky inputs.
The ’HC367 and ’HCT367 are noninverting buffers, whereas
the ’HC368 and CD74HCT368 are inverting buffers. These
devices have two output enables, one enable (OE1) controls 4
gates and the other (OE2) controls the remaining 2 gates.
The ’HCT367 and CD74HCT368 logic families are speed, func
tion and pin compatible with the standard LS logic family.
CAUTION: These devices are sensitive to electrostatic discharge. Users should follow proper IC Handling Procedures.
