Features
Description
• Buffered Inputs
The Harris CD74HC367, CD74HCT367, CD74HC368, and
CD74HCT368 silicon gate CMOS three-state buffers are gen-
eral 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 cir-
cuits 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.
• High Current Bus Driver Outputs
• Two Independent Three-State Enable Controls

• Wide Operating Temperature Range . . . -55 C to 125 C
• Balanced Propagation Delay and Transition Times
ers. These devices have two output enables, one enable (OE1)
controls 4 gates and the other (OE2) controls the remaining 2
gates.
• Significant Power Reduction Compared to LSTTL
Logic ICs
The CD74HCT367 and CD74HCT368 logic families are speed,
function and pin compatible with the standard 74LS logic family.
