High Speed CMOS Logic Hex Buffer/Line Driver,
Three-State Non-Inverting and Inverting
Description
The Harris CD74HC365, CD74HCT365, CD74HC366, and
CD74HCT366 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.
The CD74HC365 and CD74HCT365 are non-inverting buffers,
whereas the CD74HC366 and CD74HCT366 are inverting
buffers. These devices have two three-state control inputs (OE1
and OE2) which are NORed together to control all six gates.
The CD74HCT365 and CD74HCT366 logic families are speed,
function and pin compatible with the standard 74LS logic family.
