Three-State, Non-Inverting
Features
Description
• This Circuit is Processed in Accordance to MIL-STD-
883 and is Fully Conformant Under the Provisions of
Paragraph 1.2.1.
The CD54ACT623F3A is an octal bus transceiver that uti-
lizes Harris Advanced CMOS Logic technology. It is a non-
inverting three-state bidirectional transceiver-buffer that
allows for two-way transmission from “A” bus to “B” bus or
“B” bus to “A” bus depending on the logic levels of the Output
Enable (OE , OE ) inputs.
• Exceeds 2kV ESD Protection MIL-STD-883, Method 3015
• Meets JEDEC Standard No. 20
