CD54ACT623F3A S E M I C O N D U C T O R Octal Bus Transceiver Three-State, Non-Inverting July 1998 Features Description * This Circuit is Processed in Accordance to MIL-STD883 and is Fully Conformant Under the Provisions of Paragraph 1.2.1. The CD54ACT623F3A is an octal bus transceiver that utilizes Harris Advanced CMOS Logic technology. It is a noninverting 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 (OEAB, OEBA) inputs. * Exceeds 2kV ESD Protection MIL-STD-883, Method 3015 * Meets JEDEC Standard No. 20 The dual Output Enable provision gives these devices the capability to store data by simultaneously enabling OEAB and OEBA. Each output reinforces its input under these conditions, and when all other data sources to the bus lines are at high-impedance, both sets of bus lines will remain in their last states. * SCR - Latch-Up-Resistant CMOS Process and Circuit Design * Speed of Bipolar FAST/A/S with Significantly Reduced Power Consumption * Functionally and Pin-Compatible with Industry 54 Bipolar Types in the FAST, AS and S Series Ordering Information * Balanced Propagation Delays * Military Operating Temperature Range - Ceramic (CERDIP) 54 Series: . . . . . . . . -55 to 125oC * 24mA Output Drive Current, Drives 75 Lines without Need for Terminations A1 A2 A3 A4 A5 A6 A7 3 17 4 16 5 15 6 14 7 13 8 12 9 11 -55 to 125 20 Ld CERDIP F20.3 Pinout Functional Diagram 18 CD54ACT623F3A PKG.
