54F545 Datasheet | National Semiconductor

Description The ’F545 is an 8-bit TRI-STATE high-speed transceiver It provides bidirectional drive for bus-oriented microprocessor and digital munications systems Straight through bidirectional transceivers are featured with 24 m A (20 m A Mil) bus drive capability on the A ports and 64 m A (48 m A Mil) bus drive capability on the B ports One input Transmit Receive (T R) determines the direction of logic signals through the bidirectional transceiver Transmit enables data from A ports to B ports Receive enables data from B ports to A ports The Output Enable input disables both A and B ports by placing them in a TRI-STATE condition Features Higher drive than 8304 8-bit bidirectional data flow reduces system package count TRI-STATE inputs outputs for interfacing with bus-oriented systems 24 m A (20 m A Mil) and 64 m A (48 m A Mil) bus drive capability on A and B ports respectively Transmit Receive and Output Enable simplify control logic Guaranteed 4000V minimum ESD protection Pin for Pin patible with Intel 8286 mercial 74F545PC Military Package Number N20A Package Description 20-Lead (0 300 Wide) Molded Dual-In-Line 20-Lead Ceramic Dual-In-Line 20-Lead (0 300 Wide) Molded Small Outline JEDEC 20-Lead (0 300 Wide) Molded Small Outline EIAJ 20-Lead Cerpack 20-Lead Ceramic Leadless Chip Carrier Type C 54F545DM (Note 2) 74F545SC (Note 1) 74F545SJ (Note 1) 54F545FM (Note 2) 54F545LM (Note 2) Note 1 Devices also available in 13 J20A M20B M20D W20A E20A reel Use suffix e SCX and SJX Note 2 Military grade device with environmental and burn-in processing Use suffix e DMQB FMQB and LMQB Logic Symbols TL F 9556 - 3 IEEE IEC TL F 9556 - 5 TRI-STATE is a registered trademark of National Semiconductor Corporation C1995 National Semiconductor Corporation TL F 9556 RRD-B30M105 Printed in U S A Connection Diagrams Pin Assignment for DIP SOIC and Flatpak Pin Assignment for LCC TL F 9556 - 2 TL F 9556- 1 Truth Table Inputs OE L L H T R L H X Bus B Data to...
