54F245 Datasheet | National Semiconductor

Description The ’F245 contains eight non-inverting bidirectional buffers with TRI-STATE outputs and is intended for bus-oriented applications Current sinking capability is 24 m A (20 m A Mil) at the A ports and 64 m A (48 m A Mil) at the B ports The Transmit Receive (T R) input determines the direction of data flow through the bidirectional transceiver Transmit (active HIGH) enables data from A ports to B ports Receive (active LOW) enables data from B ports to A ports The Output Enable input when HIGH disables both A and B ports by placing them in a High Z condition Features Y Non-inverting buffers Y Bidirectional data path Y A outputs sink 24 m A (20 m A Mil) Y B outputs sink 64 m A (48 m A Mil) Y Guaranteed 4000V minimum ESD protection mercial 74F245PC 74F245SC (Note 1) 74F245SJ (Note 1) 74F245MSA (Note 1) Military 54F245DM (Note 2) 54F245FM (Note 2) 54F245LM (Note 2) Package Number N20A J20A M20B M20D MSA20 W20A E20A 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 Molded Shrink Small Outline EIAJ Type II 20-Lead Cerpack 20-Lead Ceramic Leadless Chip Carrier Type C Note 1 Devices also available in 13 reel Use suffix e SCX SJX and MSAX Note 2 Military grade device with environmental and burn-in processing Use suffix e DMQB FMQB and LMQB Logic Symbols IEEE IEC TL F 9503 - 3 TRI-STATE is a registered trademark of National Semiconductor Corporation C1995 National Semiconductor Corporation TL F 9503 TL F 9503 - 4 RRD-B30M75 Printed in U S A Obsolete Connection Diagrams Pin Assignment for DIP SOIC SSOP and Flatpak Pin Assignment for LCC TL F 9503- 1 Unit Loading Fan Out Pin Names OE TR A0 - A7 B0 - B7 Description Output Enable Input (Active LOW) Transmit Receive Input Side A Inputs or TRI-STATE Outputs Side B Inputs or TRI-STATE Outputs 54F 74F UL HIGH LOW 10 20 10 20 3 5 1 083 150 40(38 3) 3 5 1 083 600 106...
