TLF9503 June 1995 54F74F245 Octal Bidirectional Transceiver with TRI-STATE Outputs General 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 mA (20 mA Mil) at the A ports and 64 mA (48 mA Mil) at the B ports The TransmitReceive (TR) input determines the direction of data flow through the bidirectional transceiver Transmit (ac- tive 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 mA (20 mA Mil) Y B outputs sink 64 mA (48 mA Mil) Y Guaranteed 4000V minimum ESD protection Commercial Military Package Package Description Number 74F245PC N20A 20-Lead (0300 Wide) Molded Dual-In-Line 54F245DM (Note 2) J20A 20-Lead Ceramic Dual-In-Line 74F245SC (Note 1) M20B 20-Lead (0300 Wide) Molded Small Outline JEDEC 74F245SJ (Note 1) M20D 20-Lead (0300 Wide) Molded Small Outline EIAJ 74F245MSA (Note 1) MSA20 20-Lead Molded Shrink Small Outline EIAJ Type II 54F245FM (Note 2) W20A 20-Lead Cerpack 54F245LM (Note 2) E20A 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 TLF9503 – 3 IEEEIEC TLF9503 – 4 TRI-STATE is a registered trademark of National Semiconductor Corporation C1995 National Semiconductor Corporation RRD-B30M75Printed in U S A |
