Octal 3-STATE Bus Transceivers
DM74AS245 Octal Bus Transceiver with 3-STATE Outputs October 1986 Revised February 2000 DM74AS245 Octal Bus Transceiver with 3-STATE Outputs General Description Features This advanced Schottky device contains 8 pairs of � Advanced oxide-isolated, ion-implanted Schottky 3-STATE logic elements configured as octal bus transceiv- TTL process ers. These circuits are designed for use in memory, micro- � Non-inverting logic output processor systems and in asynchronous bidirectional data � 3-STATE outputs independently controlled on buses. Two way communication between buses is con- A and B buses trolled by the (DIR) input. Data transmits either from the A � Low output impedance to drive terminated transmission bus to the B bus or from the B bus to the A bus. Both the lines to 133Ω driver and receiver outputs can be disabled via the (G) � Switching response specified into 500Ω/50 pF enable input which causes outputs to enter the high imped- ance mode so that the buses are effectively isolated. � Specified to interface with CMOS at V = V − 2V OH CC � PNP inputs reduce input loading � Switching specifications guaranteed over full temperature and V range CC Ordering Code: Order Number Package Number Package Description DM74AS245WM M20B 20-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.300 Wide DM74AS245SJ M20D 20-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide DM74AS245N N20A 20-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide Devices also available in Tape and Reel.
