Octal 3-STATE Bus Transceiver
DM74ALS245A Octal 3-STATE Bus Transceiver September 1986 Revised February 2000 DM74ALS245A Octal 3-STATE Bus Transceiver General Description Features This advanced low power Schottky device contains 8 pairs � Advanced oxide-isolated, ion-implanted Schottky TTL of 3-STATE logic elements configured as octal bus trans- process ceivers. These circuits are designed for use in memory, � Non-inverting logic output microprocessor systems and in asynchronous bidirectional � Glitch free bus during power up and down data buses. Two way communication between buses is � 3-STATE outputs independently controlled on A and B controlled by the (DIR) input. Data transmits either from the buses A bus to the B bus or from the B bus to the A bus. Both the driver and receiver outputs can be disabled via the (G) � Low output impedance to drive terminated transmission lines to 133Ω enable input which causes outputs to enter the high imped- ance mode so that the buses are effectively isolated. � Switching response specified into 500Ω/50 pF � Specified to interface with CMOS at V = V − 2V OH CC � PNP inputs to reduce input loading � Switching specifications guaranteed over full tempera- ture and V range CC Ordering Code: Order Number Package Number Package Description DM74ALS245AWM M20B 20-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.300 Wide DM74ALS245ASJ M20D 20-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide DM74ALS245AMSA MSA20 20-Lead Shrink Small Outline Package (SSOP), EIAJ TYPE II, 5.3mm Wide DM74ALS245AN N20A 20-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide Devices also available in Tape and Reel.
