| DM74ALS245A Octal 3-STATE Bus Transceiver DM74ALS245A Octal 3-STATE Bus Transceiver This advanced low power Schottky device contains 8 pairs of 3-STATE logic elements configured as octal bus transceivers. These circuits are designed for use in memory, microprocessor systems and in asynchronous bidirectional data buses. Two way communication between buses is controlled by the DIR input. Data transmits either from the 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 enable input which causes outputs to enter the high impedance mode so that the buses are effectively isolated. s Advanced oxide-isolated, ion-implanted Schottky TTL process s Non-inverting logic output s Glitch free bus during power up and down s 3-STATE outputs independently controlled on A and B buses s Low output impedance to drive terminated transmission lines to s Switching response specified into pF s Specified to interface with CMOS at VOH = VCC − 2V s PNP inputs to reduce input loading s Switching specifications guaranteed over full tempera- ture and VCC range Ordering Code: Order Number Package Number Package Description DM74ALS245AWM M20B 20-Lead Small Outline Integrated Circuit SOIC , JEDEC MS-013, 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, Wide Devices also available in Tape and Reel.

The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. The “Recommended Operating Conditions” table will define the conditions for actual device operation.
