| DM74ALS640A Inverting Octal Bus Transceiver DM74ALS640A Inverting Octal Bus Transceiver This inverting octal bus transceiver is designed for asynchronous two-way communication between data busses. This device transmits data from the A bus to the B bus or from the B bus to the A bus depending upon the level at the direction control DIR input. The enable input G can be used to disable the device so the busses are effectively isolated. s Advanced Oxide-isolated Ion-implanted Schottky TTL process s Switching performance is guaranteed over full temperature and VCC supply range s Switching performance specified at 50 pF s PNP input design reduces input loading Ordering Code: Order Number Package Number Package Description DM74ALS640AWM M20B 20-Lead Small Outline Integrated Circuit SOIC , JEDEC MS-013, Wide DM74ALS640AN N20A 20-Lead Plastic Dual-In-Line Package PDIP , JEDEC MS-001, Wide Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code. Connection Diagram Logic Diagram Function Table L = LOW Logic Level H = HIGH Logic Level X = Either LOW or HIGH Logic Level Control Inputs Operation B Data to A Bus A Data to B Bus Isolation 2000 Fairchild Semiconductor Corporation DS008640 DM74ALS640A Absolute Maximum Ratings Note 1 Supply Voltage Input Voltage Control Inputs I/O ports Operating Free Air Temperature Range Storage Temperature Range Typical N Package M Package 7V 5.5V 0°C to +70°C −65°C to +150°C 53.0°C/W 72.0°C/W Note 1 The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. 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.
