SEMICONDUCTOR TECHNICAL DATA

Transcription

1 SEICONDUCTOR TECHNICAL DATA Ω The is designed for asynchronous communication between data buses. The device tramits data from the A bus to the B bus or from the B bus to the A bus depending upon the logic level at the direction control (DIR) input. The output enable (OE) input disables the device so the buses are effectively isolated. Both A and B outputs can sink up to 12mA; 25Ω resistors are included in the lower output circuit to reduce overshoot and undershoot. 25Ω OCTAL BIDIRECTIONAL TRANSCEIVER WITH 3 STATE INPUTS AND OUTPUTS FAST SCHOTTKY TTL The is characterized for operation from 0 C to 70 C. 3 State Outputs Drive Bus Lines or Buffer emory Address Registers Package Optio Include Plastic SOIC (DW Suffix) and Plastic SSOP (SD Suffix) VCC CONNECTION DIAGRA (TOP VIEW) OE B0 B1 B2 B3 B B5 13 B6 12 B7 11 DW SUFFIX PLASTIC SOIC CASE 751D T/R A0 A1 A2 A3 A4 A A6 A7 GND SD SUFFIX* PLASTIC SSOP CASE 940C 03 *Thermal ounting Techniques are Recommended.
