MC74ACT643 Datasheet | Motorola Semiconductor

.. MC74AC643 MC74ACT643 Octal Bidirectional Transceiver with 3ĆState Outputs The MC74AC643/74ACT643 octal bus transceiver is designed for asynchronous two-way munication between data buses. The device transmits data from bus A to bus B when T/R = HIGH, or from bus B to bus A when T/R = LOW. The enable input can be used to disable the device so the buses are effectively isolated. - Bidirectional Data Path - A and B Outputs Sink 24 mA/Source - 24 mA - ′ACT643 Has TTL patible Inputs N SUFFIX CASE 738-03 PLASTIC OCTAL BIDIRECTIONAL TRANSCEIVER WITH 3-STATE OUTPUTS VCC 20 OE 19 B0 18 B1 17 B2 16 B3 15 B4 14 B5 13 B6 12 B7 11 1 T/R 2 A0 3 A1 4 A2 5 A3 6...
