MC74AC623 Datasheet | Motorola Semiconductor

.. MC74AC623 MC74ACT623 Octal Bidirectional Transceiver with 3ĆState Outputs The MC74AC623/74ACT623 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 m A/Source - 24 m A - ′ACT623 Has TTL patible Inputs N SUFFIX CASE 738-03 PLASTIC OCTAL BIDIRECTIONAL TRANSCEIVER WITH 3-STATE OUTPUTS VCC 20 GBA 19 B0 18 B1 17 B2 16 B3 15 B4 14 B5 13 B6 12 B7 11 1 GAB 2 A0 3 A1 4 A2 5 A3 6 A4 7 A5 8 A6 9 A7 10 GND DW SUFFIX CASE 751D-04 PLASTIC PIN NAMES A0- A7 GAB GBA B0- B7 Side A Inputs or 3-State Outputs Enable B Outputs Enable A Outputs Side B Inputs or 3-State Outputs TRUTH TABLE GAB H H L L GBA H H L L Applied Inputs H L H L Valid Direction I/P→O/P A to B A to B B to A B to A Output H L H L H = HIGH Voltage Level L = LOW Voltage Level FACT DATA Data Sheet 4 U . 5-1 ..
