| MC74AC623 MC74ACT623 Octal Bidirectional Transceiver with 3 State Outputs The MC74AC623/74ACT623 octal bus transceiver is designed for asynchronous two-way communication 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 * ACT623 Has TTL Compatible 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/PO/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 5-1 MC74AC623 MC74ACT623 MAXIMUM RATINGS* Symbol VCC Vin Vout Iin Iout ICC Tstg Parameter DC Supply Voltage (Referenced to GND) DC Input Voltage (Referenced to GND) DC Output Voltage (Referenced to GND) DC Input Current, per Pin DC Output Sink/Source Current, per Pin DC VCC or GND Current per Output Pin Storage Temperature Value -0.5 to +7.0 -0.5 to VCC +0.5 -0.5 to VCC +0.5 20 50 50 -65 to +150 Unit V V V mA mA mA C * Maximum Ratings are those values beyond which damage to the device may occur.
