MC74ACT640DW

MC74ACT640 Octal 3-State Inverting Transciever The MC74ACT640 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. www.onsemi.com Features • • • • SOIC−20W DW SUFFIX CASE 751D Bidirectional Data Path A and B Outputs Sink 24 mA/Source −24 mA TTL Compatible Inputs These are Pb−Free Devices 1 ORDERING INFORMATION VCC OE B0 B1 B2 B3 B4 B5 B6 B7 20 19 18 17 16 15 14 13 12 11 See detailed ordering and shipping information in the package dimensions section on page 5 of this data sheet.
