DM54LS245 Datasheet (National Semiconductor) - TRI-STATE Octal Bus Transceiver

DM54LS245 Description

These octal bus transceivers are designed for asynchronous two-way communication between data buses The control function implementation minimizes external timing requirements The device allows data transmission from the A bus to the B bus or from the B bus to the A bus depending upon the logic level

DM54LS245 Features

* Y Y Y Bi-Directional bus transceiver in a high-density 20-pin package TRI-STATE outputs drive bus lines directly PNP inputs reduce DC loading on bus lines Hysteresis at bus inputs improve noise margins Typical propagation delay times port-to-port 8 ns Typical enable disable times 17 ns IOL (sink
