Category: Tag:
Spread the components

The 74LS245 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 at the direction control (DIR) input. The enable input (G) can be used to disable the device so that the buses are effectively isolated.


• Bi-Directional bus transceiver in a high-density 20-pin package

• 3-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 current) 24 mA

• IOH (source current) −15 mA
