QUAD BUS TRANSCEIVER
The SN54/ 74LS242 and SN54 / 74LS243 are Quad Bus Transmitters / Re-
ceivers designed for 4-line asynchronous 2-way data communications
between data buses.
• Hysteresis at Inputs to Improve Noise Immunity
• 2-Way Asynchronous Data Bus Communication
• Input Clamp Diodes Limit High-Speed Termination Effects
