Product Description

The SN74LS640N is an octal Bi-directional Bus Transceiver designed for asynchronous two-way communication between data buses. The device transmits data from the A bus to the B bus or from the B bus to the A bus depending upon the level at the direction control (DIR) input. The enable input (G) can be used to disable the device so the buses are effectively isolated. The -1 version of the SN74LS640 is identical to the standard versions except that the recommended maximum IOL is increased to 48mA. It is characterized for operation from 0 to 70°C.
Hysteresis at bus inputs improves noise margins
