TTLNonInverting Octal Bus Transceiver
with OpenCollector Outputs
Description:
The NTE74LS641 is an octal bus transceiver in a 20Lead DIP type package designed for asynchronous
twoway communication between data buses. This 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
pin (G) can be used to disable the device so the buses are effectively isolated.
Features:
D BiDirectional Bus Transceiver
D Hysteresis at Bus Inputs Improves Noise Margins
D NonInverting (True) Logic
D OpenCollector Outputs
