The SN74LS640-1N is an octal bus transceiver manufactured by Texas Instruments, designed for asynchronous two-way communication between data buses. This component features 8 channels and operates with TTL input and 3-state output types, supporting a voltage range of 4.75V to 5.25V.
With a technology family of LS, it offers high-speed performance with typical propagation delays between 10-50ns. The operating temperature range is specified from 0°C to 70°C. The transceiver is available in a 20-PDIP package and supports through-hole mounting.
Key electrical characteristics include an IOL (max) of 24mA and an IOH (max) of -15mA. The device is designed for efficient data transfer, with the direction controlled by the DIR input and the device disabled using the G input to isolate buses. The SN74LS640-1N also offers hysteresis at its bus inputs, which improves noise margins.
