The SN74LS640 is an octal bus transceiver manufactured by Texas Instruments. It is designed for asynchronous two-way communication between data buses, allowing data transmission from the A bus to the B bus or vice versa, controlled by the DIR input. The enable input (G) can disable the device, effectively isolating the buses.
This transceiver operates with TTL input and output types and supports 8 channels. It is characterized by high-speed operation with a typical propagation delay (tpd) between 10 and 50 nanoseconds. The device is rated for catalog applications and operates within a temperature range of 0°C to 70°C.
The SN74LS640 is available in various package types including SOIC (DW), PDIP (N), and SOP (NS), all supporting surface mount technology. The device offers a maximum output current (IOL) of 24 mA and a maximum output current (IOH) of -15 mA.
This component is suitable for applications requiring bidirectional data transfer between bus systems where high-speed logic is essential. Its design includes hysteresis at bus inputs to improve noise margins and offers a choice of true or inverting logic and 3-state or open-collector outputs.
