The SN74LS640N is an octal bus transceiver manufactured by Texas Instruments, designed for asynchronous two-way communication between data buses. This device features 8 channels and supports TTL input and output types. It operates with a supply voltage range of 4.75V to 5.25V and has an operating temperature range of 0°C to 70°C.
The transceiver is configured for inverting logic and provides 3-state outputs. The 'LS' designation indicates its place within the Low-power Schottky technology family, known for its balance of speed and power consumption. The SN74LS640N is supplied in a 20-PDIP (Plastic Dual In-line Package) with a through-hole mounting type, making it suitable for breadboarding and through-hole PCB assembly.
Key electrical characteristics include a maximum IOL of 24mA and a maximum IOH of -15mA. The device is designed for applications requiring bidirectional data transfer between buses, controlled by direction and enable inputs. Its robust design and standard packaging make it a reliable choice for various digital interface applications.
