The SN74LS540N from Texas Instruments is an octal buffer and line driver designed for high-performance applications. This integrated circuit features 3-state outputs, making it suitable for driving bus lines or buffering memory address registers. It operates with a supply voltage ranging from 4.75V to 5.25V and is characterized for operation from 0°C to 70°C.
The device offers inverting data at its outputs. The three-state control gate is a 2-input NOR gate, ensuring all eight outputs enter a high-impedance state when either G1 or G2 is high. This design enhances printed circuit board layout with a data flow-thru pinout, placing all inputs on the opposite side from the outputs.
Packaged in a 20-pin Dual In-line Package (PDIP), the SN74LS540N is designed for through-hole mounting. Its features include P-N-P inputs that reduce DC loading and hysteresis at the inputs to improve noise margins. The part number SN74LS540N is identical to SN74LS540N.A.
