74S240 Octal Buffer and Line Driver IC With 3-State Output

The 74S240 designed as a 8-bit octal buffers and line drivers based  3-STATE buffer that utilizes advanced silicon-gate CMOS technology. The 74S240 improves the performance and density of three-state memory address drivers, clock drivers, and bus-oriented transmitters and receivers.

It features high drive current outputs that enable high speed operation even while driving large bus capacitances. Thereby circuits achieve speeds comparable to low power Schottky devices, while retaining the advantage of CMOS circuitry, i.e., high noise immunity and low power consumption. The designer come with a wide choice of selected combinations of inverting and noninverting outputs, symmetrical, active-low output control (G) inputs, and complementary output-control (G and G) inputs. High fan-out, enhanced fan-in, and a 400-mV noise margin are all features of these devices.

To drive terminated lines down to 133 MHz, the 74S240 Octal Buffer and Line Driver IC was employed. Two 4-bit buffers and drivers with independent output-enable (G) inputs make up this device. The gadget transfers data from the A inputs to the Y outputs when G is low. The outputs are in a high impedance state when G is high. Inputs are powered by either 3.3-V or 5-V devices in the 74S240. This functionality allows you to use this device as a translator in a system with both 3.3 and 5 volts.
