Логическая ИС SN74LS240N

Буфер / драйвер линии , инвертирующий, 3 состояния, 4.75В до 5.25В, DIP-20

The SN74LS240N is an Octal Buffer and Line Driver designed specifically to improve both the performance and density of three-state memory address drivers, clock drivers and bus-oriented receivers and transmitters. The designer has a choice of selected combinations of inverting and non-inverting outputs, symmetrical, active-low output-control (G) inputs and complementary output-control (G and G\) inputs. These devices feature high fan-out, improved fan-in and 400mV noise margin. The SN74LS device can be used to drive terminated lines down to 133R.

• TTL input and CMOS output
• PNP inputs reduce DC loading
• Hysteresis at inputs improves noise margins
