Hot-selling and scarce M74HCT244B1 OCTAL BUS BUFFER WITH 3 STATE OUTPUTS DIP20 spot stock

Product Descriptions

The M54/74HCT240, HCT241 and HCT244 are high speed CMOS OCTAL BUS BUFFERs fabricated in silicon gate C2 MOS technology.

They have the same high speed performance of LSTTL combined with true CMOS low power consumption. The designer has a choise of select combination of inverting and non-inverting outputs, symmetrical G (active low output control) input, and complementary G and G inputs. Each control input governs four BUS BUFFERs.

This integrated circuit has input and output characteristics that are fully compatible with 54/74 LSTTL logic families. M54/74HCT devices are designed to directly interface HSC2 MOS systems with TTL and NMOS components.

They are also plug in replacements for LSTTL devices giving a reduction of power consumption. These devices are designed to be used with 3 state memory address drivers, etc.

All inputs are equipped with protection circuits against static discharge and transient excess voltage.
