STMicroelectronics M54HCT240

The M54/74HCT240, HCT241 and HCT244 are high speed CMOS OCTAL BUS BUFFERs fabricated in silicon gate C2MOS 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.

DESCRIPTION

Each control input governs four BUS BUFFERs. This integrated circuit has input and output PIN CONNECTION (top view) HCT240 HCT241 HCT244 characteristics that are fully compatible with 54/74 LSTTL logic families. M54/74HCT devices are designed to directly interface HSC2MOS 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.
