74HC7240 OCTAL BUS BUFFER

The M54/74HC7240, HC7241 and HC7244 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 outp.
