Functional Description • Octal Bus Buffer 74HCT240D: INVERTED, 3-STATE OUTPUTS 74HCT244D: NON-INVERTED, 3-STATE OUTPUTS 2. General The 74HCT240D, and 74HCT244D are high speed CMOS OCTAL BUS BUFFERs fabricated with silicon gate C2MOS technology. They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. Their inputs are compatible with TTL, NMOS, and CMOS output voltage levels. The 74HCT240D is an inverting 3-state buffer having two active-low output enables. The 74HCT244D is non-inverting 3-state buffer the HCT244A has two active-low output enables. These devices are designed to be used with 3-state memory address drivers, etc.
