MM74HCT244

  The MM74HCT240 and MM74HCT244 3-STATE buffers utilize advanced silicon-gate CMOS technology and are general purpose high speed inverting and non-inverting buffers. They possess high drive current outputs which enable high speed operation even when driving large   bus capacitances. These circuits achieve speeds comparable to low power Schottky devices, while retaining the low power consumption of CMOS. All three devices are TTL input compatible and have a fanout of 15 LS-TTL equiva-lent inputs.

  MM74HCT devices are intended to interface between TTL and NMOS components and standard CMOS devices. These parts are also plug-in replacements for LS-TTL devices and can be used to reduce power consumption in existing designs.

  The MM74HCT240 is an inverting buffer and the MM74HCT244 is a non-inverting buffer.Each device has two active low enables (1G and 2G), and each enable inde-pendently controls 4 buffers.

  All inputs are protected from damage due to static dis-charge by diodes to V_CC and Ground.
