The ’HC640 and ’HCT640 silicon-gate CMOS three-state bidirectional inverting and non-inverting buffers are intended for two-way asynchronous munication between data buses. They have high drive current outputs which enable high-speed operation when driving large bus capacitances. These circuits possess the low power...
