Octal Three-State Bus Transceiver, Inverting Features Description Buffered Inputs The ’HC640 and ’HCT640 silicon-gate CMOS three-state
bidirectional inverting and non-inverting buffers are intended
for two-way asynchronous communication 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 dissipation of CMOS
circuits, and have speeds comparable to low power Schottky
TTL circuits. They can drive 15 LSTTL loads. The ’HC640
and ’HCT640 are inverting buffers. Three-State Outputs Applications in Multiple-Data-Bus Architecture Fanout (Over Temperature Range) …
