CD74HCT243 General Description
The CD74HCT242, 'HC243 and 'HCT243 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 CD74HCT242 is an inverting buffer; the 'HC243 and 'HCT243 are non-inverting buffers. The states of the output enables (OEB, OEA) determine both the direction of flow (A to B, B to A), and the three-state mode.
