Description

The ’HC243 and ’HCT243 silicon-gate CMOS three-state

bidirectional noninverting buffers are intended for two-way

asynchronous communication between data buses. They

have high-drive-current outputs that enable high-speed oper-

ation 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 states of the output-enable (OEB, OEA) inputs

determine both the direction of ﬂow (A to B, B to A), and the

three-state mode.
