Quad-Bus Transceiver with Three-State Outputs
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.

C to 125

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.
