High-Speed CMOS Logic

Quad-Bus Transceiver with Three-State Outputs

November 1997 - Revised October 2003

Features

Description

• Typical Propagation Delay (A to B, B to A) of 7ns at

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.

• Wide Operating Temperature Range . . . -55 C to 125 C

• Balanced Propagation Delay and Transition Times

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.
