LC74FCT16245T and LC74FCT162245T 16-bit transceivers are fabricated in an advanced two-metal-layer CMOS technology. These fast, low-power transceivers are optimal for synchronous communication between two buses, referred to as the A and B busses. The directionality and output enable control in these products is designed to allow them to be used as either two independent 8-bit transceivers or as a single 16-bit transceiver. The direction control pin (× DIR) controls the data flow direction and the output enable pin (× OE) disables directionality control and disables both ports. The LC74FCT16245T is optimal for driving large-capacitance loads and low-impedance loads. The LC74FCT162245T provides a balanced output drive function that incorporates current limiting resistors. These minimize ground bounce and undershoot, and limit the output fall time. As a result, external series terminating resistors are no longer required. The LC74FCT162245T is a plug-in replacement for the LC74FCT16245T in on-board interface applications.
This document provides technical specifications for the Sanyo LC74FCT16425T and 74FCT162245T, which are 16-bit CMOS bidirectional transceivers designed for synchronous communication between two buses. These devices utilize advanced two-metal-layer CMOS technology to offer fast, low-power performance suitable for various interface applications.
