Note: 1. Applying stresses in excess of the absolute maximum ratings may permanently damage the device. The values specified here are stress ratings only, and do not refer to operation under conditions outside either these conditions or the operating conditions. Operating for extended periods at the absolute maximum ratings may adversely influence device reliability. Unless otherwise specified, pin voltages must not exceed VCC + 0.5 V.

Description

The 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 largecapacitance  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.
