CMOS LSI
LC74FCT16425T, 74FCT162245T
Fast 16-Bit CMOS Bidirectional Transceiver
Overview
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 direction-
ality 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 (脳 DIR) controls the
data flow direction and the output enable pin (脳 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.
