Product Description
Pericom Semiconductors PI74FCT series of logic circuits are
pro duced in the Companys advanced 0.6 micron CMOS technology,
achieving industry leading speed grades.
The PI74FCT16646T, PI74FCT162646T, and PI74FCT162H646
are 16-bit registered transceivers organized as two independent
8-bit bus transceivers designed with 3-state D-type flip-flops and
control circuitry arranged for multiplexed transmission of data
directly from the data bus or from the internal storage registers. Each
8-bit transceiver utilizes the enable control (xOE) and direction pins
(xDIR) to control the transceiver functions. The Select (xSAB and
xSBA) control pins are used to select either real-time or stored data
transfer. The circuitry used for select control will eliminate the
typical decoding glitch that occurs in a multiplexer during the
transition between real-time and stored data. A low input level
selects real-time data and a high selects stored data.
The PI74FCT16646T output buffers are designed with a Power-Off
disable allowing live insertion of boards when used as backplane
drivers.
The PI74FCT162646T has ±24mA balanced output drivers. It is
designed with current limiting resistors at its outputs to control the
output edge rate resulting in lower ground bounce and undershoot.
This eliminates the need for external terminating resistors for most
interface applications.
The PI74FCT162H646T has Bus Hold which retains the inputs
last state whenever the input goes to high-impedance preventing
floating inputs and eliminating the need for pull-up/down resistors.
