Functional Description
The
CY74FCT16646T
transceivers are three-state, D-type registers, and control
circuitry arranged for multiplexed transmission of data directly
from the input bus or from the internal registers. Data on the A
or B bus will be clocked into the registers as the appropriate
clock pin goes to a HIGH logic level. Output Enable (OE) and
direction pins (DIR) are provided to control the transceiver
function. In the transceiver mode, data present at the high
impedance port may be stored in either the A or B register, or
in both. The select controls can multiplex stored and real-time
(transparent mode) data. The direction control determines
which bus will receive data when the Output Enable (OE) is
Active LOW. In the isolation mode (Output Enable (OE) HIGH),
A data may be stored in the B register and/or B data may be
= 5V,
CC
stored in the A register.
This device is fully specified for partial-power-down
applications using I
preventing damaging current backflow through the device
when it is powered down.
= 5V,
The
CY74FCT16646T
CC
high-capacitance loads and low-impedance backplanes.
The CY74FCT162646T has 24-mA balanced output drivers
with current limiting resistors in the outputs. This reduces the
need for external terminating resistors and provides for
minimal undershoot and reduced ground bounce. The
CY74FCT162646T is ideal for driving transmission lines.
