Functional Description
These 18-bit universal bus transceivers can be operated in
transparent, latched or clock modes by combining D-type
latches and D-type flip-flops. Data flow in each direction is
controlled by output enable (OEAB and OEBA), latch enable
(LEAB and LEBA), and clock inputs (CLKAB and CLKBA). For
A-to-B data flow, the device operates in transparent mode
when LEAB is HIGH. When LEAB is LOW, the A data is
latched if CLKAB is held at a HIGH or LOW logic level. If LEAB
is LOW, the A bus data is stored in the latch/flip-flop on the
LOW-to-HIGH transition of CLKAB. OEAB performs the output
enable function on the B port. Data flow from B-to-A is similar
to that of A-to-B and is controlled by OEBA, LEBA, and
CLKBA. The output buffers are designed with a power-off
disable feature to allow live insertion of boards.
THE CY74FCT163501 has 24-mA balanced output drivers
with current limiting resistors in the outputs. This reduces the
need for external terminating resistors, as well as provides for
minimal undershoot and reduced ground bounce. The
CY74FCT163501 is ideal for driving transmission lines.
The CY74FCT163H501 is a 24-mA balanced output part, that
has “bus hold” on the data inputs. The device retains the
input’s last state whenever the input goes to high impedance.
This eliminates the need for pull-up/down resistors and
prevents floating inputs.

Output level before the indicated steady-state input conditions were established, provided that CLKAB was HIGH before LEAB went LOW.
Operation beyond the limits set forth may impair the useful life of the device. Unless otherwise noted, these limits are over the operating free-air temperature range.
Unused inputs must always be connected to an appropriate logic voltage level, preferably either VCC or ground.

Notes:
8. Typical values are at VCC=3.3V, TA = +25˚C ambient.
9. This parameter is specified but not tested.
10. Not more than one output should be shorted at a time. Duration of short should not exceed one second. The use of high-speed test apparatus and/or sample
and hold techniques are preferable in order to minimize internal chip heating and more accurately reflect operational values. Otherwise prolonged shorting of
a high output may raise the chip temperature well above normal and thereby cause invalid readings in other parametric tests. In any sequence of parameter
tests, IOS tests should be performed last.
11. Per TTL driven input (VIN=3.4V); all other inputs at VCC or GND.
