3.3V CMOS
18-BIT REGISTERED
TRANSCEIVER
Integrated Device Technology, Inc.
FEATURES:
high-speed, low-power 18-bit registered bus transceivers
combine D-type latches and D-type flip-flops to allow data flow
in transparent, latched and clocked modes. Data flow in each
direction is controlled by output-enable (OEAB and OEBA),
latch enable (LEAB and LEBA) and clock (CLKAB and CLKBA)
inputs. 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 port
to A port is similiar but requires using OEBA, LEBA and
CLKBA. Flow-through organization of signal pins simplifies
layout. All inputs are designed with hysteresis for improved
noise margin.
The FCT163501/A/C have series current limiting resistors.
These offer low ground bounce, minimal undershoot, and
controlled output fall times-reducing the need for external
series terminating resistors.

TSSOP and 15.7 mil pitch TVSOP
• Extended commercial range of -40°C to +85°C

• CMOS power levels (0.4µW typ. static)
• Rail-to-Rail output swing for increased noise margin
• Low Ground Bounce (0.3V typ.)
• Inputs (except I/O) can be driven by 3.3V or 5V
components

2. Minimum limits are guaranteed but not tested on Propagation Delays.
3. Skew between any two outputs, of the same package, switching in the same direction. This parameter is guaranteed by design.
4. Propagation Delays and Enable/Disable times are with VCC = 3.3V ±0.3V, Normal Range. For VCC = 2.7V to 3.6V, Extended Range, all Propagation Delays
and Enable/Disable times should be degraded by 20%.
