FAST CMOS

18-BIT REGISTERED

TRANSCEIVER

Integrated Device Technology, Inc.

CMOS technology. These high-speed, low-power 18-bit reg-

istered bus transceivers combine D-type latches and D-type

flip-flopstoallowdataflowintransparent, latchedandclocked

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,

thedeviceoperatesintransparentmodewhenLEABisHIGH.

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

isstoredinthelatch/flip-flopontheLOW-to-HIGHtransitionof

CLKAB. OEAB is the output enable for the B port. Data flow

fromtheBporttotheAportissimilarbutrequiresusing OEBA,

LEBA and CLKBA. Flow-through organization of signal pins

simplifies layout. All inputs are designed with hysteresis for

improved noise margin.

FEATURES:

• Common features:

– 0.5 MICRON CMOS Technology

– High-speed, low-power CMOS replacement for

ABT functions

– Typical tSK(o) (Output Skew) < 250ps

– Low input and output leakage ≤ 1µA (max.)

– ESD > 2000V per MIL-STD-883, Method 3015;

> 200V using machine model (C = 200pF, R = 0)

– Packages include 25 mil pitch SSOP, 19.6 mil pitch

TSSOP, 15.7 mil pitch TVSOP and 25 mil pitch Cerpack

– Extended commercial range of -40°C to +85°C

• Features for FCT16501AT/CT/ET:

– High drive outputs (-32mA IOH, 64mA IOL)

– Power off disable outputs permit “live insertion”

– Typical VOLP (Output Ground Bounce) < 1.0V at

VCC = 5V, TA = 25°C

The FCT16501AT/CT/ET are ideally suited for driving

high-capacitance loads and low-impedance backplanes. The

output buffers are designed with power off disable capability

to allow "live insertion" of boards when used as backplane

drivers.

• Features for FCT162501AT/CT/ET:

– Balanced Output Drivers: ±24mA (commercial),

±16mA (military)

The FCT162501AT/CT/ET have balanced output drive

with current limiting resistors. This offers low ground bounce,

minimalundershoot,andcontrolledoutputfalltimes–reducing

the need for external series terminating resistors. The

FCT162501AT/CT/ET are plug-in replacements for the

FCT16501AT/CT/ET and ABT16501 for on-board bus inter-

face applications.

– Reduced system switching noise

– Typical VOLP (Output Ground Bounce) < 0.6V at

VCC = 5V,TA = 25°C

• Features for FCT162H501AT/CT/ET:

– Bus Hold retains last active bus state during 3-state

– Eliminates the need for external pull up resistors

The FCT162H501AT/CT/ET have "Bus Hold" which re-

tains the input's last state whenever the input goes to high

impedance. This prevents "floating" inputs and eliminates the

need for pull-up/down resistors.
