Integrated Device Technology, Inc.

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 FCT16244T/AT/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

DESCRIPTION:

The16-BitBuffer/LineDriverisforbusinterfaceorsignalbuffering

applicationsrequiringhighspeedandlowpowerdissipation. These

devices have a flow through pin organization, and shrink packaging

to simplify board layout. All inputs are designed with hysteresis for

improvednoisemargin. Thethree-statecontrolsallowindependent

4-bit, 8-bit or combined 16-bit operation. These parts are plug in

replacementsfor54/74ABT16244wherehigherspeed,lowernoise

or lower power dissipation levels are desired.

The FCT16244T/AT/CT/ET are ideally suited for driving

high capacitance loads (>200pF) and low impedance

backplanes. These "high drive" buffers are designed with

power off disable capability to allow "live insertion" of boards

when used in a backplane interface.

TheFCT162244T/AT/CT/EThavebalancedoutputcurrent

levels and current limiting resistors. These offer low ground

bounce, minimal undershoot, and controlled output fall times,

reducing the need for external series terminating resistors

while still providing very high speed operation for loads of less

than 200pF.

• Features for FCT162244T/AT/CT/ET:

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

±16mA (military)

The FCT166244T/AT/CT are suited for very low noise,

point-to-pointdrivingwherethereisasinglereceiver, oravery

light lumped load (<100pF). The buffers are designed to limit

the output current to levels which will avoid noise and ringing

on the signal lines without using external series terminating

resistors.

– Reduced system switching noise

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

VCC = 5V,TA = 25°C

• Features for FCT166244T/AT/CT:

– Light Drive Balanced Output: ±8mA (commercial),

±6mA (military)

The FCT162H244T/AT/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.

– Minimal system switching noise

– Typical VOLP (Output Ground Bounce) < 0.25V at

VCC = 5V,TA = 25°C

• Features for FCT162H244T/AT/CT/ET:

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

– Eliminates the need for external pull up resistors
