FAST CMOS 20-BIT

BUFFERS

Integrated Device Technology, Inc.

FEATURES:

• Common features:

– 0.5 MICRON CMOS Technology

– High-speed, low-power CMOS replacement for

ABT functions

DESCRIPTION:

The FCT16827AT/BT/CT/ET and FCT162827AT/BT/CT/

ET 20-bit buffers are built using advanced dual metal CMOS

technology. These 20-bit bus drivers provide high-perfor-

mance bus interface buffering for wide data/address paths or

busses carrying parity. Two pair of NAND-ed output enable

controls offer maximum control flexibility and are organized to

operate the device as two 10-bit buffers or one 20-bit buffer.

Flow-through organization of signal pins simplifies layout. All

inputs are designed with hysteresis for improved noise mar-

gin.

The FCT16827AT/BT/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.

The FCT162827AT/BT/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

FCT162827AT/BT/CT/ET are plug-in replacements for the

FCT16827AT/BT/CT/ET and ABT16827 for on-board inter-

face applications.

– 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

– VCC = 5V ±10%

• Features for FCT16827AT/BT/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

• Features for FCT162827AT/BT/CT/ET:

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

±16mA (military)

– Reduced system switching noise

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

VCC = 5V,TA = 25°C
