DESCRIPTION:

• Common features:

The FCT16543T/AT/CT/ET and FCT162543T/AT/CT/ET

– 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

16-bit latched transceivers are built using advanced dual metal

CMOS technology. These high-speed, low-power devices are

organized as two independent 8-bit D-type latched transceiv-

ers with separate input and output control to permit indepen-

dent control of data flow in either direction. For example, the A-

to-B Enable (xCEAB) must be LOW in order to enter data from

the A port or to output data from the B port. xLEABcontrols the

latch function. When xLEAB is LOW, the latches are transpar-

TSSOP, 15.7 mil pitch TVSOP and 25 mil pitch Cerpack ent. A subsequent LOW-to-HIGH transition of xLEAB signal

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

– VCC = 5V ±10%

putstheAlatchesinthestoragemode. xOEABperformsoutput

enable function on the B port. Data flow from the B port to the

A port is similar but requires using xCEBA, xLEBA, and xOEBA

inputs. Flow-through organization of signal pins simplifies

layout. All inputs are designed with hysteresis for improved

noise margin.

The FCT16543T/AT/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"liveinsertion"ofboardswhenusedasbackplanedrivers.

The FCT162543T/AT/CT/ET have balanced output drive

with current limiting resistors. This offers low ground bounce,

minimal undershoot, and controlled output fall times–reducing

the need for external series terminating resistors. The

FCT162543T/AT/CT/ET are plug-in replacements for the

FCT16543T/AT/CT/ET and 54/74ABT16543 for on-board bus

interface applications.

• Features for FCT16543T/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

• Features for FCT162543T/AT/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
