LATCHES

DESCRIPTION:

FEATURES:

The FCT16841AT/BT/CT/ET and FCT162841AT/BT/CT/

ET 20-bit transparent D-type latches are built using advanced

dual metal CMOS technology. These high-speed, low-power

latches are ideal for temporary storage of data. They can be

used for implementing memory address latches, I/O ports,

andbusdrivers.TheOutputEnableandLatchEnablecontrols

are organized to operate each device as two 10-bit latches or

one 20-bit latch. Flow-through organization of signal pins

simplifies layout. All inputs are designed with hysteresis for

improved noise margin.

The FCT16841AT/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 FCT162841AT/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

FCT162841AT/BT/CT/ET are plug-in replacements for the

FCT16841AT/BT/CT/ET and ABT16841 for on-board inter-

face applications.

• 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

– VCC = 5V ±10%

• Features for FCT16841AT/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 FCT162841AT/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
