DESCRIPTION:

The IDT54/74FCT16646T/AT/CT/ET and IDT54/74FCT162646T/AT/CT/ET 16-bit registered transceivers are built using advanced dual metal CMOS technology. These high-speed, low-power devices are organized as two independent 8-bit bus transceivers with 3-state D-type registers. The control circuitry is organized for multiplexed transmission of data between A bus and B bus either directly or from the internal storage registers.

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

• Features for FCT16646T/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 FCT162646T/AT/CT/ET:

– Balanced Output Drivers: ±24mA (commercial), ±16mA (military)

– Reduced system switching noise

– Typical VOLP (Output Ground Bounce)
