IDT54/74FCT16646T/AT/CT/ET  
IDT54/74FCT162646T/AT/CT/ET  
FAST CMOS 16-BIT BUS  
TRANSCEIVER/  
REGISTERS (3-STATE)  
Integrated Device Technology, Inc.  
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 inde-  
pendent 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. Each 8-bit transceiver/register fea-  
tures direction control (xDIR), over-riding Output Enable con-  
trol (xOE) and Select lines (xSAB and xSBA) to select either  
real-time data or stored data. Separate clock inputs are  
provided for A and B port registers. Data on the A or B data  
bus, or both, can be stored in the internal registers by the  
LOW-to-HIGH transitions at the appropriate clock pins. Flow-  
through organization of signal pins simplifies layout. All inputs  
are designed with hysteresis for improved noise margin.  
The IDT54/74FCT16646T/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 "live insertion" of boards when used  
as backplane drivers.  
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  
– VCC = 5V ±10%  
• 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) < 0.6V at  
VCC = 5V,TA = 25°C  
The IDT54/74FCT162646T/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 IDT54/74FCT162646T/AT/CT/ET are plug-in  
replacements for the IDT54/74FCT16646T/AT/CT/ET and  
54/74ABT16646 for on-board bus interface applications.
