IDT54/74FCT162260AT/CT/ET  
FAST CMOS  
12-BIT TRI-PORT  
BUS EXCHANGER  
Integrated Device Technology, Inc.  
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.)

• Features for FCT16260AT/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  
DESCRIPTION:  
The FCT16260AT/CT/ET and the FCT162260AT/CT/ET  
Tri-Port Bus Exchangers are high-speed 12-bit latched bus  
multiplexers/transceivers for use in high-speed microproces-  
sor applications. These Bus Exchangers support memory  
interleaving with latched outputs on the B ports and address  
multiplexing with latched inputs on the B ports.  
The Tri-Port Bus Exchanger has three 12-bit ports. Data  
may be transferred between the A port and either/both of the  
B ports. The latch enable (LE1B, LE2B, LEA1B and LEA2B)  
inputs control data storage. When a latch-enable input is  
HIGH, the latch is transparent. When a latch-enable input is  
LOW, the data at the input is latched and remains latched until  
the latch enable input is returned HIGH. Independent output  
enables (OE1B and OE2B) allow reading from one port while  
writing to the other port.  
The FCT16260AT/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 for FCT162260AT/CT/ET:  
– Balanced Output Drivers: ±24mA (commercial),  
±16mA (military)  
The FCT162260AT/CT/ET have balanced output drive  
with current limiting resistors. This offers low ground bounce,  
minimal undershoot, and controlled output fall times - reduc-  
ing the need for external series terminating resistors.  
– Reduced system switching noise  
– Typical VOLP (Output Ground Bounce) < 0.6V at  
VCC = 5V,TA = 25°C
