CY74FCT16646T  
CY74FCT162646T  
16-Bit Registered Transceiver  
Features  
Functional Description  
• Low power, pin-compatible replacement for ABT  
functions  
• FCT-E speed at 3.8 ns  
• Power-off disable outputs permits live insertion  
• Edge-rate control circuitry for significantly improved  
noise characteristics  
• Typical output skew < 250 ps  
• ESD > 2000V  
• TSSOP (19.6-mil pitch) and SSOP (25-mil pitch)  
packages  
The CY74FCT16646T and CY74FCT162646T 16-bit trans-  
ceivers are three-state, D-type registers, and control circuitry  
arranged for multiplexed transmission of data directly from the  
input bus or from the internal registers. Data on the A or B bus  
will be clocked into the registers as the appropriate clock pin  
goes to a HIGH logic level. Output Enable (OE) and direction  
pins (DIR) are provided to control the transceiver function. In  
the transceiver mode, data present at the high impedance port  
may be stored in either the A or B register, or in both. The  
select controls can multiplex stored and real-time (transparent  
mode) data. The direction control determines which bus will  
receive data when the Output Enable (OE) is Active LOW. In  
the isolation mode (Output Enable (OE) HIGH), A data may be  
stored in the B register and/or B data may be stored in the A  
register. The output buffers are designed with a power-off dis-  
able feature that allows live insertion of boards.

CY74FCT16646T Features:  
• 64 mA sink current, 32 mA source current  
The CY74FCT16646T is ideally suited for driving  
high-capacitance loads and low-impedance backplanes.

The CY74FCT162646T has 24-mA balanced output drivers  
with current limiting resistors in the outputs. This reduces the  
need for external terminating resistors and provides for  
minimal undershoot and reduced ground bounce. The  
CY74FCT162646T is ideal for driving transmission lines.  
CY74FCT162646T Features:  
• Balanced 24 mA output drivers
