CY74FCT16500T  
CY74FCT162500T  
SCCS056A - August 1994 - Revised October 2001  
18-Bit Registered Transceivers  
Features  
Functional Description  
• FCT-C speed at 4.6 ns  
• Ioff supports partial-power- mode operation  
• 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  
• Industrial temperature range of −40˚C to +85˚C  
• VCC = 5V ± 10%  
These 18-bit universal bus transceivers can be operated in  
transparent, latched, or clock modes by combining D-type  
latches and D-type flip-flops. Data flow in each direction is  
controlled by output-enable (OEAB and OEBA), latch enable  
(LEAB and LEBA), and clock inputs (CLKAB and CLKBA)  
inputs. For A-to-B data flow, the device operates in transparent  
mode when LEAB is HIGH. When LEAB is LOW, the A data is  
latched if CLKAB is held at a HIGH or LOW logic level. If LEAB  
is LOW, the A bus data is stored in the latch/flip-flop on the  
HIGH-to-LOW transition of CLKAB. OEAB performs the output  
enable function on the B port. Data flow from B-to-A is similar  
to that of A-to-B and is controlled by OEBA, LEBA, and  
CLKBA.  
CY74FCT16500T Features:  
• 64 mA sink current, 32 mA source current  
• Typical VOLP (ground bounce) <1.0V at VCC = 5V,  
TA = 25˚C  
This device is fully specified for partial-power-down  
applications using Ioff. The Ioff circuitry disables the outputs,  
preventing damaging current backflow through the device  
when it is powered down.  
CY74FCT162500T Features:  
The CY74FCT16500T is ideally suited for driving  
high-capacitance loads and low-impedance backplanes.  
• Balanced 24 mA output drivers  
• Reduced system switching noise  
• Typical VOLP (ground bounce) <0.6V at VCC = 5V,  
TA= 25˚C  
The CY74FCT162500T 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  
CY74FCT162500T is ideal for driving transmission lines.
