SCCS057B - August 1994 - Revised September 2001  
18-Bit Registered Transceivers  
Features  
Functional Description  
• Ioff supports partial-power-down 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  
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). 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  
LOW-to-HIGH 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.  
• Industrial temperature range of −40˚C to +85˚C  
• VCC = 5V ± 10%  
CY74FCT16501T 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.  
CY74FCT162501T Features:  
The CY74FCT16501T is ideally suited for driving  
high-capacitance loads and low-impedance backplanes.  
• Balanced 24 mA output drivers  
• Reduced system switching noise  
THE CY74FCT162501T 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  
• Typical VOLP (ground bounce) <0.6V at VCC = 5V,  
TA= 25˚C  
CY74FCT162H501T Features:  
undershoot  
and

ground  
bounce.  
The  
CY74FCT162501T is ideal for driving transmission lines.  
• Bus hold retains last active state  
• Eliminates the need for external pull-up or pull-down  
resistors  
The CY74FCT162H501T is a 24-mA balanced output part, that  
has “bus hold” on the data inputs. The device retains the input’s  
last state whenever the input goes to high impedance. This  
eliminates the need for pull-up/down resistors and prevents  
floating inputs.
