SCCS065C - August 1994 - Revised September 2001  
16-Bit Registered Transceivers  
Functional Description  
Features  
• 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 16-bit registered transceivers are high-speed,  
low-power devices. 16-bit operation is achieved by connecting  
the control lines of the two 8-bit registered transceivers  
together. For data flow from bus A-to-B, CEAB must be LOW  
to allow data to be stored when CLKAB transitions from  
LOW-to-HIGH. The stored data will be present on the output  
when OEAB is LOW. Control of data from B-to-A is similar and  
is controlled by using the CEBA, CLKBA, and OEBA inputs.  
• Industrial temperature range of –40˚C to +85˚C  
• VCC = 5V ± 10%  
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.  
CY74FCT16952T Features:  
• 64 mA sink current, 32 mA source current  
• Typical VOLP (ground bounce) <1.0V at  
VCC = 5V, TA = 25˚C  
The CY74FCT16952T is ideally suited for driving  
high-capacitance loads and low-impedance backplanes.  
The CY74FCT162952T 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  
CY74FCT162952T is ideal for driving transmission lines.  
CY74FCT162952T Features:  
• Balanced 24 mA output drivers  
• Reduced system switching noise  
• Typical VOLP (ground bounce) <0.6V at  
VCC = 5V, TA= 25˚C  
The CY74FCT162H952T 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.  
CY74FCT162H952T Features:  
• Bus hold retains last active state  
• Eliminates the need for external pull-up or pull-down  
resistors
