16-Bit Registers  
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  
CY74FCT16374T and CY74FCT162374T are 16-bit D-type  
registers designed for use as buffered registers in high-speed,  
low power bus applications. These devices can be used as two  
independent 8-bit registers or as a single 16-bit register by  
connecting the output Enable (OE) and Clock (CLK) inputs.  
Flow-through pinout and small shrink packaging aid in  
simplifying board layout.  
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.  
• Industrial temperature range of 40˚C to +85˚C  
• VCC = 5V ± 10%  
CY74FCT16374T Features:  
The CY74FCT16374T is ideally suited for driving  
high-capacitance loads and low-impedance backplanes.  
• 64 mA sink current, 32 mA source current  
• Typical VOLP (ground bounce) <1.0V at VCC = 5V,  
TA = 25˚C  
The CY74FCT162374T 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  
CY74FCT162374T is ideal for driving transmission lines.  
CY74FCT162374T Features:  
• Balanced 24 mA output drivers  
• Reduced system switching noise  
• Typical VOLP (ground bounce) <0.6V at VCC = 5V,  
TA= 25˚C
