CY74FCT16373T  
CY74FCT162373T  
SCCS054 - August 1994 - Revised March 2000  
16-Bit Latches  
Features  
Functional Description  
• FCT-E speed at 3.4 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  
• Industrial temperature range of 40˚C to +85˚C  
• VCC = 5V ± 10%  
CY74FCT16373T and CY74FCT162373T are 16-bit D-type  
latches designed for use in bus applications requiring high  
speed and low power. These devices can be used as two  
independent 8-bit latches or as a single 16-bit latch by  
connecting the Output Enable (OE) and Latch (LE) inputs.  
Flow-through pinout and small shrink packaging aid in  
simplifying board layout. The output buffers are designed with  
power-off disable feature that allows live insertion of boards.  
The CY74FCT16373T is ideally suited for driving  
high-capacitance loads and low-impedance backplanes.  
The CY74FCT162373T 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  
CY74FCT162373T is ideal for driving transmission lines.  
CY74FCT16373T Features:  
• 64 mA sink current, 32 mA source current  
• Typical VOLP (ground bounce) <1.0V at VCC = 5V,  
TA = 25˚C  
CY74FCT162373T Features:  
• Balanced 24 mA output drivers  
• Reduced system switching noise  
• Typical VOLP (ground bounce) <0.6V at VCC = 5V,  
TA= 25˚C
