16-Bit 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 16-bit transceivers are designed for use in bidirectional  
synchronous communication between two buses, where high  
speed and low power are required. With the exception of the  
CY74FCT16245T, these devices can be operated either as  
two independent octals or a single 16-bit transceiver. Direction  
of data flow is controlled by (DIR), the Output Enable (OE)  
transfers data when LOW and isolates the buses when HIGH.  
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%  
CY74FCT16245T Features:  
The CY74FCT16245T 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 CY74FCT162245T has 24-mA balanced output drivers  
with current limiting resistors in the outputs. This reduces the  
need for external terminating resistors and provides for mini-  
mal undershoot and reduced ground bounce. The  
CY74FCT162245T is ideal for driving transmission lines.  
CY74FCT162245T Features:  
• Balanced output drivers: 24 mA  
• Reduced system switching noise  
• Typical VOLP (ground bounce) <0.6V at VCC = 5V,  
The CY74FCT162H245T 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.  
TA= 25˚C  
CY74FCT162H245T Features:  
• Bus hold on data inputs  
• Eliminates the need for external pull-up or pull-down  
resistors
