3.3V CMOS 16-BIT BUS  
TRANSCEIVER WITH  
IDT74ALVCH162245  
3-STATE OUTPUTS  
AND BUS-HOLD  
DESCRIPTION:  
FEATURES:  
0.5 MICRON CMOS Technology  
TypicaltSK(0) (Output Skew) < 250ps  
This 16-bit bus transceiver is built using advanced dual metal CMOS  
technology. The ALVCH162245 is designed for asynchronous commu-  
nication between data buses. The control-function implementation  
minimizes external timing requirements.  
ESD > 2000V per MIL-STD-883, Method 3015;  
> 200V using machine model (C = 200pF, R = 0)  
0.635mm pitch SSOP, 0.50mm pitch TSSOP,  
and 0.40mm pitch TVSOP packages  
Extended commercial range of – 40°C to + 85°C  
VCC = 3.3V ± 0.3V, Normal Range  
VCC = 2.7V to 3.6V, Extended Range  
VCC = 2.5V ± 0.2V  
CMOS power levels (0.4µW typ. static)  
Rail-to-Rail output swing for increased noise margin  
This device can be used as two 8-bit transceivers or one 16-bit  
transceiver. It allows data transmission from the A bus to the B bus or  
from the B bus to the A bus, depending on the logic level at the direction-  
control (DIR) input. The output-enable (OE) input can be used to disable  
the device so that the buses are effectively isolated.  
The ALVCH162245 has series resistors in the device out-put struc-  
ture ofthe Aportwhichwillsignificantlyreduce line noise whenusedwith  
light loads. This driver has been designed to drive ±12mA at the  
designated threshold levels. The B” port has a ±24mA driver.  
Drive Features for ALVCH162245:  
Balanced Output Drivers: ±12mA (A port)  
High Output Drivers: ±24mA (B port)  
The ALVCH162245 has bus-hold” which retains the inputs’ last state  
whenever the input bus goes to a high impedance. This prevents floating  
inputs and eliminates the need for pull-up/down resistors.  
APPLICATIONS:  
3.3V High Speed Systems  
3.3V and lower voltage computing systems
