3.3V CMOS 18-BIT  
IDT74ALVCH16901  
UNIVERSAL BUS TRANSCEIVER  
WITH PARITY GENERATORS/  
CHECKERS AND BUS-HOLD  
FEATURES:  
DESCRIPTION:  
• 0.5 MICRON CMOS Technology  
• Typical tSK(o) (Output Skew) < 250ps  
• ESD > 2000V per MIL-STD-883, Method 3015; > 200V using  
machine model (C = 200pF, R = 0)  
This 18-bit universal bus transceiver is built using advanced dual metal  
CMOS technology. The ALVCH16901 is a dual 9-bit to dual 9-bit parity  
transceiver with registers. The device can operate as a feed-through  
transceiver or it can generate/check parity from the two 8-bit data buses in  
eitherdirection.  
• VCC = 3.3V ± 0.3V, Normal Range  
• VCC = 2.7V to 3.6V, Extended Range  
• VCC = 2.5V ± 0.2V  
• CMOS power levels (0.4µ W typ. static)  
• Rail-to-Rail output swing for increased noise margin  
• Available in TSSOP package  
The ALVCH16901 features independent clock (CLKAB or CLKBA),  
latch-enable (LEAB or LEBA), and dual 9-bit clock enable (CLKENAB or  
CLKENBA) inputs. It also provides parity-enable (SEL) and parity-select  
(ODD/EVEN)inputsandseparateerror-signal(ERRAandERRB)outputs  
for checking parity. The direction of data flow is controlled by OEAB and  
OEBA.WhenSELislow,theparityfunctionsareenabled. WhenSELishigh,  
theparityfunctionsaredisabledandthedeviceactsasan18-bitregistered  
transceiver.  
The ALVCH16901 has been designed with a ±24mA output driver. This  
driver is capable of driving a moderate to heavy load while maintaining  
speedperformance.  
The ALVCH16901 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.  
DRIVE FEATURES:  
• High Output Drivers: ±24mA  
• Suitable for heavy loads  
APPLICATIONS:  
• 3.3V high speed systems  
• 3.3V and lower voltage computing systems
