This 18-bit (dual-octal) noninverting registered  
transceiver is designed for 2.7-V to 3.6-V V  
operation.  
CC  
The SN74ALVC16901 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 either direction.

2CLKENAB  
The SN74ALVC16901 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) inputs and separate  
error-signal (ERRA or ERRB) outputs for checking parity. The direction of data flow is controlled by OEAB and  
OEBA. When SEL is low, the parity functions are enabled. When SEL is high, the parity functions are disabled  
and the device acts as an 18-bit registered transceiver.  
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.  
The SN74ALVC16901 is available in TI’s thin shrink small-outline (DGG) package, which provides twice the I/O  
pin count and functionality of standard small-outline packages in the same printed-circuit-board area.  
The SN74ALVC16901 is characterized for operation from 40°C to 85°C.
