DESCRIPTION  
This 18-bit universal bus transceiver is designed for  
1.65-V to 3.6-V VCC operation.

Data flow in each direction is controlled by  
output-enable (OEAB and OEBA) and clock-enable  
(CLKENAB and CLKENBA) inputs. For the A-to-B  
data flow, the data flows through a single register.  
The B-to-A data can flow through a four-stage  
pipeline register path, or through a single register  
path, depending on the state of the select (SEL)  
input.

Data is stored in the internal registers on the low-to-high transition of the clock (CLK) input, provided that the  
appropriate CLKEN inputs are low. The A-to-B data transfer is synchronized to the CLKAB input, and B-to-A data  
transfer is synchronized with the CLK1BA and CLK2BA inputs.  
The B outputs, which are designed to sink up to 12 mA, include equivalent 26-Ω resistors to reduce overshoot  
and undershoot.  
To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.  
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.  
The SN74ALVCH162525 is characterized for operation from –40°C to 85°C.
