74LVCH322244A  
32-bit buffer/line driver; 30 series termination resistors; 5 V  
tolerant input/output; 3-state  
Rev. 3 — 16 December 2011  
Product data sheet  
1. General description  
The 74LVCH322244A is a 32-bit non-inverting buffer/line driver with 3-state outputs. The  
3-state outputs are controlled by the output enable inputs nOE. A HIGH on input nOE  
causes the outputs to assume a high-impedance OFF-state.  
The device is designed with 30 series termination resistors in both HIGH and LOW  
output stages to reduce line noise.  
To ensure the high-impedance state during power-up or power-down, input nOE should  
be tied to VCC through a pull-up resistor; the minimum value of the resistor is determined  
by the current-sinking capability of the driver.  
Inputs can be driven from either 3.3 V or 5 V devices. In 3-state operation, outputs can  
handle 5 V. These features allow the use of these devices in a mixed 3.3 V and 5 V  
environment.  
Bus hold on data inputs eliminates the need for external pull-up resistors to hold unused  
or floating data inputs at a valid logic level.  
2. Features and benefits  
5 V tolerant inputs/outputs for interfacing with 5 V logic  
Wide supply voltage range from 1.2 V to 3.6 V  
CMOS low power consumption  
MULTIBYTE flow-through standard pin-out architecture  
Low inductance multiple power and ground pins for minimum noise and ground  
bounce  
Direct interface with TTL levels  
Integrated 30 termination resistors  
All data inputs have bus hold  
Complies with JEDEC standard:  
JESD8-7A (1.65 V to 1.95 V)  
JESD8-5A (2.3 V to 2.7 V)  
JESD8-C/JESD36 (2.7 V to 3.6 V)  
ESD protection:  
HBM JESD22-A114F exceeds 2000 V  
MM JESD22-A115-B exceeds 200 V  
CDM JESD22-C101E exceeds 1000 V  
Specified from 40 C to +85 C and 40 C to +125 C
