74LVC2244A  
Octal buffer/line driver; 30 Ω series termination; 5 V tolerant  
input/output; 3-state  
Rev. 6 — 20 September 2021  
Product data sheet  
1. General description  
The 74LVC2244A is an 8-bit buffer/line driver with 3-state outputs. The device can be used as  
two 4-bit buffers or one 8-bit buffer. The device features two output enables (1OE and 2OE),  
each controlling four of the 3-state outputs. A HIGH on nOE causes the outputs to assume a  
high-impedance OFF-state. Inputs can be driven from either 3.3 V or 5 V devices. This feature  
allows the use of these devices as translators in mixed 3.3 V and 5 V environments.  
Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.  
This device is fully specified for partial power down applications using IOFF. The IOFF circuitry  
disables the output, preventing the potentially damaging backflow current through the device when  
it is powered down.  
2. Features and benefits  
Overvoltage tolerant inputs to 5.5 V  
Wide supply voltage range from 1.2 V to 3.6 V  
CMOS low-power consumption  
Direct interface with TTL levels  
Integrated 30 Ω termination resistors  
IOFF circuitry provides partial Power-down mode operation  
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-A115B exceeds 200 V  
CDM JESD22-C101E exceeds 1000 V  
Specified from -40 °C to +85 °C and -40 °C to +125 °C
