74AHC244Q
Octal Buffer/Line Driver
with 3-State Outputs
GENERAL DESCRIPTION
FEATURES
The 74AHC244Q is an octal buffer/line driver with
3-state outputs. The device can be used as two 4-bit

buffers or one 8-bit buffer. The 1OE and 2OE are two
TA = -40℃ to +125℃
output enable inputs, and each controls four of the
● Wide Supply Voltage Range: 2.0V to 5.5V
● All Inputs with Schmitt-Trigger Action
● Input Level: CMOS Level
�����
3-state outputs. When nOE is set high, the outputs are
�����
in high-impedance state. When nOE is set low, data
transmits from the nAn inputs to the nYn outputs.
● CMOS Low Power Dissipation
● Inputs are Over-Voltage Tolerant
● -40℃ to +125℃ Operating Temperature Range
● Available in a Green TSSOP-20 Package
The over-voltage tolerant inputs can come up to 5.5V.
With this function, this device can be used as a
translator in mixed voltage environment.
This device is AEC-Q100 qualified (Automotive
Electronics Council Standard Q100 Grade 1) and the
use of this device is suitable for automotive applications.

ESD Susceptibility
1. Stresses beyond those listed in Absolute Maximum
Ratings may cause permanent damage to the device.
Exposure to absolute maximum rating conditions for
extended periods may affect reliability. Functional operation
of the device at any conditions beyond those indicated in the
Recommended Operating Conditions section is not implied.
2. The input and output negative voltage ratings may be
exceeded if the input and output clamp current ratings are
observed.
3. The performance capability of a high-performance integrated
circuit in conjunction with its thermal environment can create
junction temperatures which are detrimental to reliability.
HBM.............................................................................4000V
CDM ............................................................................1000V
ESD SENSITIVITY CAUTION
This integrated circuit can be damaged if ESD protections are
not considered carefully. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions.
Failureto observe proper handlingand installation procedures
can cause damage. ESD damage can range from subtle
performance degradation tocomplete device failure. Precision
integrated circuits may be more susceptible to damage
because even small parametric changes could cause the
device not to meet the published specifications.
RECOMMENDED OPERATING CONDITIONS
Supply Voltage, VCC............................................2.0V to 5.5V
Input Voltage, VI.....................................................0V to 5.5V
