operates with CMOS input levels For AHCT only:
operates with TTL input levels Specified from
−40to +85 and +125 °C.
DESCRIPTIONThe 74AHC/AHCT244 is a
high-speed Si-gate CMOS device.
The 74AHC/AHCT244 is an octal
non-inverting buffer/line driver with
3-state outputs.
The 3-state outputs are controlledby
the outputs enable inputs 1OE and
2OE.
AHIGHon nOE causes the outputsto
assumea high-impedance OFF state.
FUNCTION TABLESee note1.
Note H= HIGH voltage level;= LOW voltage level;= don’t care;= high-impedance OFF state.
QUICK REFERENCE DATAGND=0 V; Tamb =25 °C; tr =tf≤ 3.0 ns.
Notes CPD is used to determine the dynamic power dissipation (PDin μW). =CPD× VCC2×fi+∑ (CL× VCC2×fo) where:= input frequency in MHz;= output frequency in MHz; (CL× VCC2×fo)= sum of outputs;= output load capacitance in pF;
VCC= supply voltage in Volts. The condition is VI= GNDto VCC.

RECOMMENDED OPERATING CONDITIONS
LIMITING VALUESIn accordance with the Absolute Maximum Rating System (IEC 134); voltages are referenced to GND (ground=0V).
Notes The input and output voltage ratings may be exceeded if the input and output current ratings are observed. For SO packages: above 70 °C the value of PD derates linearly with 8 mW/K.
For TSSOP packages: above 60 °C the value of PD derates linearly with 5.5 mW/K.
