74LV244
OCTAL BUFFER/LINE DRIVE; 3-STATE
The
KK
74LV244 is a low-voltage Si-gate CMOS device and is pin and
function compatible with
KK
74HC/HCT244.
The
KK
74LV244 is an octal non-inverting buffer/line driver with 3-state
outputs. The 3-state outputs are controlled by the output enable inputs 1OE
and 2OE. A HIGH on nOE causes the outputs to assume a high impedance
OFF-state.
The
KK
74LV244 is identical to the
KK
74LV240 but has non-inverting
outputs.
Outputs Directly Interface to CMOS, NMOS, and TTL
Operating Voltage Range: 1.2 to 3.6 V
Low Input Current: 1.0
