Datasheet

1. General description
The 74LV244 is a low-voltage Si-gate CMOS device and is pin and function compatible
with 74HC244 and 74HCT244.
The 74LV244 is an octal non-inverting buffer/line driver with 3-state outputs. The output
enable inputs 1OE
and 2OE control the 3-state outputs. A HIGH on nOE causes the
outputs to assume a high impedance OFF-state. The 74LV244 is identical to the 74LV240
but has non-inverting outputs.
2. Features and benefits
 Wide operating voltage: 1.0 V to 5.5 V
 Optimized for low voltage applications: 1.0 V to 3.6 V
 Accepts TTL input levels between V
