This octal buffer/driver is built using advanced dual metal CMOS
technology. The ALVC244 is organized as two 4-bit line drivers with
separate output-enable (OE) inputs. When
OE
is low, the device passes
data from the A inputs to the Y outputs. When
OE
is high, the outputs are in
the high-impedance state.
The ALVC244 has been designed with a 鹵24mA output driver. This
driver is capable of driving a moderate to heavy load while maintaining
speed performance.
DRIVE FEATURES:
鈥?High Output Drivers: 鹵24mA
鈥?Suitable for Heavy Loads
APPLICATIONS:
鈥?3.3V high speed systems
鈥?3.3V and lower voltage computing systems
