SCLS175E – MONTH 2003 – REVISED AUGUST 2016 SNx4HCT244 Octal Buffers and Line Drivers With 3-State Outputs
1 Features 3 Description These octal buffers and line drivers are designed
specifically to improve both the performance and
density of 3-state memory address drivers,
clockdrivers, and bus-oriented receivers and
transmitters. The SNx4HCT244 devices are
organized as two 4-bit buffers or drivers with separate
output-enable (OE) inputs. When OE is low, the
device passes noninverted data from the A inputs to
the Y outputs. When OE is high, the outputs are in
the high-impedance state. 1 Operating Voltage Range of 4.5 V to 5.5 V
High-Current Outputs Drive up to 15 LSTTL Loads
Low Power Consumption: 80-ВµA Maximum ICC
Typical tpd = 13 ns
В±6-mA Output Drive at 5 V
Low Input Current of 1 ВµA Maximum
Inputs Are TTL-Voltage Compatible …
