description/ordering information
These octal buffers and line drivers are designed
specifically to improve both the performance and
density of 3-state memory address drivers, clock
drivers, and bus-oriented receivers and
transmitters. The ’HCT244 devices are organized
as two 4-bit buffers/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.

FEATURES

· Output capability: bus driver
· ICC category: MSI


GENERAL DESCRIPTION

The 74HC/HCT244 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT244 are octal non-inverting buffer/line drivers 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 “244” is identical to the “240”
but has non-inverting outputs.
