OCTAL BUFFERS/DRIVERS
WITH 3-STATE OUTPUTS
SCLS228L – OCTOBER 1995 – REVISED JULY 2003

POST OFFICE BOX 655303
DALLAS, TEXAS 75265
Inputs Are TTL-Voltage Compatible
Latch-Up Performance Exceeds 250 mA Per
JESD 17
description/ordering information
These
specifically to improve both the performance and
density of 3-state memory-address drivers, clock
drivers,
and
bus-oriented
transmitters.
octal
buffers/drivers
are
designed
receivers
and
The ’AHCT244 devices are organized as two 4-bit
buffers/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.
To ensure the high-impedance state during power
up or power down, OE should be tied to V
CC
through a pullup resistor; the minimum value of
the resistor is determined by the current-sinking
capability of the driver.
