DALLAS, TEXAS 75265
D Operating Voltage Range of 4.5 V to 5.5 V
D High-Current Outputs Drive Up To 15
LSTTL Loads
D Low Power Consumption, 80-A Max ICC
D Typical tpd = 12 ns
D ±6-mA Output Drive at 5 V
D Low Input Current of 1 A Max
D Inputs Are TTL-Voltage Compatible
D 3-State Outputs Drive Bus Lines or Buffer
Memory Address Registers
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 ’HCT240 devices are organized
as
two
4-bit
buffers/drivers
with
separate
output-enable (OE) inputs. When OE is low, the
device passes inverted data from the A inputs to
the Y outputs. When OE is high, the outputs are
in the high-impedance state.
