description
These
quadruple
2-line
to
1-line
data
selectors/multiplexers are designed for 4.5-V to
5.5-V VCC operation.
The ’AHCT258 devices are designed to multiplex
signals from 4-bit data sources to 4-output data
lines in bus-organized systems. The 3-state
outputs do not load the data lines when the
output-enable (OE) input is at the high logic level.
To ensure the high-impedance state during power
up or power down, OE should be tied to VCC
through a pullup resistor; the minimum value of
the resistor is determined by the current-sinking
capability of the driver.
The
SN54AHCT258
is
characterized
for
operation over the full military temperature range
of –55
°C to 125°C. The SN74AHCT258 is
characterized for operation from –40
°C to 85°C.
