description
The ’AHCT125 devices are quadruple bus buffer
gates featuring independent line drivers with
3-state outputs. Each output is disabled when the
associated output-enable (OE) input is high.
When OE is low, the respective gate passes the
data from the A input to its Y output.
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
SN54AHCT125
is
characterized
for
operation over the full military temperature range
of –55
°C to 125°C. The SN74AHCT125 is
characterized for operation from –40
°C to 85°C.
