The 74F756, 74F757 and 74F760 are octal buffers that are ideal for
driving bus lines of buffer memory address registers. The 74F756 is
the open collector version of 74F240, 74F757 is the open collector
version of 74F241 and 74760 is the open collector version of
74F244. These devices feature two Output Enables. OEa and OEb
(or OEb for the 74F757), each controlling four of the outputs.

SF01258
NOTE:
When using open-collector parts, the value of the pull-up resistor greatly affects the value of the tPLH. For example, changing the pull-up resistor
value from 500 to 100 will improve the tPLH up to 50% with only slight increase in the tPHL. However, if the pull-up resistor is changed, the
user must make certain that the total IOL current through the resistor and the total IIL’s of the receivers do not exceed the IOL maximum
specification.

Short-form specification — The data in a short-form specification is extracted from a full data sheet with the same type number and title. For
detailed information see the relevant data sheet or data handbook.
Limiting values definition — Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one
or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or
at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended
periods may affect device reliability.
