DESCRIPTION
The HCC40257B (extended temperature range)
and HCF40257B (intermediate temperature range)
are monolithic integrated circuits, available in 16-
lead dual in-line plastic or ceramic package and
plastic micro package.
The HCC/HCF40257B is a Data Selector/Multi-
plexer featuring three-state outputs which can inter-
face directly with and drive data lines of bus-oriented
systems.

Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress
rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections
of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliabili ty.
* All voltages are with respect to V
