DESCRIPTION
The HCC40101B (extended temperature range)
and HCF40101B (intermediate temperature range)
are monolithic integrated circuits, available in 14-
lead dual in-line plastic or ceramic package and
plastic micro package.
The HCC/HCF40101B is a 9-bit (8 data bits plus 1
parity bit) parity generator/checker. It may be used
to detect errors in data transmission or data retrie-
val. Odd and even outputs facilitate odd or even
parity generation and checking. When used as a
parity generator, a parity bit is supplied along with
the data to generate an even or odd parity output.
When used a parity checker, the received data bits
and parity bits are compared for correct parity. The
even or odd outputs are used to indicate an error in
the received data. Word-length capability is expan-
dable by cascading. The HCC/HCF40101B is also
provided with an inhibit control. If the inhibit control
is set at logical ”1”, the even and odd outputs go to
a logical ”0”.

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 external periods may affect device reliabili ty.
