DESCRIPTION
HCF4724B is a monolithic integrated circuit
fabricated
in
Metal
technology available in DIP and SOP packages.
HCF4724B, an 8-bit addressable latch, is a
serial-input, parallel output storage register that
can perform a variety of functions. Data is input to
a particular bit in the latch when the bit is
addressed (by means of input A0, A1, A2) and
when WRITE DISABLE is at a low level. When
Oxide
Semiconductor
WRITE DISABLE is high, data entry is inhibited;
however, all 8 outputs can be continuously read
independent of WRITE DISABLE and address
inputs. A master RESET input is available, which
resets all bits to a logic "0" level when RESET and
WRITE DISABLE are at a high level. When
RESET is at a high level, and WRITE DISABLE is
at a low level, the latch acts as a 1-of-8
demultiplexer; the bit that is addressed has an
active output which follows the data input, while all
unaddressed bits are held to a logic "0" level.
