The HCC/HCF4724B 8-bit addressable latch is a
serial-input, parallel-output storage register that can
perform a variety of functions.
Data are inputted to a particular bit in the latch when
that bit is addressed (by means of inputs A0, A1, A2)
and when WRITE DISABLE is at low level. When
WRITE DISABLE is high, data entry is inhibited
however, all 8 outputs can be continuously read in-
dependent 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.
