CD4724BMS 8-bit addressable latch is a serial-input, paralleloutput 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 a low level. When 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 that data
input, while all unaddressed bits are held to a logic “0” level.
The CD4724BMS is supplied in these 16-lead outline packages:
Braze Seal DIP
Frit Seal DIP
Ceramic Flatpack
H4W
H1F
H6W
CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
