Description
CD4099BMS 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 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 DIS-
ABLE is at a low level, the latch acts as a 1 of 8 demulti-
plexer; 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.
The CD4099BMS is supplied in these 16-lead outline packages:

CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
