DESCRIPTION
The
HCC4099B
(extended temperature range) and
HCF4099B
(intermediate temperature range) are
monolithic integrated circuits, available in 16-lead dual
in-line plastic or ceramic package and plastic micro
package. The HCC/HCF4099B 8-bit addressable
latch is a serial-input, parallel-output storage register
that can perform a variety of functions. Data are in-
putted 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 in-
dependent of WRITE DISABLE and address inputs.
A master RESET input is available, which resets all
bits to a logic 鈥?鈥?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 鈥?鈥?level.
