DESCRI PTION
TheHCC4099B (extended temperature range) and
HCF4099B (intermediate temperature range) are
monolithicintegratedcircuits,available in16-leaddual
in-line plastic or ceramic package and plastic micro
package. The HCC/HCF4099B 8-bit addressable
latchisaserial-input, parallel-output storageregister
that can perform a variety of functions. Dataare inputtedto a particular bit in the latch whenthat bitis
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 outputscan be continuously readindependent of WRITEDISABLE andaddress inputs.
A masterRESET input is available, whichresets all
bits to a logic ”0” level when RESET and WRITE
DISABLE are at a high level.When RESETis at a
highlevel, andWRITEDISABLE is ata lowlevel,the
latch acts as a 1-of-8 demultiplexer ; the bit that is
addressed has an active output which follows the
data input, whileall unaddressed bits are held to a
logic ”0” level.
