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.
