CD4099BM CD4099BC 8-Bit Addressable Latch
General Description
The CD4099B is an 8-bit addressable latch with three ad-
dress inputs (A0–A2) an active low enable input (E) active
high clear input (CL) a data input (D) and eight outputs
(Q0 – Q7)
Data is entered into a particular bit in the latch when that bit
is addressed by the address inputs and the enable (E) is
low Data entry is inhibited when enable (E) is high
When clear (CL) and enable (E) are high all outputs are low
When clear (CL) is high and enable (E) is low the channel
demultiplexing occurs The bit that is addressed has an ac-
tive output which follows the data input while all unad-
dressed bits are held low When operating in the address-
able latch mode (E e CL e low) changing more than one
bit of the address could impose a transient wrong address
Therefore this should only be done while in the memory
mode (E e high CL e low)
