address. Therefore, this should only be done while in the

memory mode (E = HIGH, CL = LOW).

General Description

The CD4099BC is an 8-bit addressable latch with three

address inputs (A0–A2), an active low enable input (E),

active high clear input (CL), a data input (D), and eight out-

puts (Q0–Q7).

Features

■ Wide supply voltage range: 3.0V to 15V

■ High noise immunity: 0.45 V_DD(typ.)

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.

■ Low power TTL: fan out of 2 driving 74L

compatibility: or 1 driving 74LS

■ Serial to parallel capability

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 active output which follows the data input while all

unaddressed bits are held LOW. When operating in the

addressable latch mode (E = CL = LOW), changing more

than one bit of the address could impose a transient wrong

■ Storage register capability

■ Random (addressable) data entry

■ Active high demultiplexing capability

■ Common active high clear
