Description
STROBE
1
CD4514BMS and CD4515BMS consist of a 4-bit strobed
latch and a 4-to-16-line decoder. The latches hold the last
input data presented prior to the strobe transition from 1 to 0.
Inhibit control allows all outputs to be placed at
0(CD4514BMS) or 1(CD4515BMS) regardless of the state of
the data or strobe inputs.
INHIBIT 23
The decode truth table indicates all combinations of data
inputs and appropriate selected outputs.
These devices are similar to industry types MC14514 and
MC14515.
The CD4514BMS and CD4515BMS are supplied in these 24
lead outline packages:
Braze Seal DIP
Frit Seal DIP
H4V
H1Z
H4P
Ceramic Flatpack
CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
