INPUTS
A0−A3 (Pins 2, 5, 11, 14)
transferred to the outputs when the Select input is at a low
level and the Output Enable input is at a low level. The data
is presented to the outputs in inverted form for the LCX258.
B0−B3 (Pins 3, 6, 10, 13)
transferred to the outputs when the Select input is at a high
level and the Output Enable input is at a low level. The data
is presented to the outputs in inverted form for the LCX258.
Nibble A inputs. The data present on these pins is
Nibble B inputs. The data present on these pins is

OUTPUTS
Y0−Y3 (Pins 4, 7, 9, 12)
these outputs when the Output Enable input is at a low level.
The data present on these pins is in its inverted form for the
LCX258. For the Output Enable input at a high level, the
outputs are at a high level for the LCX258.
Select (Pin 1)
transferred to the outputs. A low level on this input selects
the A inputs and a high level selects the B inputs.
CONTROL INPUTS
Output Enable (Pin 15)
selected data to be presented at the outputs. A high level on
this input sets all of the outputs to 3−state off.
PIN NAMES
Data outputs. The selected input nibble is presented at
Nibble select. This input determines the data word to be
