PIN DESCRIPTIONS
INPUTS
A0–A3 (Pins 2, 5, 11, 14)
Nibble A inputs. The data present on these pins is
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)
Nibble B inputs. The data present on these pins is
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.
OUTPUTS
Y0–Y3 (Pins 4, 7, 9, 12)
Data outputs. The selected input nibble is presented at
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)
Nibble select. This input determines the data word to be
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)
Output Enable input. A low level on this input allows the
selected data to be presented at the outputs. A high level on
this input sets all of the outputs to 3–state off.
