PIN DESCRIPTIONS
DATA INPUTS
D0a – D3a, D0b – D3b (Pins 3, 4, 5, 6, 10, 11, 12, 13)
Data Inputs. With the outputs enabled, the addressed Data
Inputs appear at the Y outputs.
CONTROL INPUTS
A0, A1 (Pins 2, 14)
Address Inputs. These inputs address the pair of Data
Inputs which appear at the corresponding outputs.
Strobe (Pins 1, 15)
Active–low Strobe. A low level applied to these pins en-
ables the corresponding outputs.
OUTPUTS
Ya, Yb (Pins 7, 9)
Noninverting data outputs.
