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.
