PIN DESCRIPTIONS
ADDRESS INPUTS
A0a, A1a, A0b, A1b (Pins 2, 3, 14, 13)
Address inputs. These inputs, when the respective 1–of–4
decoder is enabled, determine which of its four active–low
outputs is selected.
CONTROL INPUTS
Selecta, Selectb (Pins 1, 15)
Active–low select inputs. For a low level on this input, the
outputs for that particular decoder follow the Address
inputs. A high level on this input forces all outputs to a high
level.
OUTPUTS
Y0a – Y3a, Y0b – Y3b (Pins 4 – 7, 12, 11, 10, 9)
Active–low outputs. These outputs assume a low level
when addressed and the appropriate Select input is active.
These outputs remain high when not addressed or the
appropriate Select input is inactive.
