1. General description
The 74HC154; 74HCT154 is a 4-to-16 line decoder/demultiplexer. It decodes four binary
weighted address input s (A0 to A3) to sixteen mutually e xclusive outputs (Y0 to Y15). The
device features two inpu t en a ble (E0 an d E1) inputs. A HIGH on either of the input
enables forces the outputs HIGH. The device can be used as a 1-to-16 demultiplexer by
using one of the enable input s as the mu ltiplexed dat a input. When the o ther enable inp ut
is LOW the addressed output will follow the st ate of the applied data . Inputs include clamp
diodes. This enables the use of current limiting resistors to interface inputs to voltages in
excess of VCC.
2. Features and benefits

(1) This is not a supply pin. The substrate is attached to this
pad using conductive die attach material. There is no
electrical or mechanical requirement to solder this pad.
However, if it is soldered, the solder land should remain
floating or be connected to VCC.
