For high frequency or heavy load considerations, see Chapter 2 of the Motorola HighSpeed CMOS Data Book (DL129/D).

This device contains protection circuitry to guard against damage due to high static voltages or electric fields.However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this highimpedance circuit. For proper operation, Vin and Vout should be constrained to the range GND (Vin or Vout) VCC.

Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused outputs must be left open.



Description

The MC54/74HC354 is identical in pinout to the LS354. The device inputs are compatible with Standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.

The HC354 selects one of eight latched binary Data Inputs, as determined by the Address Inputs. The information of MC74HC354 at the Data Inputs is stored in the transparent 8bit Data Latch when the DataLatch Enable pin is held high. The Address information may be stored in the transparent Address Latch, which is enabled by the activehigh AddressEnable pin.

MC74HC354 outputs are placed in highimpedance states when Output Enable 1 is high, Output Enable 2 is high, or Output Enable 3 is low.

The HC354 has a clocked Data Latch that is not transparent.
