| MOTOROLA SEMICONDUCTOR TECHNICAL DATA Quad 2-Input Data Selector/Multiplexer High-Performance Silicon-Gate CMOS The MC74HC158A is identical in pinout to the LS158. The device inputs are compatible with Standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. These devices route 2 nibbles (A or B) to a single port (Y) as determined by the Select input. The data is presented at the outputs in inverted form for the HC158A. A high level on the Output Enable input sets all four Y outputs to a high level for the HC158A.

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance 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. v v _C _C Lead Temperature, 1 mm from Case for 10 Seconds (Plastic DIP, SOIC or TSSOP Package) * Maximum Ratings are those values beyond which damage to the device may occur.

The data is presented to the outputs in inverted form for the HC158A. OUTPUTS Y0-Y3 (Pins 4,7,9,12) Data outputs. The selected input nibble is presented at these outputs when the Output Enable input is at a low level. The data present on these pins is in its inverted form for the HC158A. For the Output Enable input at a high level, the outputs are at a high level for the HC158A. CONTROL INPUTS Select (Pin 1) Nibble select. This input determines the data word to be transferred to the outputs. A low level on this input selects the A inputs and a high level selects the B inputs. Output Enable (Pin 15) Output Enable input. A low level on this input allows the selected data to be presented at the outputs. A high level on this input sets all of the outputs to a high level for the HC158A.
