MC14529B

Dual 4-Channel Analog

Data Selector

The MC14529B analog data selector is a dual 4–channel or single

8–channel device depending on the input coding. The device is suitable for

digital as well as analog application, including various one–of–four and

one–of–eight data selector functions. Since the device has bidirectional

analog characteristics it can also be used as a dual binary to 1–of–4 or a

binary to 1–of–8 decoder.

• Data Paths Are Bidirectional

• 3–State Outputs

• Linear “On” Resistance

• Supply Voltage Range = 3.0 Vdc to 18 Vdc

• Capable of Driving Two Low–power TTL Loads or One Low–power

Schottky TTL Load over the Rated Temperature Range.

High

Impedance

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 high-impedance circuit. For proper operation, Vin and

Vout should be constrained to the range VSS ≤ (Vin or Vout) ≤ VDD.

Unused inputs must always be tied to an appropriate logic voltage

level (e.g., either VSS or VDD). Unused outputs must be left open.
